Water has a pressure of 3.00 x 105 pa and a speed of 1.00 m/s as it flows through a horizontal pipe. at a certain point, the pipe narrows to one-fourth its original diameter. (remember the radius is half of the diameter, so its radius will also be one-fourth its original size.) what is the speed of the water flow in the narrow section of the pipe? . a.. 16.0 m/s. c.. 16.2 m/s. b.. 12.6 m/s. d.. 22.6 m/s

Which composition of water moves to begin a deepwater current?

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
