Due to the Doppler effect which states that there is a change in frequency because of the relative speeds of two bodies time dilation takes place. For light the relative difference in velocity between the observer and the source needs to be considered.
Time dilation is the phenomenon where time flows differently for two bodies having different to each other. Time dilation has been verified by the readings of the satellite navigation systems.
Δt' = Time elapsed of a moving body
Δt = Time elapsed when the body is stationary
v = Velocity of the moving body
c = Speed of light
As, v is always less than c, Δt' will always be greater than Δt. This means that more time has elapsed for the body in motion.
Hence, the clock in motion will be faster than an identical clock at rest.
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid.
This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge. This helps water dissociate ionic compounds into their positive and negative ions.
A bolt of lightning<span>, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case, its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit) </span><span>So,it can be around 30,000 degrees.The answer is Choice A.</span>
