Weight and g: An astronaut drops a marble on the surface of the airless Planet Z-49 and observes that it takes 1.02 s for the marble to fall 2.00 m starting from rest. She also knows that the radius of Z-49 is 3.39 × 106 m. From this information, what will she determine for the mass of Z-49? (G = 6.67 × 10-11 N ? m2/kg2)
A. 3.30 × 1023 kg. B. 6.62 × 1023 kg. C. 4.62 × 1023 kg. D. 8.09 × 1023 kg. E. 9.95 × 1023 kg.
What observational evidence supports the hypothesis that elliptical galaxies are born from relatively dense protogalactic clouds?
A) Elliptical galaxies have stars packed more densely together than spiral galaxies. B) Elliptical galaxies are generally larger than spiral galaxies. C) Even very distant elliptical galaxies tend to lack young, blue stars, indicating their stars formed early and rapidly. D) Elliptical galaxies have more and denser gas than spiral galaxies. E) The stars in elliptical galaxies are denser than those in spiral galaxies.
Just as water flows from a region of high pressure to a region of low pressure, electric charge flows from a region of

What determines how much light bends when it enters a transparent material?
a. The angle of incidence of the light alone determines the bending. b. The index of refraction alone determines the bending. c. The type of material alone determines the bending. d. The index of refraction and the angle of incidence determine the bending. e. The state of matter of the material determines the bending.
