f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...

Newton's law of universal gravitation strictly applies to perfectly spherical bodies. Many celestial bodies, like the Sun and Earth, are not perfect spheres. This has a measureable effect on the trajectories of orbiting satellites. Restricting attention to equatorial orbits, the gravity law can be corrected in a simple way to account for the Sun's imperfect shape. →Fg=−GMmr2(1+3J2R22r2)^rF→g=−GMmr2(1+3J2R22r2)r^ where G=6.67×10−11 N⋅m2/kg2G=6.67×10−11 N⋅m2/kg2 is the universal gravitation constant, M=1990000 kgM=1990000 kg is the mass of the Sun, mm is the mass of...
