Question 18 of 25 The diagram below shows the velocity vectors for two cars that are moving
relative to each other.
25 m/s west
Car 1
20 m/s west
Car 2
From the frame of reference of car 2, what is the velocity of car 1?
A. 5 m/s west
B. 5 m/s east
C. 45 m/s east
D. 20 m/s west

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?
