Answer:
Explanation:
We are given that
Mass of spherical shell,
=1900 kg
Mass=
Radius of shell=r=5 m
Distance between two masses=r=5.01 m
Because distance measure from center .
Gravitational force
Using the formula
Hence,the gravitational force =
Answer:
<h3>Motion which repeats itself after regular intervals of time is known as periodic motion.</h3>
A wave is a rhythmic movement that carries energy through space or matter.
Impulse = change in momentum = F x dt
Where F is sufficiently large and dt is very small(tending to zero).
Therefore impulse = mass x final velocity - mass x initial velocity
= 975 x 3 - 975 x 0.5
= 2437.5 Kg-m/s.
Hence option C is correct.
Low frequency, low amplitude, or both.
