1 answer:
Answer:
Kepler's third law
Explanation:
As per Kepler's third law all planets revolve around the Sun in such a way that their square of time period of revolution around the Sun is proportional to the cube of the mean radius.
It is given as
here
c = proportionality constant
R = mean radius
T = time period around the sun
So here all celestial body and all planets revolve as per the Kepler's third law which is also known as law of harmonies

The final velocity of the second ball is +10 m/s
Explanation:
We can solve this problem by using the principle of conservation of momentum. In fact, the total momentum of the system must be conserved before and after the collision, so we can write:
where:
is the mass of the first ball
is the initial velocity of the first ball (we take its direction as positive direction)
is the final velocity of the first ball
is the mass of the second ball
is the initial velocity of the second ball
is the final velocity of the second ball
Re-arranging the equation and substituting the values, we find:
And since the sign is positive, the direction is the same as the initial direction of the first ball.
