Light travels through space at a speed of 3.0 × 108 m/s. A space probe is traveling at 2.5 × 108 m/s when one of its spotlights is turned on. What speed would an observer on Earth measure for the light from the spotlight? A.
3.0 × 108 m/s

B.
5.5 × 108 m/s

C.
0.5 × 108 m/s

D.
The speed would depend on whether the probe is moving toward or away from Earth.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
