the answer to your question is 15 :)
Answer:
0.712 mH
Explanation:
The emf produced by the coil = 2.6 V
Current is changes from -29 mA to 33 mA so change in current di =33-(-29)=62 mA
The time duration that is dt=17 ms
The emf is given by
So the value of inductance will be 0.712 mH
We should really talk about the energy of a photon.
Photon Energy= h x c/ wavelength
where h is Planck's constant and c is the speed of light
h = 6.63 x 10^-34
c =3x 10^8
Energy = 2.37 x 10^-21
Answer:
Chloroplasts convert light energy into sugars that can be used by the cells. This conversion creates 'food' for the plant.

Answer:
You are correct, it is (3) the ball is in motion as it rolls down the slope.
Explanation:
For number 1 it would make sense because how would the student be in motion if he is just standing there throwing the ball down the slope, not himself.
For number 2 still wouldn't make so much sense since we are talking about the ball being in motion not the student.
For number 3 it seems the most reasonable because the ball is in motion as it is rolling down the slope.
For number 4 it doesn't make sense for a ball to lose its shape just by rolling, also even if you're like: "oh, but what if its leaking air or has a hole??" well easy then. It STILL wouldn't matter because in the sentence it never specifies it has a "hole" or is "leaking air" therefore this answer is wrong.
YOUR ANSWER IS number 3.
