A
1,100
B
24,000 J
С
110,000 J
D
240,000

Answer 1

This question involves the concepts of the work done, the force applied, and the distance moved.

The work done by Kartianna is "D. 240,000 J".

The work done can be calculated by the following formula:

W = Fd

where,

W = work done = ?

F = Force Applied = 300 N

d = Displacement = 800 m

Therefore,

W = (300 N)(800 m)

W = 240,000 J
