Fusion of hydrogen into helium is the primary method of energy production in stars. depending on the mass of the star, this can happen in one of two different ways: the proton- proton chain (low-mass stars like the sun) or the cno cycle (high-mass stars) a. what is the temperature needed for each of these two processes to occur? b. how much energy is released through each process?

How much work would be needed to raise the payload from the surface of the moon (i.e., x = r) to an altitude of 5r miles above the surface of the moon (i.e., x = 6r)?

Which statement best explains why an object weight less on mercury than it does on earth

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate
