Skye is trying to make her 70.0-kg Saint Bernard go out the back door but the dog refuses to walk. If the coefficient of sliding friction between the dog and

the floor is 0.50, how hard must Skye push in order to move the dog with a

constant speed?

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
