An object has a net charge of +5 Coulombs. A. It has too few electrons because the charge is an odd, prime number

B. It has too few electrons because the net charge is positive

C. It has too many electrons because there is no exponent associated with it

D. It has too many electrons because the net charge is positive

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

Anybody wanna ? (picture included? )
