A very thin insulating annulus (a disk with a hole) has an outer radius R, and an inner radius of R/2. There is a charge Quniformly distributed over the surface of the annulus. The z-axis of the annulus would be perpendicular to the surface of this paper, located at the center of the disk. Consider the center of the disk to be the origin. A.Find the potential as a function of distance zfrom the annulus, along the axis.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

no image, but probably absorption

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
