There has long been an interest in using the vast quantities of thermal energy in the oceans to run heat engines. A heat engine

needs a temperature difference, a hot side and a cold side. Conveniently, the ocean surface waters are warmer than the deep ocean waters. Suppose you build a floating power plant in the tropics where the surface water temperature is ≈≈ 30 ∘C∘C. This would be the hot reservoir of the engine. For the cold reservoir, water would be pumped up from the ocean bottom where it is always ≈≈ 5 ∘C∘C.What is the maximum possible efficiency of such a power plant? In%.

Answer:

\eta_{th} = 8.247\%

Explanation:

The maximum possible efficiency for the floating power plant is given by the Carnot's Efficiency:

\eta_{th} = \left(1-\frac{278.15\,K}{303.15\,K}  \right)\times 100\%

\eta_{th} = 8.247\%

When working with a powered instrument, the swirling effect produced by the water stream within the confined space of a periodon
Lina20 [59]

Answer:

Acoustic microstreaming

Explanation:

Acoustic microstreaming is the swirling effect produced by water stream confined in a spaced of a periodontal pocket.

  • It is the movement of water in a particular direction as a result of mechanical pressure within the fluid body.
  • They are often used in dental procedures to remove particulates from the teeth.
  • It mostly relies on the properties of sound waves to achieve this goal

What happens when a particle and its corresponding particle of antimatter meet?
Nataly [62]
The combined mass of the two particles is completely transformed into energy (photons). The particle and the antiparticle are annihilated, turning all their mass into energy. Mass in physics is a property of a physical body. When a net force has applied a measure of an object's resistance to acceleration. It is also a large body of coherent matter with no definite shape. It is also the numerical measure of its inertia or the fundamental measure of the amount of matter in the specific object. Energy in physics in the ability of people to do work. There are many forms of work such as light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on.
