Explain the underlying biomechanical constructs of spring, change of direction, and agility performance.

How can the Pressure-Volume Work be calculated?

With respect to orderly and disorderly states, what do natural systems tend to do? Can a disorderly state ever transform to an orderly state? Explain.

4. to convert the kinetic energy of water into the mechanical shaft energy. Water enters the turbine, at the inlet, with the velocity V, = 40m/s and the mass flow rate m = 1,000kg/s. Water exits the Vi,-40ms Figure on the right shows a hydraulic turbine designed turbine with a negligible velocity, say, Vout = 0 m/s.The efficiency of HzO the turbine is 75 %. Potential energy and flow work can be ignored. 4а. Please calculate the specific kinetic energy of water entering the turbine ( ɛ or ke; in J/kg). 4b. Please calculate the rate of total kinetic energy of the water flow (E, or KE; in J/s or W) 4с. Please determine the mechanical power output of this turbine (W, out > in W or kW). 4d. Please determine how much mechanical energy would this turbine generate during an hour

Without changing the mass or height what else do you think you could do to design a system in which GPE and KE values are more equal ?

Can you relate the idea of scaling to the governance of small versus large groups of citizens? Explain.

hw need help ，please step by step in detail explain

What is the Internal kinetic energy?

Using the principles of unit analysis, express the terms motion energy, pressure, kinetic energy losses, and pump power in terms of water column height.
