If you step outside when the temperature is well below freezing, you can bet it will not be raining. You are more likely to see snow if there is any precipitation at all. Water in the clouds is so cold that it turns into ice crystals. What are some of the physical differences between rain water and ice crystals such as snow?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · 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, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
