Answer:
5.1 meters
Explanation:
Terra tosses a 0.20kg volleyball up at at a speed of 10 m/s
The height can be calculated as follows
= v^2/2g
= 10^2/2×9.8
= 100/19.6
= 5.1 meters
Hence the height is 5.1 meters
Answer:
Both feel same magnitude force.
Explanation:
Given that
Mass of father = 100 kg
Mass of daughter = 50 kg
From the third law of Newtons :
Every action have it reaction in opposite direction.It means that if any object apply a force on the other object then first object also feel force of same magnitude but in opposite direction.
It means that both father and her daughter will feel same magnitude of same but in opposite direction.
Einstein's equations showed that matter could be converted into energy; and vice-versa

This statement is false. Increasing the two objects' mass (I'm guessing) will actually increase their gravitational force. This is because of the equation:
If the distance was increased, then the statement would be true, but since you are increasing mass, which is proportional to the Force of Gravity, you are in fact, increasing the gravitational force between the two objects.
