A solar powered medical refrigerator for vaccine storage and transport uses a 12V battery as the power source. Battery capacity is given in terms of A-hr, e. g., a 20 A-hr, 12 V battery can supply 20 A of current for 1 hour at 12 volts. Once the fridge is cooled down, it requires 420 W-hrs (i. e., requires 420 W of power for 1 hr) of energy to maintain its temperature over a 24 hour period. What is the minimum battery size that would be needed to power the refrigerator for two days if there is no sun

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
