There is a straight-forward explanation if we break down the process of "calculating the force": - In order to calculate the force acting on the Northern Hemisphere (NH), we can break the NH down into tiny fractions and calculate the "forces that act on each of those fractions", including: -->...

Oh... I understand... sorry for the inconvenience :(

Firstly, I think we can solve the ionization potential of He1+ at ground state (1) easily with the Bohr model, as the atom now have 1 nucleus (with 2 protons) and 1 electron, similar to the Hydro atom with a larger nucleus. In the sun, I understand that ionized gas (He1+) located in an electric...

I think it makes sense to "state their relative importance" by comparing 2 factors amongst sources: radiation doses and the source's radiation's effects. For the doses comparison, you can visit the "National Council on Radiation Protection & Measurements (NCRP), Report No. 160", while for the...

It is hard to compare the energy between those rays in general as each radiation's range of energy can overlap each others. Yet, each type of radiation appears more frequently in nature in specific ranges of energy - "typical" energy - and comparing between those values can give us some...

Currently a high school student, I struggled a lot with complicated concepts and phenomena in physics. Yet, I have an inexplicable urge to explore and understand physics - probably because I love physics' elegant view of the world around us - therefore I spent time roaming through books and...
