DITIONAL PRACTICE 1. Earthquakes also produce transverse waves that move more slowly than
the p-waves. These waves are called secondary waves, or s-waves. If the
wavelength of an s-wave is 2.3 X 10^ m, and its frequency is 0.065 Hz,
what is its speed?

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].

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?

By what primary heat transfer mechanism does the sun warm the earth?
