In july 2005, nasa’s "deep impact" mission crashed a 372-kg probe directly onto the surface of the comet tempel 1, hitting the surface at 37,000 km/h. the original speed of the comet at that time was about 40,000 km/h, and its mass was estimated to be in the range (0.10−2.5)×1014kg. use the smallest value of the estimated mass.
(a) what change in the comet’s velocity did this collision produce? would this change be noticeable?
(b) suppose this comet were to hit the earth and fuse with it. by how much would it change our planet’s velocity? would this change be noticeable? (the mass of the earth is 5.97×1024kg.)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
