it the tv is on and showing screen or on standby the tv will use power. however in standby mode the tv is supposed to use a reduce power ratio

No. Total energy is always conserved, but not so mechanical energy.

In a collision what is conserved?

Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.


The total amount of energy before and after a chemical reaction is the same .Thus energy is what?

Therefore energy is conserved.

Not really, no.


Which is not conserved mass acceleration energy momentum?

Acceleration is not conserved. Energy can not be created nor destroyed. Mass and momentum are both conserved through a set time.

How does energy is conserved in a transfermation of energy?

Energy is neither used up nor destroyed, but it is converted into something else. In that way, it is conserved.


How can tidal energy be conserved?

Tidal Energy can be conserved by using offshore turbines rather than underwater turbines.


How can energy be conserved from a nuclear weapon?

A tiny bit of the mass of each fissioned (or fused) atom is converted to energy. Energy is not conserver... Mass-Energy is conserved.


Is potential energy conserved or not measurable?

It is not conserved. Total energy is conserved, but specific types of energy are usually not conserved. Not sure what you mean by "measurable" - potential energy is usually calculated, on the basis of other quantities. For example, in the case of gravitational potential energy, PE = mgh (mass x gravity x height), all of which can be measured.
