B is the answer because a solid would not be able to hold its shape if it was able to move around
Answer:
Newton's first law, an object will stay at rest only if there are no external forces acting on the object or if the net external force acting on the object is zero. Since the barbell is at rest (not moving), the net external force acting on it must be zero
Newton's Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both)
Newton's Third Law of Motion is known as the equal and opposite reaction principle
Answer:
Drop to half of the previous value
Explanation:
Energy stored in capacitor is inversly propotional to the distance between the plates.
Answer:
The speed of the football when it lift your hand is 8.86 m/s.
Explanation:
Given that,
Final speed of the football, v = 0.5 m/s
Height above the ground, s = 4 m
We need to find the speed of the football when it left your hand. The ball will move under the action of gravity. Using third equation of motion as:

So, the speed of the football when it lift your hand is 8.86 m/s. Hence, this is the required solution.
