Two speakers are placed side by side and are described as having constructive interference. how do you know when constructive interference of sound waves has occurred? question 4 options: the sound waves will combine to be larger, so the volume will be louder. the waves will flatten out or disappear completely when two waves meet each other. the sound waves will combine, so the waves will cancel each other out. the sound waves will combine to be larger, so there will be no volume.

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s

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.

What property of an object determines its inertia?
