As a skydiver with a mass of 54 kg falls toward the Earth, she accelerates at 9.8 m/s2. What is the force of
gravity acting upon the skydiver? What must be true about the force of air resistance acting on the skydiver?

B. The force due to gravity is 530 N. The force of air resistance is less than the force due to gravity.

Explanation:

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.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
