Tori experiments with pulleys in physics class. She applies 70 newtons of force to a single pulley to lift a bowling ball. By adding another pulley, she’d get a mechanical advantage of 2. What’s the minimum input force she’ll need to lift the ball if she adds another pulley? A.
2 N
B.
35 N
C.
68 N
D.
70 N
E.
140 N

c

Explanation:

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

this is a good question! i'll do some research and come back when i have the answer!
