You see a coin at the bottom of a pool. The light reflects from the coin to the surface forming an angle of Θ1 = 10° with the normal. If water has an index of refraction of 1.33, determine Θ2. [Round to the nearest tenth.]

A) 13.3°
B) 14.9°
C) 22.5°
D) 28.7°

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)

Thermal radiation gets its name because
