Wanda and marita are drinking bottles of water. each girl sounds a different musical note by blowing across the top of her bottle. what is a good hypothesis that could lead to new experimentation? it is more fun to play musical notes with carbonated water than with normal spring water. if the lid on a bottle is tightly closed, then blowing across the top of the bottle will not make a musical note. blowing across the top of a bottle can make a musical note. if there is less water in the bottle, then the note played is lower because there is more air to move around.

ITS NOT C!

its actually D.If there is less water in the bottle, then the note played is lower because there is more air to move around.

D

Explanation:

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
