Explanation:
It is given that,
Charge in the particle, 
Work done by the force, 
The kinetic energy of the particle, 
(a) Using the conservation of energy to find the work done by the electric force. Let it is given by 
as :
(b) Let V is the electric potential. the work done by the electric charge per unit positive charge is called its electric potential. Mathematically,
Hence, this is the required solution.
More work was done in the skateboard that came to a stop because the one that rolled across the room moved on a surface with less friction while the second board used more work to move on a surface with much friction.
my answer is 1276.7 because I subtracted 88.3 miles and seconds from 1365 MI
PART A)
Equivalent resistance in parallel is given as
now we have
PART B)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law
As we know i = 7 A current flows through 15 ohm resistance
PART C)
Similarly ohm's law for 20 ohm resistance we can say
