Answer: velocity = -0.65 speed =0.65
Explanation:
Velocity =speed+direction speed =distance/time
12 V is the f.e.m.

of the battery. The potential difference that is applied to the motor is actually the fem minus the voltage drop on the internal resistance r:

this is equal to the voltage drop on the resistance of the motor R:

so we can write:

and using

and

we can find the current I:
Answer:isotopes
Explanation:Isotopes form when the number of neutrons and atomic number change except for the protons don't change
If it is stationary, its not moving. there is no movement
The shape of which the pebble sized particles that makes up the rock is more of a rounded shape as they are bits and in circular formation, depicting it to be more rounder in which are particles that is made up in a rock. They can be in pebble sized or much more smaller than that when in bits.
