if you relate the Doppler effect on sound to the color of light waves, a police car would be the color (A.yellow B.red C.green D

.blue) as it approaches and the color (A.red B.violet C.blue D.green) as it recedes away from the observer.

Answer:

Blue,red

Explanation:

As it gets closer it’s blue and it’s red when it’s traveling away

The Doppler effect says that the observed wavelength is shortened

when the source is approaching the observer, and lengthened when

the source is receding from the observer.

All we can say about the police car and its siren is that the sound/color

has a shorter wavelength as it approaches us, and a longer wavelength

as it recedes.

Any of these pairs of answers would say that:

  A -- A

  C -- A

  D -- A

or

  D -- D

For each of these pairs, the second wavelength is longer than the first one.

(We don't know which pair is the actual one, because we don't know the actual color of the police car.)

A ball is thrown so that its initial vertical and horizontal components of velocity are 30 m/s and 15 m/s, respectively. Estimat
mihalych1998 [28]

Answer:

H = 45 m

Explanation:

First we find the launch velocity of the ball by using the following formula:

v₀ = √(v₀ₓ² + v₀y²)

where,

v₀ = launching velocity = ?

v₀ₓ = Horizontal Component of Launch Velocity = 15 m/s

v₀y = Vertical Component of Launch Velocity = 30 m/s

Therefore,

v₀ = √[(15 m/s)² + (30 m/s)²]

v₀ = 33.54 m/s

Now, we find the launch angle of the ball by using the following formula:

θ = tan⁻¹ (v₀y/v₀ₓ)

θ = tan⁻¹ (30/15)

θ = tan⁻¹ (2)

θ = 63.43°

Now, the maximum height attained by the ball is given by the formula:

H = (v₀² Sin² θ)/2g

H = (33.54 m/s)² (Sin² 63.43°)/2(10 m/s²)

<u>H = 45 m</u>

Inside most ball-point pens is a small spring that compresses as the pen is pressed against the paper. If a force of 0.1 N compr
AnnZ [28]

Answer:

20 N/m

Explanation:

From the question,

The ball-point pen obays hook's law.

From hook's law,

F = ke............................ Equation 1

Where F = Force, k = spring constant, e = compression.

Make k the subject of the equation

k = F/e........................ Equation 2

Given: F = 0.1 N, e = 0.005 m.

Substitute these values into equation 2

k = 0.1/0.005

k = 20 N/m.

Hence the spring constant of the tiny spring is 20 N/m

To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newt
Firdavs [7]

Answer: A.E.

Explanation: To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newton's law of gravitation. The concepts of mass and weight are often confused. In fact, in everyday conversations, the word "weight" often replaces "mass," as in "My weight is seventy-five kilograms"
