<span>The answer is: 2. 11
Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
imma tell you this i honestly dont know either i never did thi in middle school
Answer:
See below.
Step-by-step explanation:
Step 3 should be: 576pi / 64pi = 64pi h / 64pi
Step 4: 9 = h.
I would say C and D.
Step-by-step explanation:
the correct answer is C because the measurementor an angle cannot be under 72 :)
