Physics
1 answer:
vesna_86 [32]3 years ago

Because when it had any, the warmth of the sun heated the atmosphere to the point where the average speed of the gas molecules exceeded the escape velocity for a body with the moon's mass and size. So, little by little, they escaped.

If you cannot exert enough force to loosen a bolt with a wrench, which of the following should you do?
stepan [7]

Answer:

2.) Use a wrench with a longer handle.

Explanation:

It is suggested to use a wrench with longer handle if you cannot exert enough force to loosen a bolt with a wrench.

In doing this work, the torque which is the force that can turn the screw is not enough;

      Torque  = force x distance

If we increase the distance or the length of the handle, we can generate more torque to overcome the force needed.

kirill115 [55]

<span>Efficiency is the measure of how efficient a process is. It is used to assess the ability of a process in avoiding waste energy, materials, money and time in doing a desirable output. It is calculated as;

Efficiency = useful energy ouput / total energy input</span>

<span>
.742 = useful energy / 200 J
Useful energy = 148.4 J  <-----------OPTION B</span>
