Greenhouse Gases, on relation to Earth's atmosphere.
Answer:
push up agaisnt you with equal force.
Answer: 1000 Hz · 0,5 m = 500 m/s
Explanation: speed = frequency · wavelength
Answer:
0.02 s
Explanation:
Take the (+x) direction to be up.
The average velocity v during a time interval Δt is the displacement Δx divided by Δt.
v=Δx/Δt
=x_f-x_i/t_f-t_i (1)
We assume that your height is 1.6m
Solving [1]
Δt=Δx/v
= 0.02 s
