For a chair to be balanced on one leg, where must the center of gravity be located? A. in the center of the seat B. toward the front of the chair C. toward and above the balancing leg of the chair D. toward the back of the chair

The correct answer is c

Explanation:

When a body is in rotational equilibrium, the relationship must be met

     ∑ τ = 0

     Σ F d = 0

therefore the forces that are exerted on the body that are represented in the center of gravity are different from zero, therefore, to maintain balance the distance must be zero, therefore the center of gravity must be above the leg where the body is balancing

The correct answer is c

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.
