Answer:
the value of the uk is 400kg
Explanation:
<span>You are given two cars, one in front of the other, that are traveling down the highway at 25 m/s. You are also given a frequency of 500 Hz of the car travelling behind it. You are asked what is the frequency heard by the driver of the lead car. This problem can be solved using the Doppler effect
sound frequency heard by the lead car = [(speed of sound + lead car velocity)/( speed of sound + behind car velocity)] * (sound of frequency of the behind car)
</span>sound frequency heard by the lead car = [(340 m/s + 25 m/s)/(340 m/s - 25 m/s)] * (500 Hz)
sound frequency heard by the lead car = 579 Hz
free fall is a special type of motion in which the only force acting upon an object is gravity. all objects will fall with the same rate of acceleration, regardless of their mass.
You should move this to Biology. Sorry I can't give you an answer though. Its been years since I have taken Biology.
If I had to guess though I would think the answer would be B. Take that with a grain of salt though.
