How does gravitational lensing tell us about the mass of a galaxy cluster?
A) The lensing broadens spectral lines, and we can use the broadening to "weigh" the cluster. B) Using Einstein's general theory of relativity, we can calculate the cluster's mass from the precise way in which it distorts the light of galaxies behind it. C) The lensing allows us to determine the orbital speeds of galaxies in the cluster, so that we can determine the mass of the cluster from the orbital velocity law. D) Newton's universal law of gravitation predicts how mass can distort light, so we can apply Newton's law to determine the mass of the cluster.
Two displacement vectors have magnitudes of 5.0 m and 7.0 m, respectively. If these two vectors are added together, the magnitude of the sum
A) is equal to 2.0 m. B) could be as small as 2.0 m or as large as 12 m. C) is equal to 12 m. D) is equal to 8.6 m.
All electromagnetic waves have the same physical characteristics. They differ only in frequency and wavelength. How are they classified into different types?
For a body emitting blackbody radiation, the total power emitted is proportional to the 4th power of the body's absolute temperature: (T in kelvins) and the wavelength of the emitted EM radiation that has the highest intensity is inversely proportional to the body's absolute temperature according to: ( in meters, T in kelvins) Assume an object is emitting blackbody radiation. A body in a room at
300 K is heated to 3,000 K. The wavelength of the most intense EM radiation emitted by the body at 3,000 K is the wavelength of the most intense EM radiation at 300 K. a. 0.0001 times b. 0.1 times c. the same as d. 10 times e. 10,000 times
