Ameteorologist tracks the movement of a thunderstorm with doppler radar. at 8: 00pm the storm was 55 mi northeast of her station. at 11: 00 pm the storm is at 75 mi north. what's the direction of the average velocity of the storm? and the magnitude of the average velocity of the storm?

The midpoints? a, b, and c are marked on the histogram. match them to the indicated scores. which? scores, if? any, would be considered? unusual?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

The air that we breath is made mostly of which gaseous molecule
