Answer:
C
Explanation:
because it not running will set it off course but running all the time it will run. out of fuel
As we know that mechanical advantage is defined as the ratio of output force and input force for the pulley system
Here we know that it required 10 lb of input force in order to lift the block of 500 lb so here output force is 500 lb
now we have

here we have


now from above formula we have


so mechanical advantage of this system is 50
Answer
given,
V = 2 L
the left is an ideal gas at P = 100 k Pa and T = 500 K
mass is constant


Pressure is same because it's not changing due to process






m = 1.39 x 10⁻³ Kg


fusion is when solid changes it's state to liquid
and vaporization is when liquid changes it's state to gas
so the difference between fusion and vaporization is the state
