The Moon receives all of its energy in the form of radiation from the Sun. By what process or processes does it lose heat? How do you know?
Homework Answers
The moon also looses heat energy as it gained from the sun. Since we know that from all three mode of heat transfer( conduction, convection, and radiation) radiation doesn't require medium to transfer heat. Since on moon surrounding is nearly vacuum so the moon loss heat by radiation.

The Earth receives energy from the Sun at the rate of 1.4 kW/m . A sister planet orbits a star at the same distance as the Earth’s distance from the Sun. If the sister planet’s star has a temperature 2.1 times that of the Sun’s temperature, what is the rate that the sister planet receives energy from its sun？

Answer all three parts
The sun transfers energy to the earth by radiation at a rate of
approximately 1.00 kW per square meter of surface. Part A If this
energy could be collected and converted to electrical energy with
26 % efficiency how large an area (in square kilometers) would be
required to collect the electrical energy used by the United
States? (1.0×1019 joules per year).

Warm Up The surface of the Earth receives approximately 1000 W/m2 (Watts per square meter) of energy from the Sun. This number rises to about 1386 W/m2 in the upper atmosphere (r 6.4 x 106 m) The sun is 1 AU (1.496 x 1011 m) away Over what area is the Sun's energy spread at the Earth's distance? How much power is the Sun releasing?

se 4: Phases of the Moon Everyone has seen the Moon, which is a natural satellite that orbits the Earth. As the Moon rotates around the Earth it is exposed to various amounts of light from the Sun. The reason for this is simple, the Moon at night because it is reflecting light produced by the Sun and because the Earth is slightly out of the direct line of sight between the Moon and Sun. If it were not, a...

In its core the Sun changed, hydrogen into helium and produces energy by this nuclear fusion process. Each hydrogen atom has a positively charged center (a proton) and a negatively charged electron that exists around the periphery of the atom. The heat of the Sun pulls the electrons off the hydrogen atoms, leaving positively charged protons behind. To make energy the sun has to force these positively charged particles very close together so that a very strong but short range...
