Answer:
Energy, E = 18 kJ
Explanation:
Given that,
Power of the lightbulb, P = 5 W
We need to find the electrical energy produced by the lightbulb in one hour. We know that electric power is given by the electrical energy produced per unit time.
1 hour = 3600 seconds
Electric power :
or
E = 18 kJ
So, 18 kJ of electrical energy a 5-W lightbulb convert to radiant and thermal energy in one hour.
Waves have the
characteristic that they can of transmit energy. This characteristic depend
only on the medium and its properties. Electro-mechanical waves do not need
medium to transfer its energy, is capable of transmitting it through empty
space (vacuum).
<span>Mechanical
waves require a medium in order to transport their energy. Sound waves are an
example of mechanical way. They can not
travel through vacuum. </span>

Force the glove exerts on the ball
Explanation:
The reaction to this force is the force the glove exerts on the ball.
According to Newton's third ;aw of motion "Action and reaction forces are equal and opposite in direction".
- The action force is the impact of the ball against the players glove.
- The reactive force is the force the glove exerts on the ball.
This reactive force is directed in the opposite direction and it is the reason why the motion of the incoming ball is halted.
