Answer:
it will have a stronger attraction force
Explanation:
Answer:
<em>12.5watts</em>
Explanation:
Power = Workdone/Time
Since workdone = Force * Distance
Power = Force *distance/Time
Given
Force = 150N
Distance = 10m
Time = 2 minutes = 120seconds
Required
Power
Substitute the given values into the formula;
Power = 150 * 10/120
Power = 1500/120
Power = 12.5Watts
Hence his power is 12.5watts

You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
In my opinion,I think the answer is b.You can control variables more easily by doing different things for different purposes.
