A solar sail is made of aluminized Mylar having an emissivity of 0.03 and reflecting 91% of the light that falls on it. Suppose a sail with area 1.26 km2 is oriented so that sunlight falls perpendicular to its surface with an intensity of 1.40 103 W/m2. To what temperature will it warm before it emits as much energy (from both sides) by radiation as it absorbs on the sunny side

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

none, its a machine
