a)2 joules

b)10 joules

c)18 joules

d)80 joules

Respuesta :

Answer:

d)80 joules

Explanation:

Given that

Distance to move ,d= 8 m

Applied force ,F= 10 N

As we know that work done by a force to move a object distance d given as

W = F .d

Now by putting the values in the formula

W= 10 x 8 N.m

W= 80 N.m

We know that 1 J = 1 N.m

Therefore we can say that

W= 80 J

Therefore the answer will be d

d)80 joules

Answer:

80 joules or d

Explanation:

Work/joules= force times length. Hope this helped. thanks! :)
