Answer:
s=800 m
Explanation:
Given that,
Acceleration of a runner, a = 4 m/s²
Time, t = 20 seconds
We need to find the distance covered by her. Initially, she was at rest. It means its initial velocity is equal to 0. So, using second equation of motion as follows :
Herre, u = 0
So, she will cover a distance of 800 m.

Explanation:
Answer:
a. one-fourth its original value.
Explanation:
Sound is threated as a spherical wave. The intensity of the sound is inversely proportional to the area of the wavefront (). Therefore, it is inversely proportional to the square of the distance (r) to the sound source. So, if you double your distance, the intensity of the sound reduces to one-fourth its original value.
