An odd-shaped object rotates at a speed of 10. 0 rev/s. A small 25 g

mass with moment of inertia I=1. 5x10-6 kg∙m2 is dropped onto the

object at a distance of 4. 5 cm from its center of mass. The odd-shaped

object slows to a speed of 9. 0 rev/s. What is the moment of inertia of

the odd-shaped object?

Answers

Answer 1

The moment of inertia of the odd-shaped object is: approximately 1.67x10⁻³ kg∙m².

To find the moment of inertia of the odd-shaped object, we can use the conservation of angular momentum principle. Angular momentum before the mass is dropped equals angular momentum after the mass is dropped.

Initially, only the odd-shaped object is rotating with an angular speed of 10.0 rev/s. After the 25 g mass with a moment of inertia I=1.5x10⁻⁶ kg∙m² is dropped onto the object at a distance of 4.5 cm (0.045 m) from its center of mass, the system's angular speed slows to 9.0 rev/s.

First, let's convert the angular speed from rev/s to rad/s:


Initial angular speed (ω1) = 10.0 rev/s * 2π rad/rev ≈ 62.83 rad/s
Final angular speed (ω2) = 9.0 rev/s * 2π rad/rev ≈ 56.55 rad/s

Let I_obj be the moment of inertia of the odd-shaped object. The angular momentum before and after the mass is dropped can be written as:

I_obj * ω1 = (I_obj + I + m * r²) * ω2

Solving for I_obj, we get:

I_obj = [(I + m * r²) * ω2] / ω1

Substituting the given values:

I_obj = [(1.5x10^-6 kg∙m² + (0.025 kg * (0.045 m)^2)) * 56.55 rad/s] / 62.83 rad/s

After calculating the above expression, we find that the moment of inertia of the odd-shaped object is approximately 1.67x10⁻³ kg∙m².

What is the velocity of the rivet relative to the satellite just before striking it? (c) Given the rivet is 3.00 mm in size, how long will its collision with the satellite last? (d) If its mass is 0.500 g, what is the average force it exerts on the satellite? (e) How much energy in joules is generated by the collision? (The satellite's velocity does not change appreciably, because its mass is much greater than the rivet's.)

Answers

Velocity of the satellite that is orbiting earth is 83.45m/s, which makes the velocity of the rivet relative before striking also 83.45m/s and the time duration of collision is 4.53× 10⁻⁵ s. The avg force that is exerted by the rivet on the satellite is 9.27N and the energy that is generated by the collision is 1.63J.

a) Velocity of the satellite in an orbit 900 km above Earth's surface can be calculated as follows: Formula: `v = sqrt(GM/r)` Where,v = velocity, M = Mass of Earth, r = radius of the orbit (r = R + h)R = radius of the Earth = 6.37 × 10⁶ mh = height above Earth's surface = 900 km = 9 × 10⁵ mG = 6.67 × 10⁻¹¹ N m²/kg²By substituting the given values, we getv = sqrt((6.67 × 10⁻¹¹ × 5.97 × 10²⁴)/(6.37 × 10⁶ + 9 × 10⁵))= sqrt(6.965 × 10³) = 83.45 m/s.

Therefore, the velocity of the satellite in an orbit 900 km above Earth's surface is 83.45 m/s.

b) Velocity of the rivet relative to the satellite just before striking it can be calculated as follows: Velocity of the rivet, `v_rivet = v_satellite * sin(θ)`Where, v_satellite = 83.45 m/sθ = 90°By substituting the given values, we getv_rivet = 83.45 * sin 90°= 83.45 m/s.

Therefore, the velocity of the rivet relative to the satellite just before striking it is 83.45 m/s.

c) The time duration of collision, `Δt` can be calculated as follows:Δt = (2 * r_rivet)/v_rivet, Where,r_rivet = radius of the rivet = 3/2 × 10⁻³ m. By substituting the given values, we getΔt = (2 * 3/2 × 10⁻³)/83.45= 4.53 × 10⁻⁵ s.

