Answer:
Centripetal force..
Explanation:
Centripetal Force
There is a force that pushes you towards the center of the circle / curve (towards the left). This is the force acting on you which keeps you inside the car. This is the Centripetal Force. Because of the law of forces, If a force is applied on you, you apply an equal and opposite force against that.

Explanation:
32. The area under the curve from t = 0 and t = 2 is the area of the triangle. The base of the triangle is 2 seconds, and the height of the triangle is 2 m/s. The area is therefore:
A = ½ bh
A = ½ (2 s) (2 m/s)
A = 2 m
33. The car is not moving when the velocity is 0 m/s. This occurs at t = 0, t = 6, and t = 10.
The average walking speed for an adult would be around 6 m/s, and average leght of adult human legs is around 1m so the best answer of the given answers would be 7.9 m/s
Question :
If a body acquires a charge of -0.02 C, has it gained or lost electrons? Many?
Solution :
We know, charge gained is shown by negative sign.
Since, charged acquired is given as -0.02 C .
Therefore, it is body has gained electrons.
Now, number of electrons is given by :
Hence, this is the required solution.
