Answer:
Mechanical energy into electrical energy
Explanation:
The dependent variable was the time and the independent variable was thecars
Answer:
Yes – its direction is changing.
Explanation:
It is given that, a car rounds a curve while maintaining a constant speed. We know that on a circular curve, the object moves with constant speed. The velocity of object keeps on changing due to change in its direction. Here, the forces acting on the car are force of gravity and the centripetal force.
We can say that yes there is a net force on the car as it rounds the curve due to the change in its direction of motion. Hence, the correct option is (3).
