A disk with a radial line painted on it is mounted on an axle perpendicular to it and running through its center. It is initially at rest, with the line at (theta0) = -90°. The disk then undergoes constant angular acceleration. After accelerating for 3.1 s, the reference line has been moved part way around the circle (in a counterclockwise direction) to (thetaF) = 130°.

Given this information, what is the angular speed of the disk after it has traveled one complete revolution (when it returns to its original position at -90°)?

1- Why is fermentation important for yeast?

2- Which process DOESN'T completely break down carbs? Fermentation or respiration? How does this affect the amount of ATP released?

3- Why would a patient die from having distilled water administered intravenously (it goes directly into the bloodstream)?

4- How does the process of preserving meat (how it can be stored for months w/o refrigeration) by covering it with salt & spices work?
--------------------------------
1- I have no idea & I can't find it anywhere.

2-- I think its fermentation, and I think that as a result less ATP will be released..but idk if that makes sense.

3- I know it has something to do with the red blood cells, I think that they burst because of the hypotonic environment..

4- I think it has to do with the hypertonic environment created by the salt & spices..but I don't understand the details or anything beyond that in regard to the preventing the meat from spoiling.

Please Help me! Thank You!
