Answer:
m = 0.01 kg
Explanation:
Given that,
Momentum of the marble, p = 0.15 kg-m/s
Speed of the marble, v = 15 m/s
We need to find its mass. We know that,
Momentum, p = mv
Where
m is the mass
So, the mass of the marble is equal to 0.01 kg.
Explanation:
It is given that,
A car travels 25 m/s forward for 10 s.
Solution,
For a vector, a quantity must have both magnitude as well as the direction. For a scalar, a quantity have only the magnitude. In this case, the car moves in forward direction. This is the only difference between the vector and the scalar.
Out of given option,s the correct option is (c) "The measurement 25 m/s is the only vector quantity because it is a measurement of speed".
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.
Answer:
no
Explanation:
due to the refraction of light,meaning bending of light when it passes from diffrent mediums with diffrent densities
