Answer:
The workdone by Jack is
The workdone by Jill is
The final velocity is
Explanation:
From the question we are given that
The mass of the boat is
The initial position of the boat is
The Final position of the boat is
The Force exerted by Jack
The Force exerted by Jill
Now to obtain the displacement made we are to subtract the final position from the initial position
Now that we have obtained the displacement we can obtain the Workdone
which is mathematically represented as
The amount of workdone by jack would be
The amount of workdone by Jill would be
According to work energy theorem the Workdone is equal to the kinetic energy of the boat
Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
