Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Answer:
The time is 2.8 ms.
Explanation:
Given that,
Capacitor = 0.12 μF
Resistance = 10 kohm
Voltage = 12 V
Charge Q = 0.9 Q₀
We need to calculate the time constant
Using formula of time constant
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 2.8 ms.
So picture below to see answer and explanation.
Answer:
Option B is correct
Explanation:
Motion is described with respect to frame of reference.
A frame of reference refers to a set of coordinates that helps to find positions and velocities of objects in the frame.
The laws of motion might be more complex than required if the coordinates are not chosen properly.
Therefore,
Option B is correct
