For a substance to change from a solid to a liquid, what must happen to its
particles?
A. They must gain enough kinetic energy to break out of their rigid
structure and move independently.
B. They must lose enough of their kinetic energy that their motion is
influenced by the attractions between them.
C. They must lose enough of their kinetic energy so that the
attractions between them hold in place as they vibrate.
O D. They must gain enough kinetic energy to allow them to move
freely while still being attracted to one another.

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].

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
