A kid has an ideal slingshot as in the figure below. If the kid pulls straight back on the slingshot with a force F = 10 N as shown, what is the magnitude of the tension in one of the bands? Assume α = 55 ∘.

Energy is the ability to do work which measures what

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.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic
