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.
Answer:
Time=8.23880597 seconds
Explanation:
Quantity of charge(q)=2.76c
Current(I)=0.335A
Time(t)=?
t=q/I
t=2.76/0.335
t=8.23880597seconds
Answer:
Should be moving away
Explanation:
Red is a longer wavelength therefore further away. Wavelength is stretched out more and on the red end. I hope this is right. I decided to research and answer since you didn’t have other answers. Are you taking this on edg? I hope I helped!
Force. Force is measured by newtons, probably because he came up with the equations to calculate force.
Hope this helps!
