well in my own words, i'd saw the the doppler effect is similar to light because sound has a speed, and light does too.
so my theory is if you go fast enough everything would just become black, or maybe white? idk its hard to explain
but what my point is, is taht the doppler effect works in the same way, like if a car is moving towards you the sound is being emitted from the car and being pushed by the speed of the car making it have a much higher pitch, when the car is going away however it drops to a lower pitch due the the sound waves being DRAGGED by the car.
there hoped this helped I guess
Answer:
c
Explanation:
electronic balance must always be at zero to prevent errors in measured value
From Newton's third law of motion, the force that is exerted to the boy must be the same force exerted to the girl only that the direction is opposite. The net force in this item is,
F = m x a
Girl:
F = (37 kg)(2.3 m/s²)
F = 85.1 N
In the boy's case,
F = m x a
a = F/m
Boy:
a = 85.1 N/63 kg
a = 1.35 m/s²
Answer: 1.35 m/s²
Answer:
192
Explanation:
Volume: h x B x l
12 x 4 x 4
12 x 16
= 192
