For the wave of light you generated in the part b, calculate the amount of energy in 1.0 mol of photons with that same frequency (6.8×109 hz ) and wavelength (0.044 m ). recall that the avogadro constant is 6.022×1023 mol−1. express the energy in joules to two significant figures.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
