Carbon monoxide is a gas at 0 °C and a pressure of 1.06 × 105 Pa. It is a diatomic gas, each of its molecules consisting of one carbon atom (atomic mass = 12.0 u) and one oxygen atom (atomic mass = 16.0 u). Assuming that carbon monoxide is an ideal gas, calculate its density ?
There is an 80 kg beam attached to a hinge on a wall and supported by the cord. The angle between the cord and the beam is 25 degrees. The beam is 4.5 m long., and cord is attached to the beam a metre from the beam's end. There is a 20 kg beam hangin..
