Subtracting 2 Vectors
This is where things obtain a bit more interesting. What we required to note here is in which in Physics a negative sign simply means "in the opposite direction." We can take A - B and simply modify it into A + -B. The negative sign on the B just means that we will require taking the original vector B and pointing it in precisely the opposite direction (180° from where it's pointing right now. Then we will easily add them just such as we did in the previous diagrams (touching head-to-tail of course!)
Explain quasi-static isothermal expansion A method is reversible only if it is quasi-static and non dissipative. E.g. A quasi-static isothermal expansion of an ideal gas

A 2350-kg granite tombstone absorbs 2.8 x 107 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day.
Differentiate between Fraunhofer's and Fresnel's type of diffraction?
A wave front is a line or surface on which the disturbance has the similar phase at every position. If the source is periodic, it generates a succession of ray front, each of the s
