Aradiograph made using 300 ma, 0.1 second, and 75 kvp exhibits motion unsharpness, but otherwise satisfactory technical quality. the radiograph will be repeated using a shorter exposure time. using 86 kv and 500 ma, what should be the new exposure time? (a) 0.12 second (b) 0.06 second (c) 0.03 second (d) 0.01 second

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

It is really hard for me right know

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!
