in equation my"+cy'+ky=r(t), let m=1g, c=0.02g/s and k =25g/s so that the equation becomes y"+0.02y' +25y=r(t)​

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!
