PLEASE HELP An electron moves from n=2 to n=3. Use the Balmer series to find the following; i)wavelength for n=2 ii)Energy for n=2 iii) Wavelength for n=3 iv) Energy for n=3 v) Energy absorbed when moving from n=2 to n=3. (h=6.63*10^-34Js; c=3*10^8m/s) (Hint: ∆E=Ef - Ei where f=final and i=initial)

Which term best describes the phrase “something that happens”?

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
