Which object would have a greater buoyant force: 350 g of copper (ρ= 8,890 kg/m3) or 350 g of ice (ρ= 917 kg/m3) if both are submerged in water?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

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.
