Given the equation of orbital velocity and the period equation, briefly explain how to use lunar observations to deduce the mass of the Earth. Show your work. Given two spectra, be able to identify which has a higher or lower temperature. A greenhouse gas is defined as a gas that blocks infrared radiation. Use the laws of continuous radiation to explain why greenhouse gases result in a net warming of the Earth.
Greenhouse gases block both incoming and outgoing radiation.
Based on Monday's film about the Greenhouse Effect, describe two methods scientists use to determine the global average temperature prior to recorded history. Explain your answer. Given a simple energy level diagram for an atom, be able to state what energies of light can be emitted or absorbed. Explain with the help of a simple diagram. Given the formula for resolution, be able to explain why large aperture telescopes have better resolution and why radio telescopes, despite their gigantic apertures, have poor resolution compared to optical telescopes.
