At a standard temperature, a pressure that is 0° C and 1.01 x 105 Pa pressure, the density of oxygen is 1.43 kg m-3.
Oxygen is stored in a container of volume 3.87 m3 at a pressure of 2.02 x 105 Pa at a temperature of 25°C.
i. What volume would the same mass of oxygen occupy at a ‘standard
temperature and pressure’? calculate the mass of oxygen in the container.

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
