Ihave an astronomy spinning up the solar nebula. the orbital speed of the material in the solar nebula at pluto's average distance from the sun was about 5km/s. what was the orbital speed of this material when it was 40,000 au from the sun (before it fell inward with the collapse of the nebula)? use the law of conservation of angular momentum. i have the angular momentum = m x v x r. is this correct?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
