Assume that a 10-km asteroid hits the earth at about 20 km/s Computer simulations suggest that for large-energy impacts similar to the one described, water having about 3 times the mass of the asteroid is essentially instantly vaporized in an ocean impact. What fraction of the asteroid’s energy does the energy required to do this represent? About ___% of the asteroid’s energy is required to instantly vaporize water 3 times the mass of the asteroid.

Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.

The European Space Agency launched a probe called Rosetta in March 2004. In August 2014, Rosetta reached its destination: a comet called 67P/Churyumov-Gerasimenko. Rosetta is the first spacecraft to rendezvous with a comet, and plans to orbit the comet. It contained a lander craft, called Philae. The Philae lander has several scientific instruments onboard, used to study the comet. ALICE is an ultraviolet imaging spectrograph, used to search for noble gases in the comet core. The ALICE instrument uses potassium bromide as one of the compounds in the analysis of noble gases. Potassium bromide has a specific gravity of 2.74. Assume the lander has a liquid sample of potassium bromide onboard that fills a 1.49-gallon [gal] container. What is the mass of the potassium bromide sample in the container, in units of kilograms [kg]?