Therefore, the time duration of collision is 4.53 × 10⁻⁵ s.

d) The average force exerted by the rivet on the satellite, `F` can be calculated as follows: F = m_rivet * Δv/ΔtWhere,m_rivet = mass of the rivet = 0.5 g = 0.5 × 10⁻³ kgΔv = change in velocity of the rivet = 83.45 m/sΔt = time duration of collision = 4.53 × 10⁻⁵ sBy substituting the given values, we get F = (0.5 × 10⁻³ * 83.45)/4.53 × 10⁻⁵= 9.27 N.

Therefore, the average force exerted by the rivet on the satellite is 9.27 N.

e) The energy generated by the collision, `E` can be calculated as follows: E = (1/2) * m_rivet * Δv²Where,m_rivet = mass of the rivet = 0.5 g = 0.5 × 10⁻³ kgΔv = change in velocity of the rivet = 83.45 m/s. By substituting the given values, we getE = (1/2) * 0.5 × 10⁻³ * 83.45²= 1.63 J.

Therefore, the energy generated by the collision is 1.63 J.

An engineer is designing a runway. She knows that a plane, starting at rest, needs to reach a speed of 180mph at take-off. If the plane can reach this take-off speed in 65.0s, how far will the plane travel before take-off. Assume the plane increases speed steadily.
How far does the plane need to travel during take-off (in given units)?
ft
Could the plane take off on a 10000ft long runway?

Answers

Answer:

The plane would need to travel at least \(8,\!580\; {\rm ft}\) (\(8.58 \times 10^{3}\; {\rm ft}\).)

The \(10,\!000\; {\rm ft}\) runway should be sufficient.

Explanation:

Convert unit of the the take-off velocity of this plane to \(\rm ft\cdot s^{-1}\):

\(\begin{aligned}v &= 180\; {\rm mph} \\ &= 180\; {\rm mi \cdot hrs^{-1}} \times \frac{1\; {\rm hrs}}{3600\; {\rm s}} \times \frac{5280\; {\rm ft}}{1\; {\rm mi}} \\ &= 264\; {\rm ft \cdot s^{-1}}\end{aligned}\).

Initial velocity of the plane: \(u = 0\; {\rm ft \cdot s^{-1}}\).

Take-off velocity of the plane \(v =264\; {\rm ft\cdot s^{-1}}\).

Let \(x\) denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation \(x = ((u + v) / 2) \, t\).

Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration \(t\) times average velocity \((u + v) / 2\).

The distance that the plane need to cover would be:

\(\begin{aligned}x &= \left(\frac{u + v}{2}\right)\, t \\ &= \frac{0\; {\rm ft \cdot s^{-1}} + 264\; {\rm ft \cdot s^{-1}}}{2} \times 65.0\; {\rm s} \\ &= 8.58\times 10^{3}\; {\rm ft}\end{aligned}\).

What do you think would be the best way to describe sound levels? (Hint: Would a change in scale help?)

Answers

The best way to describe sound levels is through a ratio scale.

The decibel scale, which measures sound levels, is best described as a ratio scale. While the decibel scale is logarithmic, it can be transformed into a linear ratio scale by using a reference point. By selecting a reference point as the softest sound the human ear can hear unaided (0 dB), we establish a meaningful zero point on the scale. Any sound level above this reference point can be expressed as a positive value, indicating its magnitude relative to the softest audible sound. The logarithmic nature of the decibel scale still holds, with each increase of 10 dB representing a tenfold increase in sound intensity. However, by anchoring the scale to a fixed reference point, we can now quantify and compare sound levels in a meaningful way, making it a ratio scale.

A particle moves along the x-axis so that its acceleration at any time t≥0 is given by a(t)=12t−4. At time t=1, the velocity of the particle is v(1)=7 and its position is x(1)=4.

Answers

Given that a particle moves along the x-axis so that its acceleration at any time t0 is given by a(t) = 12t - 4, At time t = 1, the velocity of the particle is v(1) = 7, and its position is x(1) = 4.

To find the velocity and position of the particle, we need to integrate the acceleration, a(t), and then solve the resulting equations for the constants of integration.

