How did Kepler himself originally state his second law? - ANSWER-A line joining a planet and the Sun sweeps out equal areas in equal intervals of time How much of the total surface area of the Moon is illuminated by Sunlight during the Full Moon phase? - ANSWER-one half. If Earth had its orbit changed so that at all points along its orbit it was always the same distance from the Sun (circular orbit), how would this affect the seasons on Earth? - ANSWER-They would be the same as they are now If Earth's Moon was Full on May 1,2007. When was it next in the First Quarter phase after this Full Moon? - ANSWER-May 22 If the Earth rotated on its axis more slowly than it does now: - ANSWER-its days would be longer If the Earth were moved to half its current distance from the Sun, how would the force of gravity by the Sun on the Earth change? - ANSWER-It would become four times stronger If the frequency of radiation is twice as large then its wavelength is - ANSWER-half as large If you were to sit on the ground, there would be a force due to gravity pulling you toward the Earth. Which of the following is true according to Newton's 3rd Law? - ANSWER- you are pulling the Earth toward yourself with the same force Most meteors: - ANSWER-are very small (centimeter scale) pieces of rock burning in the Earth's atmosphere. Of the four Galilean moons which is the closest to Jupiter? - ANSWER-Io Saturn is about 10 times as far from the Sun as Earth is (a = 10 AU, roughly). About how many times does Earth orbit the Sun in the time it takes Saturn to orbit just once? - ANSWER-About 30 The densities of the four Terrestrial planets are similar to each other. This means - ANSWER-they are made of similar substances The Earth radius is about 6400 km. If you were in orbit in the Space Station 150 km above ground, the force of gravity you feel from Earth would be: - ANSWER-slightly weaker than when you are standing on Earth

Which of the following does Kepler's Second Law support? - ANSWER-When a planet is closer to the Sun, its speed is greater than when it is farther away Which of the following is FALSE? - ANSWER-The energy of a photon increases in proportion to the wavelength of the radiation Which of the following is not a characteristic of jovian planets? - ANSWER-They have a higher density than terrestrial planets Which of the following is true? - ANSWER-An absorption spectrum appears as a continuous spectrum interrupted by a series of dark lines.
