Increasing the engine's operating temperature, reducing the efficiency of the heat exchange process, and using poor quality fuel can all contribute to more wasted energy being released as heat in a heat engine. Additionally, increasing the friction in the engine's moving parts can also lead to more energy being lost as heat.

What is the efficiency of a car's engine when he input is 20000 joules and the waste heat is 15000 joules?

The efficiency of the car's engine is calculated by dividing the useful energy output by the energy input. In this case, the useful energy output would be 5000 joules (20000 input - 15000 waste heat), thus the efficiency would be 5000/20000 = 0.25 or 25%.


Which engine wastes the most energy?

I would say, heat engine on earth would waste the most energy since it is always limited by thermodynamic efficiency to have some loss. In general, lower the temperature difference will resulted to lower the efficiency, a simple steam engine for a train would be of lower efficiency than a internal combustion engine and lower than complex high pressure steam turbine and is probably the lowest engine efficiency in commercial scale.


What is the efficiency of a cars engine when he input is 200 million Jules and the waste he is 1150000 jewels?

The efficiency of the car's engine is calculated by dividing the useful energy output by the total energy input. In this case, the useful energy output would be 200,000,000 J - 1,150,000 J = 198,850,000 J. Thus, the efficiency would be (198,850,000 J / 200,000,000 J) * 100 = 99.43%.


What is the effiency of a cars engine when heat input is 400000 joules and the waste heat is 300000 joules?

The efficiency of the car's engine can be calculated using the formula: Efficiency = (Useful energy output / Total energy input) x 100%. In this case, the useful energy output is the heat input minus the waste heat: 400000 J - 300000 J = 100000 J. Therefore, the efficiency would be (100000 J / 400000 J) x 100% = 25%.

What would be considered a living thing?

Something is alive if it can reproduce, respond to changes in its environment, can convert some form of energy into energy to sustain its self, and produces waste.

How is energy not wasted?

Energy is wasted through activity so I guess not doing anything would not waste energy but it is hard to not waste any energy at all


What would happen if you do not conserve energy?

When you waste energy,during night time, no one would se anything

Can v use lasers in destroying nuclear waste?

No, lasers would not cause nuclear changes, they would only melt or vaporise material which is not what is wanted. The nuclear properties of the waste would remain the same.
