An object moving in a circle at a constant speed is accelerating. why?
a. because it is going faster
b. because it has constant velocity
c. because its direction is changing
d. because the distance it is traveling is changing

When fat comes in contact with sodium hydroxide, it produces soap and glycerin. determine whether this is a physical change or a chemical change. explain your answer

If the speed of a particle triples ,by what factor does its kinetic energy increase?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
