If a wave has a frequency of 4 hz and a speed of 24 m/s, which is its wavelength?

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.

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

What is the measurement of how fast an object moves relative to a reference point?
