(a) The time elapses before the motorcycle is moving as fast as the car is 2.6296 second.

(b) The motorcycle is 25.93 meter far from the car when it reaches this speed.

Acceleration is rate of change of velocity with time. Si unit of acceleration is meter/second² (m/s²).

Speed of the car = 71 km/h = 71 ×5/18 m/s = 19.722 m/s.

Acceleration of the  police motorcycle = 7.5 m/s²

Hence, Time taken by the motorcycle  to be  as fast as the car = 19.722 ÷ 7.5 s

= 2.6296 second.

The distance between the motorcycle  and the car

= (19.722×2.6296 - 1/2×7.5 × 2.6296²) meter

= 25.93 meter.

Answer:

8.6 meters to south east

Explanation:

Displacement is change in position or a distance between initial position to final position.

Since a person walks to east and then to the south, it forms a right triangle path. We can use Pythagoras Theorem to help finding the displacement:

\(\displaystyle{\vec s = \sqrt{s_x^2 + s_y^2}}\)

Where \(\displaystyle{\vec s}\) is displacement, \(\displaystyle{s_x}\) is horizontal distance (east) and \(\displaystyle{s_y}\) is vertical distance (south). Therefore:

\(\displaystyle{\vec s = \sqrt{5^2 + 7^2}}\\\\\displaystyle{\vec s = \sqrt{25+49}}\\\\\displaystyle{\vec s = \sqrt{74}}\\\\\displaystyle{\vec s = 8.6 \ \, \sf{meters \ \, to \ \, south \ \, east}}\)

Therefore, the displacement is 8.6 meters to south east.

The caps used with boomwhacker tubes alter the sound of the notes by changing the effective length of the air column inside the tube.

This modification affects the fundamental frequency produced when the tube is struck or tapped against a surface.The fundamental frequency determines the pitch of the sound we hear.

When a boomwhacker tube is struck without any cap, the air column inside vibrates at its natural frequency, producing a specific pitch. By adding caps to the tube, we effectively shorten its length, which increases the frequency of the vibrations and raises the pitch. Conversely, removing caps increases the effective length, lowering the frequency and lowering the pitch.

To visualize this, imagine a tube with a cap on one end. The cap acts as a barrier, preventing the air column from vibrating in that direction. Therefore, the effective length of the tube becomes the distance between the cap and the open end. This shorter length results in a higher pitch. Removing the cap increases the effective length, resulting in a lower pitch.By using different combinations of caps on the boomwhacker tubes, we can produce a range of pitches, creating a musical and colorful experience.

Answer: 30 cm.

The situation described is that of two sources of sound waves that are separated by some distance. The two waves interfere with each other constructively at some points and destructively at others. When they interfere constructively, the amplitude (and intensity) of the sound wave is greater than when they interfere destructively.

When the speakers are 40 cm apart, the waves that they produce are in phase at some points on the axis, leading to constructive interference and a maximum in the intensity of the sound. As the distance between the speakers is increased beyond 40 cm, the points of constructive interference move farther apart, and the intensity of the sound decreases. When the speakers are 50 cm apart, the waves that they produce are exactly out of phase at some points on the axis, leading to complete destructive interference and a minimum in the intensity of the sound.

If the separation between the speakers continues to increase, the points of constructive interference will move closer together again, and the intensity of the sound will increase. The separation between the speakers at which the intensity of the sound will again be a maximum can be found using the following equation:

d = λ/2 + nλ

where d is the separation between the speakers, λ is the wavelength of the sound wave, and n is an integer that represents the number of half-wavelengths between the speakers.

At the maximum, the separation is an even multiple of half the wavelength, so we can use the formula above with n = 1. The wavelength can be found from the distance between the speakers at the minimum, which is 50 cm, and the distance at the maximum, which is 40 cm:

λ = 2(d_max - d_min) = 20 cm

Substituting λ and n into the formula gives:

d = λ/2 + nλ = 10 cm + 20 cm = 30 cm

Therefore, the sound intensity will be a maximum again when the separation between the speakers is 30 cm.

In general, option c - warming it up on the stove - is often an effective method to increase the reaction rate.

