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
The relationship between the initial velocity, final velociy, distance, and deceleration can be expressed in the following equation.
2(a)(0.270 m) = 0² - (5.70 m/s)²
The value of a (which is the deceleration) is 0.06 m/s². Thus, the answer is that the deceleration value is approximately 0.06 m/s².
because its has energy and uses it natural energy from the ground
B is the answer
Explanation: look at the graph
Since the force acting is two dimensional, resolve it along the horizontal surface and perpendicular to the surface by using *resolution of vectors*
