The speed of a note created by a flute will increase as the speed of sound increases. when a marching band goes outside on a cold day, what would you predict would happen to the note played on a flute?
a) it would decrease because the speed of sound and temperature are proportional.
b) it would increase because the speed of sound and temperature are proportional.
c) it would decrease because the speed of sound and temperature are inversely proportional.
d) it would increase because the speed of sound and temperature are inversely proportional.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
