a system absorbs 35J of heat and in the process it does 11J of work if the initial internal energy is 205J a, what is the final internal energy b, the system follows a different thermodynamic path to the same final state and does 15J of work, what is the heat transferred ?

terd muffin is the correct answer

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
