How much time would it take for the sound of thunder to trace 1,500 meters if sound travels at a speed of 330m/sec

Apossible explanation for a set of facts that can be tested by further investigation is called

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

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.
