Answer:

Explanation:
As we know that the current through the battery is given as

here from above equation we know that current will become zero when time elapsed is very large
so here we can say that charge will flow through the battery from t = 0 to t = infinite
now we have





As we know that

Answer:
The toy car
Explanation:
the real car is parked so yeah but maybe in some way technically the real car has more "momentum"
The reason why Kim's hair rises and sticks out is due to electrostatic attraction.
<h3>What is charging by friction?</h3>
We know that one of the ways in which a body is able to acquire static charges is by friction. When a body is rubbed against another, there could be loss or gain of charges leaving a net charge on each body.
The process that occurs when some of Kim's hair rises and sticks out toward the balloon, even though the balloon hasn't touched her hair is electrostatic attraction.
