Three dogs are pulling on a peg. Two are pulling in the same direction with forces of 85 N and 65 N, respectively. The third dog is pulling in the opposite direction with a
force of 70 N. What force does the peg need to resist to keep from being pulled out?
Show your reasoning.

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,?

What characteristics of hv2112 make it the best candidate to be classified as a thorne-zytkow object?

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation
