The energy is 3.06 electronvolts, E = 3.06eV
1eV = 1.6 * 10^-19 J
3.06 eV = 3.06* 1.6 * 10^-19 J = 4.896 * 10^-19 J
Answer:

Explanation:
When two cars collide then the momentum of two cars will remains conserved
- Mass of two cars = 100 kg
-
Speed of car B = - 10 m/s
-
After collision the speed of car B = +8 m/s
By momentum conservation equation


Because when your running any experiment there will always be an experimental error so always be ready for it so that you can correct that error in your experiment
added to the engine minus the waste heat
Explanation:
The amount of work done by a heat engine equals the amount of thermal energy added to the engine minus the waste heat.
Thermodynamics is used to measure the energy changes that accompanies physical and chemical process.
In a system;
Internal energy = Quantity of heat added - Work done on it
internal energy is designated as ΔU
quantity of heat as Q
work done as W
ΔU = Q - W
so W = Q - ΔU
some of the heat added added to the system goes as waste heat as no system is 100% efficient.
the work done on a system goes in as thermal energy, internal energy and waste heat
