Block a on the left has mass 1.00 kg. block b on the right has mass 3.00 kg. the blocks are forced together, compressing the spring. then the system is released from rest on a level, frictionless surface. after the blocks are released, how does ka (the kinetic energy of block a) compare to kb (the kinetic energy of block b)?

J. j. thomson’s experiment disproved the theory that an atom

Which of these is constant for all types of electromagnetic radiation in a vacuum? select one: a. wavelength b. frequency c. photon energy d. amplitude e. velocity

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!
