Knowing the force and distance allows you to calculate the work done.
Then, if you know the TIME, you can calculate the power.
Answer:
Gamma rays have the highest energies.
Explanation:
HOPE IT WILL HELP ^_^
Answer:

Explanation:
First, we write the equations of motion for each axis. Since the crate is sliding with constant speed, its acceleration is zero. Then, we have:

Where T is the tension in the rope, F is the force exerted by the first worker, f_k is the frictional force, N is the normal force and mg is the weight of the crate.
Since
and
, we can rewrite the first equation as:

Now, we solve for
and calculate it:

This means that the crate's coefficient of kinetic friction on the floor is 0.18.
That's true.
I have a hunch that there definitely IS a change of phase at every reflection.
The answer is: "isotopes" .
