A 60-kg man standing on a scale in an elevator notes that as the elevator rises, the scale reads 818 N. What is the acceleration of the elevator

Explanation:

Given that,

The mass of a man, m = 60 kg

When the elevator rises, the scale rads 818 N

We need to find the acceleration of the elevator. Let it is a. The equation of motion can be written as :

F - mg = ma

Put g = 9.8 m/s²

So, the acceleration of the elevator is

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.
