  1. 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?
    =====================
    600/50 = 60/5 = 12
    ===================

    A. 650.0 (I PICK THIS)
    B. 8.3
    C. 12.0 <---------------- MY CHOICE
    D. 0.0833

    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%
    ===================

    A. 82.7 percent <------ MY CHOICE
    B. 121.0 percent(I PICK THIS)
    C. 32.0 percent
    D. 338.0 percent

  81. @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!
