A block with mass 0.64 kg is forced against a horizontal spring of negligible mass, compressing the spring a distance of 0.38 m (see figure). The coefficient of kinetic friction between the block and table is 0.410. The Spring constant is k= 100 N/m a, What is the elastic potential energy stored initially in the spring. b,How far will block slide along the table before coming to rest?

A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After i is released the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment with a box of mass 2m A) the lighter box will go twice as high up the incline as the heavier box. B) both boxes will have the same...
Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference...
Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference ?V between the plates of a capacitor. Capacitance is determined only by the physical properties of the capacitor. The stored charge ?q and the potential difference ?V are independent of the size and shape of the capacitor. The net charge on a capacitor is zero, and therefore the potential difference ?V cancels. The stored charge ?q is inversely proportional to the potential difference ?....
