A50 kg skydiver is falling downwards and accelerating 6 m/s2 down. what is the net force on the skydiver?

300 n, up
8.3 n, down
300 n, down
500 n, up

Net Force = (mass) x (acceleration)  (Newton #2)

Net Force = (50 kg) x (6 m/s² down)

Net Force = (50 * 6) (kg-m/s² down)

Net Force = 300 Newtons down

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.
