The note created by a flute will increase 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.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
