Calculate the work done by a person who exerts a force of 200.0 N in the horizontal direction on a box that moves 10.0 meters along a ramp that makes an angle of 30.0o with the horizontal, moving the box at a constant speed. Note: Do not include the work done on the person, only on the box.

the work done by a person is 1,732 J

Explanation:

The computation of the work done by a person is as follows;

The following information is given

Force = 200.N

Distance = 10.0 meters

Angle = 30 degrees

based on the above information

Work done is

Work done is

= (200) (cos 30 degrees)  (10.0 meters)

= 1,732 J

hence, the work done by a person is 1,732 J

The same is considered and relevant

it becomes positively charged by charging it

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
