Show that in general a skew-symmetric tensor such as the spin tensor W has only one real principal value λ. Determine λ and the corresponding direction ˆn in terms of the components w1 = −W23, w2 = −W31, w3 = −W12 of the vector ˆω.

Write a question about how changing temperature affects the gas inside the sports ball

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.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
