ASTRONOMY FINAL- HOLTZ TXST with 100% correct solutions 2024

Suppose you drop a feather and a bowling ball from the same height at the same time in a chamber where there is no air. What will happen? correct answers they will hit the ground at the same time why does the moon always show the same face toward Earth? correct answers The moon has slowed its rotation rate until one face of the moon is tidally locked to the Earth Electronic transition between energy levels in an atom cause photons of discrete energies to be emitted or absorbed from the atom. By analyzing the resulting spectrum: correct answers we can identify or "fingerprint" the atom thus determine what element the atom is The force of gravity is an inverse square law. This means that if you double the distance between two large masses the gravitational force between them correct answers is now only one forth between them how does the space shuttle take off? correct answers Hot gas shoots out from the rocket and, by conservation of momentum, the shuttle moves in the opposite direction. we know that an objects momentum will not change if the object is left alone- but a force will change the objects momentum. However an equal and opposite force changes some other objects momentum by an equal and opposite amount. the result of this is correct answers total momentum is conserved A planet is most likely to have tectonic activity if correct answers it is relatively large in size and has high internal temperature which of the following is not a pattern of motion in our solar system correct answers planets all rotate in the same direction Radar imaging and spectroscopy from orbiters of venus show all the following except correct answers erosion caused by weather and ice which of the following does not provide evidence that mars once had large amounts of flowing water correct answers the presence of canals of mars as reported by percival lowell and the face on mars what are greenhouse gases correct answers gases that absorb infrared light
