Suppose you drop a rock at rest into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. neglecting the time required for sound to travel up the well, calculate the distance to the water if the sound returns in 2.4700 s. then calculate the distance taking into account the time for sound to travel up the well. the speed of sound in this case is 340.00 m/s as well.

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
