Speed = distance/time
speed= 122÷27=4.52m/s (3sf)
Answer:
The magnitude of the electric force between the to protons will be 57.536 N.
Explanation:
We can use Coulomb's law to find out the force, in scalar form, will be:
.
Now, making the substitutions
,
,
,
we can find:
.
.
Not so big for everyday life, but enormous for subatomic particles.
I would say your answer is B- Some of the chemical energy from the batteries is converted into heat energy.
