NEED ASAP!! A box weighing 30 N is on a horizontal floor. The coefficient of static friction is 0.30 and that of kinetic friction is 0.25. Find the frictional force under the following conditionsa) no additional forced is added, b) a force of 5 Nis applied to the east, c) a force of 9 N is applied to the west, ) a force of 10 N is applied to the south.

State the right hand rule of the direction of magnetic field in a conductor carrying current

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

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?
