An fcc metal has a lattice spacing of a-3.060 angstroms. calculate the volume (in angstroms) of the interstices (empty space) in the unit cell. volume of the interstices-volume of the unit cell (1-atomic packing factor) where the atomic packing factor for fcc metals is 0.74 änd the volume of a unit cell with the side a will be a 8.9966

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.
