@ganeshie8 @Mashy @ikram002p

Answer 2

I would think positive

Answer 3

please explain it little :/

Answer 4

well you pulling it up so you are adding to the force and adding is positive and when you were to like drop it that would take some of the force you are using away so then that would be negative

Answer 5

ok thank ya so much ^_^

Answer 6

NP

Answer 7

but this show
Typically, we have to push down the rope and direct our force downwards hence the bucket lifts up. Since the force and direction of displacement is anti-parallel to each other, angle between them is 180.

F.d = FdcosQ
F.d = - Fd.

Answer: NEGATIVE!
is that correct ???

Answer 8

Anything else

Answer 9

Yes I would guess since it says so but IDK

Answer 10
