Jolie is on the weightlifting team at her school. She must lift as much weight as possible from the ground to a standing straight position. How much work will Jolie do if she uses a force of 5N to lift 150 pounds to a height of 1.5m? 0 2.3) O 6.5) 7.5) 0 3.3)

=7.5J

Explanation:

  Step one:

given data

the applied force F=5N

the distance = 1.5m

Step two:

Required

work done by Jolie

Now by definition, the work done is the applied times the distance which the force is applied

Wd= F*D

Wd= 5*1.5

Wd=7.5J

If she uses a force of 5N to lift 150 pounds to a height of 1.5m, the work done will be 7.5J

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
