PLEASE HURRY Your brother pulls up to a corvette at a stop light and revs his engine. When the light turns green he slams the gas pedal to the floor. He begins at 9km/hr and after 6 seconds is going 82Km/hr. What was his acceleration rate? (Hint: your label with be Km/hr/s)

What are the three ways that an object can accelerate

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

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.