To solve for C, we use the fact that v(1) = 7:v(1) = 6(1)^2 - 4(1) + Cv(1)

= 2 + C

Thus, C is 5. Now, we can write the velocity of the particle as:

v(t) = 6t^2 - 4t + 5

To find the position of the particle, we integrate the velocity.

v(t) = dx(t)/dt ⇒ dx(t)

= v(t)dt∫dx(t)

= ∫v(t)dtx(t)

= ∫(6t^2 - 4t + 5)dt

X(t) = 2t^3 - 2t^2 + 5t + K

where K is the constant of integration. To solve for K, we use the fact that

x(1) = 4:X(1)

= 2(1)^3 - 2(1)^2 + 5(1) + KX(1)

= 5 + K

Thus, K = -1.

Now, we can write the position of the particle as:

X(t) = 2t^3 - 2t^2 + 5t - 1

Hence, the velocity of the particle is v(t) = 6t2 - 4t + 5, and the position of the particle is X(t) = 2t3 - 2t2 + 5t - 1.

Answers

Uneven bombardment on different sides by water molecules.

Water is made up of little, swiftly moving particles. The pollen grains move on the surface of water because they are continually being struck by the swiftly moving water particles (the water particles or water molecules themselves are invisible under the microscope due to their extreme small size). Therefore, even though the water molecules (particles) are too small to discern, their impact on the pollen grains can be readily seen. Brownian motion is exemplified by the haphazard movement of visible particles (pollen grains) brought about by much smaller unseen water particles.The pollen grains will move with some justification if Brownian motion is used to explain the observation in the question.Brownian motion is the irregular (constant but random) movement of small particles suspended in a fluid, according to its definition. A disturbance in the medium holding the suspended particles is what is responsible for the motion. In other words, it is brought on by some fluid disruptions, which may have been brought on by some bombardments.

what is the electric flux through a circular area of radius 1.43 that lies in the x-y plane?

Answers

The electric flux through a circular area of radius 1.43 in the x-y plane can be determined using Gauss's law and the concept of electric field lines.

Gauss's law states that the electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of free space (ε₀). In this case, we have a circular area in the x-y plane, and we want to find the electric flux through it.

To calculate the electric flux, we need to consider the electric field passing through the circular area. Since the area lies in the x-y plane, the electric field is likely perpendicular to the surface and uniform in magnitude.

If we assume the circular area contains a positive charge, the electric field lines would radiate outward from the center of the circle. The electric flux would then be proportional to the number of electric field lines passing through the circular area. The magnitude of the electric flux would depend on the total electric field passing through the area.

To determine the exact value of the electric flux, we would need more information about the charge distribution and the electric field. However, we can conclude that the electric flux through the circular area of radius 1.43 in the x-y plane would be related to the magnitude of the electric field passing through it and the total charge enclosed by the circular area.

Therefore, the velocity of the ball just before it hits the ground is approximately 22.1 m/s. Therefore, the closest value to this option is 21.0 m/s.

When a ball of mass 0.25 kg falls from a height of 50 m, we can calculate its velocity using the principle of conservation of energy. According to this principle, the sum of the potential and kinetic energy of an object remains constant.

Therefore, we can equate the potential energy at the initial height to the kinetic energy at the final velocity.Let's calculate the potential energy of the ball at the initial height

:Eg = mghEg = 0.25 kg × 9.81 m/s² × 50 m

Eg = 122.625 J

This is the energy that the ball has due to its position. As it falls, this energy is transformed into kinetic energy. At the moment the ball reaches the ground, all the potential energy has been transformed into kinetic energy

.Ek = 1/2mv²Ek = Egv² = 2Ek/mv = √(2Ek/m)

Let's plug in the values we obtained:Eg = 122.625 Jm = 0.25 kgv = √(2Ek/m)

A solenoid is made of N = 6500 turns, has length L = 25 cm, and radius R = 1.1 cm. The magnetic field at the center of the solenoid is measured to be B = 1.9 x 10^-1 T.I = B L/( μ0 N )Find the numerical value of the current in milliamps.

