Two students try to move a heavy box. One pushes with the force of the 20N while the other pulls with a force of 30N in the same direction. What is the work done by each boy after 10 seconds if the box can\t be moved? Show your equation.
1 answer:
Answer:
Explanation:
Time is not part of the Work equation. That's the only conclusion that you can come to.
Work = Force * distance.
Not enough information is given to go any further. You don't have enough information to calculate the distance.
We don't know if the box can be moved or not. It says heavy. 50 N is really not very much.
I would guess that you are intended to answer that the box didn't move, but it's really hard to tell.

Answer:
reflection :
angle of reflection and angle of incidence is equal Incident ray and reflect d ray plus normal lies on the same plan on a same point light reflect uniformly if it is incident on a plan surface refraction :
light will refrect if light goes from rare medium to a dense medium or vice versa after the light is refracted, it retunes to its original direction angle of incidence is not equal to the angle of refraction