Increasing the temperature of a reaction generally leads to faster reaction rates. This is because higher temperatures provide more thermal energy to the reactant particles, causing them to move faster and collide more frequently. The increased collision frequency and energy lead to more successful collisions and a higher likelihood of effective molecular interactions, which speeds up the reaction. On the other hand, options a and b - putting it in the fridge where it is cold or covering it with a blanket to make it dark - are unlikely to have a significant effect on the reaction rate. While temperature can influence reaction rates, cooling the reaction or making it dark typically reduces the kinetic energy of the particles, resulting in slower reaction rates. Option d - there is nothing you can do to change the speed of the reaction - is not accurate. The reaction rate can be influenced by various factors such as temperature, concentration, catalysts, and surface area, among others. By manipulating these factors, it is often possible to control and change the speed of a reaction. Hence option c, is correct

At A and C, there is constructive interference occur.

Constructive interference happens when the maxima of two waves combine (the waves are in phase), resulting in a wave whose amplitude is equal to the total of the amplitudes of the separate waves. In a similar way, the wave minima would line up.

The intersection of the lines (indicating peaks) is when constructive interference happens. To put it another way, when two waves are in phase, they interact positively. When two waves are fully out of phase (their peak is in the middle), destructive interference happens.

The time will be the same for both horizontal and vertical component. The initial speed is 10.7 m/s

Speed is a distance travel per time taken. It is a scalar quantity and it is measured in m/s

Given that a person standing at the edge of a seaside cliff kicks a rock horizontally of the cliff from a height of 52 m and it lands a distance of 35 m from the base of the cliff.

The rock will move vertically downward with initial velocity = 0. The time taken will be constant. That is, same horizontally.

Let us first calculate the time by using the formula

h = ut + 1/2gt²

Where

Substitute all the necessary parameters into the formula

52 = 0 + 1/2 × 9.8 × t²

52 = 4.9t²

t² = 52/4.9

t² = 10.6

t = √10.6

t = 3.26 s

The speed at which the rock was initially kicked can be found by

R = Ut

35 = U × 3.26

U = 35/3.26

U = 10.7 m/s

Pressure gauge is located at the bottom of the container thus, the depth of the mercury = 11.05 cm

Pressure refers to the force applied on a unit area of a surface. It works parallel to the pressure-applied surface. Pressure = force multiplied by the area on which it operates. The stronger the power, the smaller the area.

Given that,

pressure exerted by block (\(P_{B}\))= weight / cross-section area of block

\(P_{B}\) = (1 ×9.81) ÷ (10 × 10⁻⁴)

     = 9810 Pa

Now, pressure at bottom of container is given as:

\(P_{Bottom}\) = \(P_{B}\) + ρ × g × h + ρ₁ × g × h₁  

[ ρ = density of water,

ρ₁ = density of Hg,

h = height of water and

h₁ = height of Hg ]

Thus, 27000 = 9810 + (1000 × 9.81 × 0.25) + (13600 × 9.81 × h₁)

h₁ = 14737.5 ÷ 133416

h₁ = 0.1105 m

c.  The change in electric potential energy (in J) as the bead moves from A to B is  -2.025 × 10⁻⁶ J

d. The potential difference (in V) between A and B is -60 V

The magnitude of the electric force on the charge is given by F = qE where

So, substituting the values of the variables into the equation, we have

F = qE

F = 37.0 × 10⁻⁹C × 285 N/C

= 10545 × 10⁻⁹ N

= 10.545 × 10⁻⁶ N

= 1.0545 × 10⁻⁵ N

Since the electric field is pointing to the right and the charge is positive, so, the direction of the electric force is to the right.

So, the magnitude of the electric force on the bead is 1.0545 × 10⁻⁵ N  and its direction is to the right.

The work done on the bead by the electric force is W = Fd where

So, substituting the values of the variables into the equation, we have

W = Fd

= 1.0545 × 10⁻⁵ N  × 0.192

= 2.02464 × 10⁻⁶ J

≅ 2.025 × 10⁻⁶ J

So, the work done on the bead is  2.025 × 10⁻⁶ J

From work-energy principles, the work done by the bead, W equal the change in electric potential energy of the bead ΔU.

