ILL MARK YOU THR BRAINLIEST SOMEONE PLS HELP ITS URGENT. The acceleration of a skydiver of mass 80 kg changes from 9.8 m/s ^ 2 to 5.8 m/s ^ 2 as he falls through the air. What is the air resistance experienced by him?

320N

Explanation:

Net force =w- AR

AR=w -force

AR=mg- ma

AR=80*9.8- 80*5.8

AR=784- 464

AR=320N

like poles repel so keep pushing north to north and repels funny to see this

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.
