Answer:
C) Emf is the force exerted on a single charge to move it from one terminal to the other of an emf device.
Explanation:
Electromotive force, abbreviation E or emf, electrical energy per unit supplied from an energy source, such as an electrical generator or a battery. In the engine or battery, electricity is transformed from one source to another as the device works on the electrical charge that is passed within itself.
In physics it is defined as Work done by a cell or battery in moving a unit charge from its one terminal to the other, against the potential.
Hence C is correct
Answer:
Uniform circular motion
Explanation:
When a car is moving with constant speed along a curve, it will said to have uniform circular motion. The speed of the car remains constant in this case. But its velocity keeps on changing. The velocity can be calculated by drawing the tangent on the circle. Hence, the motion of the car is uniform circular motion.
