<span>A coil of current - carrying wire that produces a magnetic field is called a solenoid. An ? is a solenoid with a ferromagnetic core. ?, a device that uses a solenoid to measure small amounts of current. An ? motor is a device that uses an electromagnet to turn an axle.</span>
Elastic Potential Energy because the elasticity in the string stores up the energy.
Density is varying through the world’s oceans. The density of ocean water is not uniform.
Answer:
a) The force is zero, or the displacement is zero, or the angle is 180 degrees
b) The kinetic energy, speed, and velocity of the particle change.
c) W1 = - W2
Explanation:
In science energy is simply defined as the ability to do work. Anything that causes work to be done must have expended some form of energy .
Energy is broadly categorized into two parts;
- Kinetic energy is the energy due to the motion of a body.
- Potential energy is the energy at rest in a body.
- Other forms of energy stems these two forms of energy.
- Thermal energy, mechanical energy are examples of kinetic energy.
- Chemical energy, gravitational energy are examples of potential energy.
- Energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
