When air expands adiabatically (without gaining or losing heat), its pressure P P and volume V V are related by the equation P V 1.4 = C PV1.4=C, where C C is a constant. Suppose that at a certain instant the volume is 450 cm 3 450 cm3 and the pressure is 80 kPa 80 kPa and is decreasing at a rate of 10 kPa/min 10 kPa/min. At what rate is the volume increasing at this instant? (Round your answer to the nearest whole number.)

Need in all of themmm only answer if you know plsssss

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

The two stars in a certain binary star system move in circular orbits. the first star, alpha, has an orbital speed of 36 km/s. the second star, beta, has an orbital speed of 12 km/s. the orbital period is 137 d. a) what is the mass of the star alpha? b) what is the mass of the star beta?
