2 blocks of masses 1.0 kg and 2.0 kg are pushed by a constant applied force F across a horizontal frictionless table with a constant acc such that the blocks remain in contact w each other. the 1.0 kg block pushes the 2.0 kg block with a force of 2.0 N. acceleration of the two blocks?

When a book falls from a shelf to the ground without anyone pushing on it, no work is done on the book. true or false

Explain the consequences of this addiction to the brain tissue

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.
