It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.
To Build The Motor, Faraday Studied Electricity And Magnetism. Hope This helps!
It will be approximately equal.
<h3>How will the final kinetic energy change?</h3>
We can infer that all of the energy in the electron is Potential energy (PE) because the energy provided by the photon is hardly enough to outweigh the work function.
It will gain kinetic energy (KE) as it advances in the direction of the anode because it is moving through an electric field. All of the PE will have been transformed to KE by the time it reaches the anode.
According to the question
K = hf - W
W = Work function
The energy of photons is comparable. After conversion, there was only a little amount of KE remaining.
Therefore, PE (W) essentially equals KE (K).
It will about be equal.

#SPJ4
The cat fell 1.0 m from the ground.
Using the formula
Here, 
Solving for t, the time it spent in the air is
The cat does not accelerate along the horizontal, so it has constant horizontal velocity. Since it strikes the floor 2.2 m from the table, then
Answer:5.60 m/s
Explanation:
Given
Coefficient of static friction 
Coefficient of kinetic friction 
mass of crate 
Force applied 
maximum static Friction 
thus applied force is greater than Static friction therefore kinetic friction will come into play
net Force on crate 
Magnitude of velocity can be obtained by using
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
here initial velocity is zero as crate start from rest
