The demonstration in this figure is often shown as a magician's trick. What in fact is the "trick?"
a. When the magician yanks the tablecloth rapidly, the inertia of the dishes prevents them from accelerating significantly during the short time the force of friction from the moving tablecloth acts.
b. The magician uses magnets or some other external device to keep the dishware in place.
c. The tablecloth has almost zero mass, or inertia. Hence, it is easy to pull away from the dishware.
d. The mass of the tablecloth prevents it from accelerating rapidly enough to exert much force on the dishes.
e. The dishes have much less inertia than the tablecloth.
