Awooden box weighing 150 n is sliding at a constant rate over a concrete sidewalk. the force required to pull the box at a steady rate is 78 n. what is the coefficient of friction?

The coefficient of friction is 0.52

Explanation:

Weight of the box, W = N = 150 N

The force required to pull the box at a steady rate is 78 N, F = 78 N

In horizontal direction, the net force acting on the box is given by :

So, the coefficient of friction is 0.52. Hence, this is the required solution.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
