Geothermal energy can heat, cool, and generate electricity: Geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use applications.

Tidal can be harnessed in three different ways; tidal streams, barrages, and lagoons.

If a woman needs an amplification of 1.0 ✕ 105 times the threshold intensity to enable her to hear at all frequencies, what is h

Damm [24]

Answer:

50 dB.

Explanation:

given,

Amplification needed by the woman,I= 1 x 10⁵ I₀

where as I₀ is the threshold frequency

overall hearing loss of the woman= ?

Using the equation of sound intensity level

$\beta(dB) = 10 log(\dfrac{I}{I_0})$

$\beta(dB) = 10 log(\dfrac{1\times 10^5\ I_0}{I_0})$

$\beta(dB) = 10 log(1\times 10^5)$

$\beta(dB) = 50\ dB$

The overall hearing loss of woman is equal to 50 dB.

In a 4.0-kilometer race, a runner completes the first kilometer in 5.9 minutes, the second kilometer in 6.2 minutes, the third k

Svetlanka [38]

As per the question the total distance is given as 4 km.

We are asked to calculate the average speed.

The time taken by the body to travel each kilometre are 5.9 min,6.2 min.,6.3min. and 6 min. respectively.

The average speed of a body is defined as the ratio of total distance travelled by the body to the total time.

Mathematically the average speed is written as _

V= Total distance/Total time

i.e V = S/T

Where S is the total distance travelled and T is the total time

Here total distance (S)= 4 km

The total time T= (5.9+6.2 +6.3+ 6.0 )minutes

=24.4 min.

Hence average speed V = 4 km/24.4 min

= 0.16 km/min.

Hence the correct option is A .

DVDs and Blu-ray disks store information in patterns that are read by laser light. The shorter the wavelength of the light, the

Tju [1.3M]

Answer: The Bluray Disk can store more information

The wavelenght of red light is around 700nm, whereas the wavelenght of violet light is around 400nm. Since the violet light has smaller wavelenght the data tracks on a Blu-ray Disk can be spaced closer together and the Blueray Disk can store more information

Explanation: Because a disk work by storing data using bits, the more bits can be stored in one place improves the total storage on the unit. The less the space to storage the bit, the more space overall for the disk.

What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer? What is the quality of the so

Damm [24]

Answer:

A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch

B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.

Explanation:

From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.

Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.

Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.
