A. Layer C is the right answer out of all the choices
Answer:
5.7141 m
Explanation:
Here the potential and kinetic energy will balance each other

This is the initial velocity of the system and the final velocity is 0
t = Time taken = 0.04 seconds
F = Force = 18000 N
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
Equation of motion

From Newton's second law

Squarring both sides

The height from which the student fell is 5.7141 m
Answer:
no because there are large ones middieum and small but they're mostly large
Explanation:
If the frequency of a wave increases and it stays in the same medium, then its <em>wavelength decreases</em>.
