a student is conducting experiments with a block of wood. in experiment 1, the student pulls the block of wood with a constant force of 10 N along a horizontal surface. in experiment 2, the student pulls the same block of wood with a constant force of 10 N. the type of surface is different from that used in experiment 1. which surface creates more friction with the wood block

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!
