Average amount of time wind machines operate
Rasek [7]

The wind machine on an average operates for a time of about \boxed{3-4\text{ hours}}.

Explanation:

The wind energy is the method of using the energy carried by the wind to generate the power. The wind energy is the considered as the conventional  and clean source of energy.

The wind machines require the high power winds to rotate the blades of the windmill and produce power using the energy of the moving wind.

The winds blow at such high speed for a very small time during the day, the wind machine cannot be expected to work for a longer time during the whole day.

The wind energy can be obtained form a wind mill for a limited time unlike the other form of energy like thermal energy or even the solar energy. The thermal energy can be obtained at anytime due to burning of fuel whereas the solar energy can at least be obtained during the whole day time.

Thus, the wind machine on an average operates for a time of about \boxed{3-4\text{ hours}}.

Absolute zero (K=0 or -273.15°C) is what temperature on the Farenheit scale? a) 459.4°F b) -301.43 °F c) 233.05°F d) -40.15°F e
ANEK [815]

Answer:

e) None of these is true

Explanation:

Given that

Temperature = 0 K

We know that relationship between kelvin and Farenheit scale

\dfrac{K-273}{100}=\dfrac{F-32}{180}

Now by putting the values

\dfrac{K-273}{100}=\dfrac{F-32}{180}

\dfrac{0-273}{100}=\dfrac{F-32}{180}

So F= - 459.67°F

So we can say that 0 K is equal to  - 459.67°F.

So the our option e is correct.

It uses a series of filters to decompose the multiplexed signals into its constituent component signals. a. Demodulator b. Demul
harkovskaia [24]

Answer:

b) Demultiplexer.

Explanation:

The multiplexed signal occupies the total bandwidth of the communications channel, while that the constituent component signals, occupy only a small part of the bandwidth.

Prior to be demodulated, they must be separated each other, which is done (in a FDM multiplexing scheme) using a series of band-pass filters.
