Torque due to gravity can be correctly calculated by pretending that all of the mass of an object is concentrated at: a. the object's center of mass
b. the lowest point on the object
c. the highest point on the object
d. the heaviest piece of the object

The plum pudding model of the atom state that ?

Which notation is used to represent an alpha particle? a. b. c. d.

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,?
