Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface.
what would have to be the mass of this asteroid for the day to become 22.0% longer than it presently is as a result of the collision? assume that the asteroid is very small compared to the earth and that the earth is uniform throughout.

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

107.1 mhz has higher energy photons. the photon energy increases directly proportional to frequency. however if the station operating on 90.5 mhz transmitter's power is 1.184 times or higher than that of the station operating on 107.1 mhz transmitter's power, then the 90.5 mhz signal will have higher energy because the additional photons makeup the difference. the total energy in electromagnetic radiation is the product of the energy per photon and the number of photons (i.e. amplitude of the wave) in the radiation.
