Answer 2

1. Option-(A): Electrical energy runs through a wire to a 60 Watt bulb producing light.
2. Option-(A): The ability to do work.
3. Option-(B,C): Energy is the force used to move an object, and Energy is required to set an object in motion.
4. Option-(B): You predominantly use vector quantities.

Step-by-step explanation:

Energy:

The basic capacity or the element which is required to transfer the amount of data or the information or any sort of elements from the point of generation to the point of destination is called as the energy.

While, the Energy,E is basically the concept of storing the amount or level of capacity inside a source or it can be transferred from the point of generation to the point of its source or destination. It is a scalar quantity just because the two vector quantities the time,t and the force,F gives rise to the scalar quantity known as the energy,E.

The energy,E is transferred from one point to another.While, each object in this universe has some mass,m while the objects can be moved from one point to another when the energy,E stored inside the object is transferred from its stored form into motion.
