If "yes", then determine the velocity of k' relative to k. if "no", then determine the velocity of the frame in which the two events are simultaneous. express the velocity vector using the variables a and c and the unit vectors, i, j, and k; for example, 2i + 2j is a vector which bisects the x and y axes.

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
