Answer:

Low level jet

Explanation:

Jet streams can also form close to the earth's surface. of all such type of jet one jet  grows just over the main central plains of  United States, where speeds approaching 60 knots are rarely reached. This high point wind speed jet is recognised as low level jet, which typically comes from south or southwest.

As title indicates, , it termed as a rapidly-moving stream of air in low atmosphere levels .

The Doppler effect is the apparent change in frequency due to the movement of the source and the observer. This means an object
Alekssandra [29.7K]

Answer:

Doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the observer(detector).

Explanation:

Doppler effect in light is actually a relativistic effect but somewhat similar to the one which happens in sound waves.

When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector, as a result the frequency decreases(we know that frequency of light= speed of light/wavelength of light. Here speed of light is constant and frequency of light is inversely proportional to its wavelength)

Due to this decrease in frequency the light emitted from the source appears more red, since red color is on low frequency side in the electromagnetic spectrum.

Similarly for the source moving towards the detector, the wavelength appears to be decreased, thereby resulting in increase in frequency and the source appears blue. The shift in frequency is known as doppler shift.

The shift in frequency when the source is moving away is known as redshift and the one where the source is moving towards detector is known as blueshift

Upon examining layer M, you find that it contains a small proportion of the radioactive isotope - Potassium-40, which decays int
Westkost [7]

Answer:

t = 2.6 billion years

Explanation:

If potassium becomes 25% of its initial value

so we can say it becomes half two times

as we know that 25% means it is 1/4 times of initial value

so we will have

N = N_o e^{-\lambda t}

here we know that

N = 0.25 N_o

0.25 = e^{-\lmabda t}

ln 4 = (\frac{ln 2}{T_{1/2}}) t

t = 2 T_{1/2}

t = 2(1.3 billion \: years)

t = 2.6 billion years
