Question 1

An object of mass m is suspended by two coplanar wires, as shown below. The tension in each wire has a magnitude given by



.

.

.

mg.

.


Question 2

Angie says that an object is in equilibrium if the net torques about the center of mass is zero. Robbie says that an object is in equilibrium if the sum of external forces is zero. Which one, if either, is correct?

Both are correct: an object is in equilibrium if either condition holds.

Neither is correct: both conditions must hold simultaneously.

Neither is correct: the net external force and the net external torque about any axis must be zero.

Neither is correct: an object is in equilibrium only if its velocity is zero in all coordinate systems.

Both are correct: if the sum of the external forces is zero, the net torque about any axis is automatically zero, and vice versa.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
