The figure below shows a 2 kg box. A 10 N force pushes the box horizontally across a level flat surface. The frictional force that results from contact with the surface produces a 2 N force that opposes the direction of the box's movement. image What is the net force acting on the box? A. 5 N, right
B. 8 N, right
C. 20 N, right
D. 12 N, right

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!