Answers

The numerical value of the current in the solenoid is approximately 2.88 mA. To find the current in the solenoid, we will use the formula you provided: I = B * L / (μ₀ * N). Here, B is the magnetic field, L is the length of the solenoid, N is the number of turns, and μ₀ is the permeability of free space, which is approximately 4π x 10⁻⁷ T·m/A.

Given the values:
B = 1.9 x 10⁻¹ T
L = 0.25 m (converted from 25 cm)
N = 6500 turns
μ₀ = 4π x 10⁻⁷ T·m/A

Plugging these values into the formula:
I = (1.9 x 10⁻¹ T) * (0.25 m) / ((4π x 10⁻⁷ T·m/A) * 6500)
After solving for I, we get:
I ≈ 0.00288 A
To convert the current to milliamps, multiply by 1000:
I ≈ 2.88 mA

Therefore, the numerical value of the current in the solenoid is approximately 2.88 mA.

You hold a shiny tablespoon at arm's length and look at the front side of the spoon.
(a) Is the image you see of yourself upright or inverted?
upright / inverted
(b) Is the image enlarged or reduced?
enlarged / reduced
(c) Is the image real or virtual?
real / virtual

Answers

(A) The image you see of yourself in the shiny tablespoon is inverted.

(B) The image you see of yourself in the shiny tablespoon is reduced.

(C) The image you see of yourself in the shiny tablespoon is virtual.

A) When you look at the front side of the spoon, the light rays reflecting off your face or any other object get reflected by the curved surface of the spoon. This reflection follows the laws of reflection, resulting in an inverted image. Therefore, the image you see of yourself in the spoon is inverted.

B)  In this case, the shiny tablespoon acts as a concave mirror. Concave mirrors can produce reduced images depending on the position of the object relative to the mirror's focal point. When the object is held at arm's length, the image formed in the spoon is smaller in size compared to the actual object. Hence, the image you see of yourself in the spoon is reduced.

C) A virtual image is formed when the light rays do not physically converge at the location of the image. In the case of a spoon, the reflected rays from the curved surface do not intersect to form a real image that can be projected onto a screen. Instead, your eyes perceive the apparent image formed by the reflected rays, which is known as a virtual image. Therefore, the image you see of yourself in the spoon is virtual.

Option (A) inverted, (B) reduced, and (C) virtual are the correct answers.

how many additional electrons can a fluorine atom attract

Answers

Answer: Fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion wit a 1- charge.

Explanation:

A fluorine atom can attract one additional electron to fill its outermost shell and achieve a stable electron configuration. This ability to attract electrons is due to fluorine's high electronegativity, which is a result of its small atomic size and high nuclear charge. The strong attraction between fluorine and electrons makes it highly reactive and capable of forming strong chemical bonds with other elements.

Atoms are composed of positively charged protons, negatively charged electrons, and neutral neutrons. The number of electrons in an atom determines its chemical properties, as the electrons are involved in chemical bonding. Some atoms have a tendency to attract additional electrons to fill their outermost electron shell, which can result in the formation of ionic or covalent bonds. Fluorine is one such atom that has a strong tendency to attract additional electrons due to its high electronegativity.

Fluorine is a highly electronegative element, meaning it has a strong tendency to attract electrons towards itself. This is due to its small atomic size and high nuclear charge, which results in a strong electrostatic attraction between the positively charged nucleus and the negatively charged electrons.

Fluorine has seven electrons in its outermost shell, which means it is only one electron short of having a full outer shell. This makes fluorine highly reactive, as it has a strong tendency to attract an additional electron to fill its outer shell and achieve a stable electron configuration. When fluorine attracts an additional electron, it forms a negative ion called fluoride.

The strength of fluorine's electronegativity can be quantified using a scale called the Pauling scale. Fluorine has the highest electronegativity of all the elements on the periodic table, with a Pauling electronegativity value of 4.0. This means that fluorine can attract electrons more strongly than any other element, making it highly reactive and capable of forming strong chemical bonds with other elements.
