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?

god i hope this !

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
