Answer: all the energy is rushed in the wires due to the swich turning on when touching it may start a fire or electricute
Explanation:
fs
Option C
The fact that voltage can be created by exerting force on a crystal is used in Knock sensor
<u>Explanation:</u>
Any knock to an engine exhibits as a little shake that is distinguished by the knock sensor. This sensor acts by altering the fluctuation to an electrical sign, which is later transferred to the processor mastering the ignition system.
There the variation in quake to the voltage sign modifies the timing improvements on the kindling. The knock sensor is placed on the engine base, cylinder cap or consumption manifold. This is because its purpose is to sense fluctuations affected by engine knock or explosion.
Answer:Free-moving Electrons
Explanation:
In metals which are good conductor of heat and electricity metals are free to move.This facilitate the conduction of heat and electricity through them.In both case delocalised electrons is responsible for conduction as they are not firmly attach to particular atom and are free to move.
Heat conduction is due to vibration of ions in the lattice, at heated end ions vibration is much more as compared to cold end and this vibration passed on to heat the metal.
Answer:
C. The sum remains the same.
Explanation:
The sum of the kinetic and potential energy remains the same as the all rolls from point A to E.
We know this based on the law of conservation of energy that is in play within the system.
The law of conservation of energy states that "energy is neither created nor destroyed within a system but transformed from one form to another".
- At the top of the potential energy is maximum
- As the ball rolls down, the potential energy is converted to kinetic energy.
- Potential energy is due to the position of a body
- Kinetic energy is due to the the motion of the body
