Science
A large water body can affect the amount of snowfall a region receives in the winter because of the high winds and moisture.

Chemistry
I kept on getting 1.13s^-1 as my value for k2 but it's wrong...

Chemistry
Given that the initial rate constant is 0.0190s^-1 at an initial temperature of 20 degrees Celsius, what would the rate constant be at a temperature of 170 degrees Celsius? Activation energy = 45.2kJ/mol

Chemistry
The rate constant for a certain reaction is k=8.90×10^−3 s^-1. If the initial reactant concentration was 0.400M, what will the concentration be after 13.0 minutes?

Chemistry
If 50.00mL of 1.10M NaOH is added to 25.00mL of 1.86M HCl, with both solutions originally at 24.70 degrees Celsius, what will be the final solution temperature? (Assume that no heat is lost to the surrounding air and that the solution produced in the neutralization reaction ...

Physics
You have to look the equation of the solid cylinder I=1/2(m*r^2) and change the units of w to rad/s. After that, you can calculate and get the answer.
