If the sum of both the external torques and the external forces on an object is zero, then the object must be at rest. true or false

False

Explanation:

The object could be in a constant velocity and the sum of both the external torques and the external forces on an object is zero. Newton's first law states that when the total net force is 0 or there is zero force, the object could be at rest OR remain in constant velocity. It's not necessary at rest.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
