D - Weight is a constant no matter where you are located

This is false as your weight and the weight of any object changes depending on the gravitational pull of a planet - for instance, from the Earth to the moon.

Hope this helps!

posledela
Explanation:

first, find the circumference of the wheel by using the formula 2(pi)(r):

2(pi)(19) = 119.380521

divide by 25 secs

119.380521/25 = 4.77522083

round to the nearest tenth is 4.8, so the speed is 4.8mm/sec

A source emits sound with a frequency of 860 Hz. It is moving at 20.0 m/s toward a stationary reflecting wall. If the speed of s
Galina-37 [17]

Answer:

f_o=860\ Hz

Explanation:

Given:

  • original frequency of sound wave, f=860\ Hz
  • speed of the sound source, v_s=20\ m.s^{-1}
  • original speed of sound wave from the source, s=343\ m.s^{-1}

<u>According to the Doppler's effect:</u>

\frac{f_s}{f_o} =\frac{s+v_s}{s-v_o}

The sound is reflected from the wall and the source is moving towards the wall and observer is also riding the same source.

The velocity of the observer, v_o=-20\ m.s^{-1}

\frac{860}{f_o} =\frac{s+20}{s-(-20)}

f_o=860\ Hz
