Most of the oceans salts come from the gradual processes of weathering, erosion, and deposition

Answer:
v2 = 12m/s
Explanation:
To find the velocity of water in the lower tube you use the following formula:
(1)
v1: velocity in the first tube
v2: velocity in the second tube
A1: area of the first tube
A2: area of the second tube
From the expression (1) you can obtain the velocity v2, that is the velocity of water in the second tube:
you replace the values of the parameter in order to calculate v2:
hence, the velocity of the water is 12m/s
Well, It rather depends on your definition of "machine." The normal physics set of simple machines - levers, pulleys, ramps all give you increased the force at the expense of reduced speed or increased the rate at the cost of reduced force. So, no - by definition a machine is an arrangement for multiplying one while paying the cost by reducing the other. You are looking at an example of the Conservation of Energy. One of the giant rules we are pretty sure cannot be violated.<span>

Explanation:
Classical Thermodynamics studies the relationships between the State functions of the system: i.e. Pressure, Temperature, Volume, Energy, Entropy etc. In classical thermodynamics we pretend that we don’t know anything about the microscopic constituents (atoms) of our thermodynamic system. We do not talk about concepts like microstates, or ensemble averages, since such concepts require a more fine-grained perspective of the universe.
Statistical Thermodynamics explores how particular microscopic elements of the structures can be statistically related to the functions of the state. Depending on the limit in which we are, these microscopic elements can be either classically or mechanically quantified. In the end, nearly all statistical thermodynamics are derived by summing up the microscopic properties to derive equations for the functions of the macroscopic state.
