A particle (m =9 mg, q = -4 pC) is moves in a uniform electric field of 23 N/C inlthe positive x direction. At t = 0, the particle is moving 46
m/s in the positive x direction and is passing through the origin. How
far is the particle from the origin at t = 4 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!
