Suppose a cylindrical habitat in space 6.80 km in diameter and 24 km long has been proposed. such a habitat would have cities, land, and lakes on the inside surface and air and clouds in the center. this would all be held in place by rotation of the cylinder about its long axis. how fast would the cylinder have to rotate to imitate the earth's gravitational field at the walls of the cylinder? answer in rad/s.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r Γ f) Β· n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, β5, 4] n, r = [β3, 5, 2] m, and n = [6, 5, β7].

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.05 kilograms and a mean that can be set by the operator. at what level should the mean weight be set if it required that only 1% of the bags weigh less than 9.5 kilograms? round the answer to 2 decimal places.
