nazli's father buys a bar fridge with a mass of 30kg. he unloads the box containing the bar fridge and starts to push it towards the house. at first he has to push with a force of 135 N to get the box to start moving. once it is moving he has to exert a force of 120 N to keep it moving with a constant speed. for the box on the driveway, calculate the maximum coefficient of static friction?​

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

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.
