Answer:
∴The air cannot be made to flow in with the given pump at the given conditions.
Explanation:
Given:
- gauge pressure of bicycle tyre,
- length of cylinder of the pump,
- area of the the cylinder of the pump,
- we have the density of air at STP,
The piston must be pushed more than the pressure inside the tyre:
∴The air cannot be made to flow in with the given pump at the given conditions.
Inertia. It also is the tendency of an object in motion to stay in motion in one specific direction.
Answer:Balance Forces
Explanation:
Balanced Forces are equal in magnitude and opposite in direction that acts on the same body. Whenever balanced forces act on an object the object is either still or moving in the same direction with constant velocity.
example of Balanced Forces are
- Consider a block lying on the ground and is being pulled by two forces of equal magnitude but in acting in the opposite direction. As a result, the block is at rest.
because as the distance increases the gravitational force decreases so the weight of a body decreases
