The earth receives 1.8 1014 kJ/s of solar energy. What mass of solar material is converted to energy over a 24 h period to provide the daily amount of solar energy to the earth?

I believe you have to use E = MC^2 but am not sure how to get the units right (i need answer in kg)

I'm having problem with some basic 2nd order equations. The problem states, find the solution of the given initial value problem: 4y'' - y = 0; y(-2) = 1 and y'(-2) = -1. The ANSWER is y = -1/2e^((t+2)/2) + 3/2e^-((t+2)/2) Thanks for the help.

In energy terms, ionization of an electron in an atom corresponds to the transition from whatever quantum state the electron is in to an energy of 0 kj/mol. calculate the energy in joules needed to remove one electron in the n=1 state from a hydrogen atom.

N=1 is -1312.04 kj/mol, but i have no idea what the question is asking me? help!!
