@Sharkie Kanachu Allow me! :)
1. A box of cleaning supplies weighs 15 N. if the box is lifted a distance of 0.60 M, how much work is done? Answer: B. Explanation: 15 N x 0.60 = 9 J
2. To chop wood you apply 50.0 N of force to an ax. The ax applies 600.0 N of force to the wood. What is the mechanical advantage of the ax? Answer: C. Explanation: 600.0 N ÷ 50.0 N = 12 (Or 12.0 in this case.)
3. You do 185 J of work pulling a cart up a ramp. if the ramp does 153 J of work, what is the efficiency of the ramp? Answer: A. Explanation: 153 ÷ 185 = 82.7.
The last two are pretty easy.
Number 4 is A. Obviously if you put oil on anything it won't increase friction, so B and D are out. C doesn't make much sense because if you put oil on your tires it won't make you faster, it will make you slippery.
Number 5 is very simple. A, B, and C are not simple machines, so D is the only option.
I hope this helped!
you all are lovely people. thanks salted caramel! :)

5.pulley or D
none ya is correct
Thank you everyone. NOW SHUT UP.

has died in the last twenty four hours
that person was me
JK you thought
yep they right they right

1. A box of cleaning supplies weighs 15n.if the box is lifted a distance of 0.60m,how much work is done?
===================
Force * distance
15 * .6 = 9 Joules
==========================
A. 0.040 j
B.9 j MY CHOICE
C.14 j (I PICK THIS)
D.25 j
2.to chop wood you apply 50.0n of force to an ax. The ax applies 600.0n of force to the wood. What is the mechanical advantage of the ax?

3.you do 185 j of work pulling a cart up a ramp. if the ramp does 153 j of work, what is the efficiency of the ramp?
-----------------------------
I think you have a typo in the question
If the useful work done is 153 and you needed 165 then
100 * 153/185 = 82.7%
