Agolf club (mass 0.5kg) hits a golf ball (mass 0.03kg) with a constant force of 25n over a time of 0.02 seconds. what is the magnitude of the impulse delivered to the ball? select one: o a. 0.05 ns b. 1250 ns c.1.67 x102 ns d.12.5ns o e.8.00 x 104 ns

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
