The perturbation in the ionosphere was created by a powerful transmitter at PGI, which radiated a modulated radio wave continuously upwards. The carrier frequency was fl = 3.5 MHz, the modulation frequency was ~
The resultant amplitude, when two waves of two waves of same frequency but with amplitudes a1 and a2 superimpose at phase difference of π/2 will be :- A a1+a2 B a1−a2 C √a21+a22 D a21+a22 Video Solution Text SolutionVerified by Experts The correct Answer is:C a=√a21+a22+2a1...
Answer and Explanation: The most correct solution to this problem is provided byoption C: wakefulness. Neuroimaging studies have found that high-frequency waves (alpha and...

At what speed should a source of sound move so that stationary observer finds the apparent frequency equal to half of the original frequency View Solution A source is moving towards a stationary observer, so that the apparent frequency increases by 50%. If velocity of sound is 330 m/s, then...
Additionally, high frequency radio transmissions may experience interference from ionospheric effects. Auroras will intensify, growing brighter and with more red colour showing up in the display. They will also push farther south, covering most of Canad...
However, while the stock market isn't zero-sum in the long term, short-term trading and speculation can sometimes resemble zero-sum activities. Day orhigh-frequency tradersmight engage in transactions where one party's gain more closely mirrors another's loss. However, these activities are a ...
Such an increase, coupled with a projected increment in both frequency and intensity of extreme temperature bursts (i.e. heatwaves; Robinson et al., 2021; Rogers et al., 2022; Stillman, 2019), will push many organisms outside of their optimal temperature range. Because the occurrence of ...
you may need to drink more than eight 8-ounce glasses. If you have kidney failure, urinary incontinence, or urinary frequency and can't drink that much water, ask your doctor for recommendations. When you're well-hydrated, your pee is a clear, pale yellow, so use that to guide how muc...
In sound waves, it is appreciated when the source is moving towards the observer the frequency of the sound increases, and when the source is moving away the frequency decreases.Answer and Explanation: In general when the source is moving with respect to the observer we have that the ...
