Suppose a sound wave and a light wave have the same frequency.
dedylja [7]

Answer:

The light wave has a longer wavelength and has the greater speed.

Explanation:

light has a far more greater speed than sound. The speed of sound in air is about 343m/s while that of light is around  3 *10^{8}m/s

wavelength (λ) =\frac{V}{f}

since the frequencies of sound and light are same from the question, the wavelength would depend on the magnitude of their velocities. Light with a higher speed would have a longer wavelength.

During an automobile crash test, the average force exerted by a solid wall on a 1,700 kg car that hits the wall is measured to b
Molodets [167]

Answer:

14 m/s

Explanation:

Step One:

Given data:

mass of automobile m= 1700kg

Force F= 170,000 N

time t= 0.14s

v= ??

Required

The velocity of the car

Step two:

From the expression given below, we can find the velocity

Ft= mv

make v subject of the formula

v= Ft/m

v= 170000*0.14/1700

v=23800/1700

v=14 m/s
