At a particular temperature the speed of sound is 330 m/s and its frequency is 990 hz. choose the correct period of the wave in fractional form.

The correct answer of the question is : 0.001 s.

CALCULATION:

As per the question, the speed of sound v = 330 m/s

The frequency of the sound f = 990 Hz.

Let the wavelength of the wave is .

The wavelength of the wave is calculated as-

                       wavelength

                                               =

                                               = 0.33 m.

Now we are asked to calculate the time period.

The time period of the wave is reciprocal of frequency.

Mathematically time period T =

                                                 =

                                                 = 0.001 s.

As per the question, we need the period.

Hence, the period of the wave is 0.001 s.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
