Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.
Displacement:
It is a vector quantity that is defined as the overall change in the position of the object.
The formula for displacement is:
Where,
- total displacement
- final position
- initial position
In the given graph:
- Car displaces 15 km in 2 hrs
- Car displaces 20 km in 4 hrs.
- The car moves back to the initial position in 5 hrs.
Therefore, the displacement of the car in 5 hrs is 0 km.

Where’s the picture of the problem
Answer:
C is the right answer.
Body massager uses electrical energy to move back and forth. In this sense, a motor is being used for the operation
a.the amount of sunlight increases.
Explanation:
As a submarine rises to the surface, the change it encounters that is true from the given options is that the amount of sunlight increases.
The bottom of the ocean is dark and receives little to no sunlight due to the scattering of the rays by ocean water.
- As the submarine rises, the volume of water column on it decreases and the pressure on it decreases too.
- Also, the temperature rises steadily to the surface.

Both the velocity and acceleration are vector quantities. It means that this parameter does not only have magnitude, but also the direction of motion. The direction is incorporated by the + or - sign depending on the sign convention. In this case, the downward motion is + while the upward motion is -. Thus, the velocity is equal to +0.89 m/s while the acceleration is -2.92 m/s².
