A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?

50 W

Explanation:

Given :Force applied = 100 NDistance covered = 5 metresTime = 10 secondsTo find :

Power

Solution :

For calculating power, we first need to know about the work done.

Now, substituting values in the above formula;

Work = 100 × 5

= 500 Nm or 500 J

We know that,

Substituting values in above formula;

Power = 500/ 10

= 50 Nm/s or 50 W

Hence, power = 50 W .

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
