the maximum range of a projectile is 2÷√3 times its actual range what is the angle of the projection for the actual range

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.

What is a costume plot? why is it important to a film or theater production?

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
