If it were possible to remove gravity and friction, think about what would happen to a football if it were tossed into the air. which statement best describes the force(s) acting on the football?

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.

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
