Atest tube is in uniform circular motion in a centrifuge, which is a piece of scientific equipment used to separate solids from liquids by spinning its contents very quickly. the velocity of the test tube a. does not change. b. is constantly changing. c. depends on the mass of the centrifuge. d. is perpendicular to the direction of motion.
plsss

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

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!
