Which statement can be made about both waves? Sound Wave Ais moving through a medium that is decreasing in temperature. Sound Wave B is moving from a liquid to a gas medium. O They will speed up. O They will increase the density of their medium. They will slow down. O They will decrease the density of their medium.​

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
