<span>The answer is C)
mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9

Answer: 5.4
Explanation:
P2 = P1V1/V2
P2 = (.60atm x 27L) / 3.0L = 5.4atm
The peaks are there where the centre of the concentric circles lie. (Not circles exactly)
You can count a total 4 of them.
So there are a total of 4 peaks
See the attachment. I have marked them with a cross.
