We believe that all of the terrestrial planets had similar histories when it comes to impacts from space. explain how this idea can be used to date the formation of the martian highlands, the martian basins, and the tharsis volcanoes. how certain are the ages derived for these features (in other words, how do we check the ages we derive from this method)?

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
