A ball of mass 1000g is dropped from a height of 5m and rebounded to a height of 25m calculate the kinetic energy just before impact initial velocity and kinetic energy

Oxygen and nutrients are moved through the body by the: a. circulatory system c. lymphatic system b. digestive system d. reproductive system

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.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
