Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.
#3
One Time period is the time to cover one complete wavelength distance by the wave
#4
relation between time period and frequency is given as
#5
Time period of simple pendulum is given as
so it depends on length of pendulum and acceleration due to gravity

amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
Answer:
h = v₀² / 2g , h = k/4g x²
Explanation:
In this exercise we can use the law of conservation of energy at two points, the lowest, before the shot and the highest point that the mouse reaches
Starting point. Lower compressed spring
Em₀ = K = ½ m v²
Final point. Highest on the path
= U = mg h
As or no friction the energy is conserved
Em₀ = Em_{f}
½ m v₀²² = m g h
h = v₀² / 2g
We can also use as initial energy the energy stored in the spring that will later be transferred to the mouse
½ k x² = 2 g h
h = k/4g x²
