A body is resting on a plane in client at angle of 30 degree to the horizontal what force would be required to side it down if the coefficient of friction between body and plane is 0.3 degree our? 5 kilogram 1 kilogram 0r would depend on weight of body

Why is there friction between objects

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

Ais not a compound machine. a. bolt b. shovel c. handcart (dolly) d. see-saw (teeter totter)
