The magnitudes of two vectors Va and Vb are 5 and 7, respectively, and the magnitude of their sum Vs is 10 (i.e., |Va| = 5, |Vb| = 7, |Vs | = 10). The angles ? and ? in the figure below are:
(A) ? = 40.5°, ? = 27.7°
(B) ? = 27.5°, ? = 40.7°
(C) ? = 48.5°, ? = 37.7°
(D) ? = 14.5°, ? = 17.3°
(A) ? = 40.5°, ? = 27.7°
(B) ? = 27.5°, ? = 40.7°
(C) ? = 48.5°, ? = 37.7°
(D) ? = 14.5°, ? = 17.3°

a. True b. False Indicate whether the statement is true or false
Substance A has twice the specific “heat” as substance B. Suppose we put 100-g blocks of these substances in direct sunlight. Assume both blocks are black and present the same surface area to the incoming sunlight. After a certain period of time, how are the temperature changes ?TA and ?TB of these blocks related (assuming they lose little heat to their surroundings)?
A. ?TA ? 2?TB B. ?TA ? ?TB, as both receive the same amount of energy C. ?TB ? 2 ?TA D. ?TA = ?TB = 0, because neither receives any heat
What is the difference between weather and climate?
A) Weather refers to atmospheric conditions in the troposphere, while climate refers to atmospheric conditions in the stratosphere. B) Weather is something that we can control, and climate is not. C) Weather refers to small storms and climate refers to large storms. D) Weather refers to short-term changes in wind, rain, and temperature, while climate refers to the long-term average of weather.
