Work done  = 379.5J

Height  = 173m

Unknown:

Amount of force exerted on the sled  = ?

Solution:

The amount of force she exerted on the sled is the same as her weight.

Work done is the force applied to move a body through a distance.

      Work done  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

     mg  = weight;

        Work done  = weight x h

           379.5 = weight  x  173

           weight  = \(\frac{379.5}{173}\)   = 2.2N

A projectile is any object that is cast, fired, launched, heaved, hurled, pitched, tossed, or flung. Throwing a ball straight up, kicking a ball and imparting momentum at an angle to the horizontal, or simply letting something fall freely are examples of projectile motion.

The charge induced on the interior surface of the electrically neutral cylindrical conductor is +6q.

To find the charge induced on the interior surface of the electrically neutral cylindrical conductor with a suspended charge of -6q, we can follow these steps:

1. First, consider that the total charge within the cavity must be conserved, meaning the sum of the charges inside the cavity should be constant.

2. In this case, the suspended charge inside the cavity is -6q.

3. Since the cylindrical conductor is electrically neutral, it means that the total charge of the conductor is zero.

4. To maintain electrical neutrality and satisfy the conservation of charge, the charge induced on the interior surface of the conductor must be equal in magnitude but opposite in sign to the suspended charge.

5. Therefore, the charge induced on the interior surface is +6q.

Explanation:

The required angle of principle maxima when wavelength and diffraction grating are given is calculated to be 15.07°.

The wavelength is given as 780 nm = 780 × 10⁻⁹ m

It is given that the diffraction grating contains 3300 lines per centimetre.

Distance between the slits d = 1 cm/3300 lines = 10⁻² m/3300 lines = 3×10⁻⁶ m

The angles of principle maxima are to be found out.

We know that,

d sin θ = m λ

where,

d is the distance between slits

θ is the angle with respect to the path of the incident light

m is the order of interference

sin θ = m λ/d

θ = sin⁻¹(m λ/d) =  sin⁻¹[(1× 780 × 10⁻⁹)/(3×10⁻⁶)] = sin⁻¹ (26× 10⁻²) = sin⁻¹(0.26) = 15.07°

Answer:

A centripetal force

Explanation:

The type of force in the given scenario is tension. The correct option is c.

Tension is defined in physics as the pulling force conveyed axially by a string, cable, loop, or similar material, or by every end of a rod, truss member, or similar three-dimensional object.

Tension can also be defined as the action-reaction pair of forces acting at each end of said elements.

Newton's second law states that the tension in the rope must equal the weight of the backed mass.

Tension, the normal force, and friction are all examples of contact forces.

Since the weight is not moving, the acceleration is zero. Even if the acceleration is not zero, this equals zero.

Thus, the correct option is c.

To find the order of energy while converting bagasse to electricity.

Explanation:

The bagasse has chemical energy stored in it.

The bagasse is burned, so chemical energy gets converted into thermal energy.

The thermal energy gets converted into kinetic energy.

The kinetic results in the motion of electrons.

Thus, producing electrical energy.

Hence, the conversion order is XWZY

The lightning strike is approximately 2 kilometers away if you hear the thunderclap 6.0 seconds after seeing the lightning bolt.

When lightning strikes, it produces both light and sound waves. Light waves travel at a much faster speed than sound waves, so we see the lightning before we hear the thunderclap. The speed of sound in air is approximately 340 m/s. To calculate the distance of the lightning strike, we can use the formula:
distance = speed x time
If we know that it took 6.0 seconds for the thunderclap to reach us, we can multiply this time by the speed of sound to find the distance.
distance = 340 m/s x 6.0 s = 2040 m
However, this distance only accounts for the time it took for the sound to reach us. The lightning bolt itself also has to travel from its location to our eyes, but we can assume that it travels at the speed of light, which is much faster than the speed of sound. Therefore, we can ignore the time it takes for the lightning to reach us and conclude that the lightning strike is approximately 2 kilometers away.

Answer:

A. Piccolo

B. The flute would usually have the highest pitch, but because the piccolo is half the size of a flute, it's higher pitched. The piccolo in C has a range from D5 – C8 which is pretty high pitched. This means that the piccolo's range is an octave above that of the flute.

C. The human ear naturally picks out higher notes, so when piccolos play extremely high, we can hear them more easily than the other instruments in a band or orchestra.

D. I'm sorry but I don't know this one.

An object launched at 65° from the horizontal would have the same range (distance travelled) as an object launched at 25° from the horizontal.

The greatest range you can get when you launch a projectile is to aim it at 45° above the horizon.  If you change that angle by something, then the range is shorter by the same amount if you increse OR decrease the angle by the same something.

65° = 45° plus 20°.  So the range will be the same if you launch at an angle of (45° minus 20°).  That's 25°.

Answer:

It should be 75 seconds

Explanation:

Because if it takes 25 seconds from 0 to 5 just multiply by 3

When a nucleus of 235u undergoes fission, it breaks into two smaller, more tightly bound fragments. The binding energy per nucleon for 235-U is 7.6 MeV and 137-Cs is 8.39 MeV.

In experimental physics, nuclear binding energy is the minimal amount of energy needed to separate an atom's nucleus into its component protons and neutrons, also known as nucleons.

The following equation provides the binding energy of a nucleus:

BE = Δmc² in which;

BE = Energy bound

Mass defect = m.

c = the speed of light = 931.49 MeV/u

For 235U:

A = 235

Δm = 1.9150664

BE = 1.9150664 x 931.49 MeV/u.

= BE = 1783.8648 MeV

The formula  of the nucleon's binding energy is BE/A

= BE/A = 235 x 1738.648 MeV

= BE/A = 7.6 MeV

The binding energy for 137-Cs will be:

Mass defect m = 1.23383 unit

= BE=1.123383 u x 31.49 MeV/u = 1149.3003 MeV

Additionally, the binding energy per nucleon, BE/A =

= A = 137

= BE/A = 137 x 1149.3003 MeV

Explanation:

Given parameters:

Mass of freight train  = 270700kg

Acceleration = 40m/s²

Unknown:

Force acting on the train = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

So;

        Force  = 270700 x 40   = 1.08 x 10⁷N

(a) The distance traveled by the electron is 2.74 x 10⁻⁴ m.

(b) The time of motion of the electron is 8.1 x 10⁻¹¹ s.

(c) The speed of the electron when it is halfway between the starting point and the point where the electron reversed direction is 4.78 x 10⁶ m/s.

(a) The distance traveled by the electron is calculated by applying the following formula.

The acceleration of the electron;

F = ma

F = Eq

ma = Eq

a = Eq/m

where;

a = ( 475000 x 1.6 x 10⁻¹⁹ ) / (9.11 x  10⁻³¹)

a = 8.34 x 10¹⁶ m/s²

The distance traveled by the electron;

v² = u² - 2as

before the electron reverse its direction, the final velocity, v = 0

0 = u² - 2as

s = u² / 2a

s = (6760000²) / (2 x  8.34 x 10¹⁶)

s = 2.74 x 10⁻⁴ m

(b) The time of motion of the electron is calculated as;

v = u - at

0 = u - at

at = u

t = u / a

t = (6760000) /  8.34 x 10¹⁶

t = 8.1 x 10⁻¹¹ s

(c) The speed of the electron when it is halfway between the starting point and the point where the electron reversed direction is;

v² = u² - 2a(¹/₂s)

0 = u² - as

u² = as

u = √as

u = √ (8.34 x 10¹⁶ x 2.74 x 10⁻⁴)

u = 4.78 x 10⁶ m/s
