A certain copper wire has a resistance of 12. 0 ω. At some point along its length the wire was cut so that the resistance of one piece is 5. 0 times the resistance of the other.

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

Phase changes are chemical changes. true or false

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
