Apositively charged non-metal ball a is placed near metal ball b. prove that if the charge on b is positive but of small magnitude, the balls will be attracted to each other.

a. the positive charges on the sphere b move to the side closer to sphere a, while the negative charges move to the side further away from sphere a. the polarization of charge on a will cause a greater attractive force than the repulsion of the like charges.

b. the negative charges on the sphere a move to the side closer to sphere b, while the positive charges move to the side further away from sphere b. the polarization of charge on a will cause a greater attractive force than the repulsion of the like charges.

c. the positive charges on the sphere b move to the side closer to sphere a, while the negative charges move to the side further away from sphere a. the polarization of charge on b will cause a greater attractive force than the repulsion of the like charges.

d. the negative charges on the sphere b move to the side closer to sphere a, while the positive charges move to the side further away from sphere a. the polarization of charge on b will cause a greater attractive force than the repulsion of the like charges.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
