Multiply out then simplify:

a- 3+2(x-1)
b- 5-2(x+3)
c- 1+2(x-1)
d- 6-3(w-2)

could you show working aswell because it would help me in the future with these kind of questions.

Over this last summer, I spent a lot of time on a nearby lake. I heard of water tornadoes but wasn't sure of the risk of being attacked by one. Where do they come from and what can I do to protect myself?
Also, I have a science project coming up soon and since this is such a strong interest of mine, I would like to recreate one. Any ideas on how to recreate a water tornado?

Cylindrical pulley w/ the following:
mass, M = 6.9 kg
radius, r = 0.811 m
moment of inertia 1/2 Mr^2

is used to lower a bucket (m=2.9 kg) into a well. The bucket starts from rest and falls for 3.3 s, acceleration of graviy is 9.8 m/s^2.

A) What is the linear acceleration of the falling bucket in units of m/s^2?

B) How far does it drop in units of m?

C) What is the angular acceleration of the cylinder in units of rad/s^2?

I know that proteins are joined together by dehydration synthesis between the acid group of one molecule and the amine group of another; the bond that is formed is called a peptide bond.
And I know that hydrolysis is the decomposition reaction that uses water to break down a larger molecule into smaller ones.

BUT -- Hydrolysis of a protein would result in what?
