Aphysics major is cooking breakfast when he notices that the frictional force between his steel spatula and his teflon frying pan is only 0.200 n. knowing the coefficient of kinetic friction between the two materials, he quickly calculates the normal force. what is it?

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

What are the applications of electromagnetic waves

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.
