Answer:
We conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.
Thus,
option a) is correct.
Explanation:
When there is no air in the space, it is basically a vacuum.
- In other words, the vacuum can be termed as a 'space devoid of matter'.
So, when there is no air in space, it means there is no force that can act on the body.
- Therefore, no matter what objects (heavy or light) we may drop from the same height, they would all hit the ground at the same time.
As there is no force that can act on an object in the vacuum, it means every object in the vacuum seems to stand still while falling.
Therefore, we conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.
Thus,
option a) is correct.
H2O is an example of a compound
according to newton's first law, an object maintains its state of rest or motion unless acted upon by an external force. So a force is required to stop an object at rest and a force is also required to move an object at rest.
when the hockey player send a hockey puck flying across the ice , frictional force from the ice surface acts on the puck in opposite direction of the motion of puck to slow it down and stops it finally.
