Answer:
I think it's dio to atmospheric pressure.
Electromagnetic radiation waves:
They can be either infared radiation or visible light
We cannot see I fared radiation but it is how some energy is transferred
<span>B. This is because P-waves is shorthand for Pressure-waves. Pressure waves compress and stretch along the direction of motion.</span>
Answer:
Explanation:
given,
speed of length of travel = 0.86 c
length of tunnel = 88 m
Assume length of super train = 205 m
An observer at rest in the tunnel's reference frame will observe the train's length to be contracted:
L' = L₀ / γ
L' is the length the observer measures,
L₀ is the proper length of the train
