A sample of gas has an initial volume of 30.8L and an inital temperature of 67-degree celsius. what will be the temperature of the gas if the volume is 21.0L? (please show working)

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?
