For an electromagnetic wave described by b = 8 × 10–6 sin(5000πx – 3 × 1011πt), where b is in tesla, x is in metre and t is in second, the incorrect parameter is.

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!
