First is melts then it expands next it gets cooler Finally it gains ener. Hope this helps you out.
Answer:
Your answer will be 600meters
Answer:
Look to the explanation
Explanation:
<u><em>Work done</em></u> is is the energy transferred to or from an object by means
of a force acting on the object.
Work is positive if energy transferred to the object, and work is
negative if energy transferred from the object.
<em>Work = Force in the direction motion of object × its displacement</em>

The SI unit of the work is joule (J)
<u><em>Power</em></u> is the rate of work
<em>Power = work done ÷ time taken</em>
Power = 
Displacement (s) ÷ time (t) = velocity (v)
<em>Power = Force × velocity</em>

The SI unit of the power is watt (w)
Explanation:
Electrons will gain energy as they are "pushed" from different points in the circuit. This energy is then lost when the electrons flow through circuit components such as a light bulb.
Answer:
The average power developed by a motor is 4905 Watts.
Explanation:
The average power is given by:

Where:
W: is the work
t: is the time = 8.0 s
First, let's find the work:

Where:
F: is the force
d: is the displacement = 10.0 m
The force is in the vertical motion, and since the movement of the mass is at constant speed the force is:

Hence, the average power is:
Therefore, the average power developed by a motor is 4905 Watts.
