C. Determine the momentum of one proton as seen by the other proton.
A cube of ice is taken from the freezer at -8.7°C and placed in a 97 g aluminium calorimeter filled with 351 g of water at the room temperature of 20°C. The final situation is observed to be all water at 19°C. What was the mass of an ice cube.
Many people mistakenly believe that the astronauts orbiting the earth are "above gravity." Compute the acceleration because of gravity, g, for space shuttle territory, 245 kilometres above the earth's surface (dashed line in sketch). Earth's mass ..
