A 3220 kg truck is rolling down a frictionless 8.30° slope that is 22.0 m long. If its initial speed was 4.71 m/s, how fast is it going at the bottom? (Unit = m/s)​

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
