12. A conducting 41.0 cm long rod makes contact with two metal rails which are fixed. There is a uniform magnetic field of 14.0 T that is directed out of the page as shown in the figure. What is the magnitude of the induced emf and the
direction of the induced current when the rod is moving at a speed of 3.15 m/s?

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 equation2: 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!
