Student while doing an experiment finds the work done by an object varies with displacement s and it can be expressed as equation: W=XS^2+YS+Z
if units of W and S are expressed in terms of SI units ,determine the units of constants X, Y and Z in the given equation.​

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!