ΔU = -W

Since W = 2.025 × 10⁻⁶ J

ΔU = -W

= -2.025 × 10⁻⁶ J

So, the change in electric potential energy (in J) as the bead moves from A to B is  -2.025 × 10⁻⁶ J

The potential difference between A and B is given by ΔV = ΔU/q where

So, substituting the values of the variables into the equation, we have

ΔV = ΔU/q

ΔV =  -2.025 × 10⁻⁶ J/37.0 × 10⁻⁹C

Answer:

37.3 km/h at N 2.70° E

Explanation:

Find the horizontal and vertical components of the initial velocity (u) and final velocity (v).  Remember that N 55° E means 55° east of north.

uₓ = 55.0 km/h

uᵧ = 0 km/h

vₓ = 65.0 km/h × sin 55° = 53.24 km/h

vᵧ = 65.0 km/h × cos 55° = 37.28 km/h

Find the difference.

vₓ − uₓ = -1.76 km/h

vᵧ − uᵧ = 37.28 km/h

The magnitude is:

|v − u| = √((-1.76 km/h)² + (37.28 km/h)²)

|v − u| = 37.3 km/h

The direction is:

θ = tan⁻¹(37.28 / -1.76)

Since focal length cannot be negative for a converging lens, we take the positive value: f ≈ 41 cm Option C

To determine the focal length of the lens, we can use the lens formula, which relates the object distance (u), image distance (v), and focal length (f) of a lens. The lens formula is given by:

1/f = 1/v - 1/u

In this case, the object distance (u) is 25 cm and the image distance (v) is 64 cm. We can substitute these values into the lens formula to solve for the focal length:

1/f = 1/v - 1/u

1/f = 1/64 cm - 1/25 cm

To simplify the equation, we can find a common denominator:

1/f = (25 - 64) / (64 * 25)

1/f = -39 / (64 * 25)

Now, we can invert both sides of the equation to solve for the focal length:

f = (64 * 25) / -39

f ≈ -41.03 cm

Since focal length cannot be negative for a converging lens, we take the positive value:

f ≈ 41 cm

Therefore, the correct answer is option C) 41 cm.

It's important to note that in the lens formula, distances are measured with respect to the lens, with positive values indicating distances on the opposite side of the incident light. The negative value obtained for the focal length indicates that the lens is a converging lens, as expected. Option C

Answer:

a)  F₃ = 109.5 N ,     θ₃ = 38.35,  b)   m = 0.429 kg

Explanation:

For this force addition exercise, let's decompose the forces into a coordinate system

strength 1

          cos 70 = F₁ₓ / F₁

          sin 70 = \(F_{1y}\) / F₁

          F₁ₓ = F₁ cos 70

         F_{1y} = F₁ sin 70

          F₁ₓ = 45 cos 70 = 15.39 N

          F_{1y} = 45 sin70 = 42.29 N

Strength 2

         cos 20 = F₂ₓ / F₂

         sin 20 = F_{2y} / F₂

         F₂ₓ = F₂ cos 20

         F_{2y} = F₂ sin20

         F₂ₓ = 75 cos 20 = 70.48 N

         F_{2y} = 75 sin 20 = 25.65 N

a) in the first part we are asked to find the magnitude of force 3 so that the body is in equilibrium

X axis

         ∑ Fₓ = 0

          F₁ₓ + F₂ₓ + F₃ₓ = 0

          F₃ₓ = - F₁ₓ - F₂ₓ

          F₃ₓ = - 15.39 - 70.48

          F₃ₓ = - 85.87 N

Y Axis

         ∑ F_{y}  = 0

         F_{1y} + F_{2y} +F_{3y}  = 0

         F_{3y} = - F_{1y} -F_{2y}

         F_{3y} = - 42.29 - 25.65

         F_{3y} = - 67.94 N

the magnitude of this force can be found using the Pythagorean theorem

         F₃ = √ (F₃ₓ² + F_{3y}^2)

         F₃ = √ (85.87² + 67.94²)

         F₃ = 109.5 N

The direction of this force can be found using trigonometry

          tan θ =  F₃ = \(F_{3y}\) / F₃ₓ

          θ₃ = Tan⁻¹ (67.94 / (85.87))

          θ₃ = 38.35º

since the two vectors are negative this angle is in the third quadrant, measured from the positive side of the x axis is

          θ₃ = 180 + 38.53

          θ₃ = 218.35º

b) I think you have an error in your statement, we have two possibilities:

1) If we eliminate the third force, what is the mass

it should say: "if we apply the third force force ...", they ask that we find the masses of the vehicle, let's use Newton's second law

X axis

       F₁ₓ + F₂ₓ = m a

       15.39 + 70.48 = m 200

        m = 85.87 / 200

        m = 0.429 kg

2) If the force F3 is in the first quadrant

        F1x + F2x + F3x = m a

        m = (15.39 + 70.48 + 85.87) / 200

        m = 0.8587 kg
