log(subscript 2)(0.5) I know how to convert it into: 0.5 = 2^(y) but then how do I find y?

Chemistry
Explain exactly how you would make 1 liter of a .10 M acetic acid solution using vinegar from the lab as the stock solution to be diluter.

psychology
in my psychology textbook this is called the bystander effect with the answer choices you have i would say diffusion responsibility, but i am not sure. It is definitely not A though.

physics
A block of mass m = 2.00 kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 7.20 kg which is at rest on a horizontal surface Determine the speeds of the two blocks after the collision. lighter block = heavier block = what wou...

physics
After a completely inelastic collision between two objects of equal mass, each having initial speed v, the two move off together with speed v/6. What was the angle between their initial directions? if this is the equation 2mvcos(theta)=2mv/6 what numbers would replace m and v?
