A small metal sphere with a charge of +2.10 x 10-6 C is to the left of another sphere with a charge of 0.057 C. They
experience a force of 44.3 N. Calculate the distance
between them.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

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.

Acertain radio station broadcasts radio waves that have a wavelength of 298cm what is its broadcast frequency?
