Answer:
38.87 m/s
Explanation:
Given that the ball is dropped from a height = 77 m
u = 0 m/s
s = 77 m
a = g = 9.81 m/s²
Applying the expression as:
Applying values as:
<u>The speed with which the ball hit the ground = 38.87 m/s</u>
Answer: C. T
Explanation:
Period is a unit of time; and in the context of waves or oscillations it is defined as <em>"the </em><u><em>time </em></u><em>elapsed between two equivalent points on the wave or oscillation".</em>
<em />
It is important to note Period (denoted by ) is one of the most important factors (along with the amplitude, frequency and velocity) to describe and characterize a wave.
In addition, Period has an inverse relation with the frequency , this means that if we are given the frequency of a wave, we can inmediatly know its Period.
