Answer:
I'm pretty sure it's 3.
Explanation:
Because if you look at your options the only that would be relevant to tick marks would be either 4 or 3. And it said in the question that we're looking for the one for the dependent variable. And the dependent variable is on the Y- Axis and the 3 is the tick marks for the y-axis. So your answer is 3.
The force exerted on the rope of the pulley system if the rope is pulled for 24 m in order to raise the mass to the required height is 81.6 N
<u>Explanation:</u>
Efficiency, γ = 64%
mass, m = 78 kg
height, h = 4 m
Force, F = ?
distance of the rope pulled, x = 24 m
We know,
Acceleration due to gravity, g = 9.81 m/s²
Potential energy, PE = mgh = (78) X (9.81) X (4) = 3060.72 joules
Work, W = F X x
F = W/d = (3060.72) / (24) = 127.53 N
However, the efficiency of the pulley system is 64%.
The real force required is F(net) = (127.53) X (0.64) = 81.6 N
Therefore, the force exerted on the rope of the pulley system if the rope is pulled for 24 m in order to raise the mass to the required height is 81.6 N
Answer: what does this even say?

D.)</h2>
Explanation:
Potential energy is when a object is not in motion and the ball is sitting on a shelf not being thrown around or rolling. kinetic energy is when a obeject is in motion and moving.
