The energy of position, stored energy. e.g. exhibited by the position of electrons in electron shells relative to the atom's nucleus.
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

According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
Answer:
angle of incidence for the second mirror is 55.4 degree
Explanation:
Given data;
Angle between two mirror is 90 degree
Incident angle on first mirror is 34.6 degree
For first mirror
Angle of incidence is equal to angle of reflection
34.6 degree = angle of reflection

Now , for the triangle ABC [from figure]



The angle of incidence for
angle of incidence for the second mirror is 55.4 degree
