The commutator of two operators a and b is defined as [a, b] = ab-ba. a) given the operators a = a+bx and b=d/dx, calculate [a, b]f(x). b) do a and b commute?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
