What 3 things affect the speed of sound?

What 3 things affect the speed of sound? Factors Affecting The Speed of Sound The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in […]

Do electrons know they being observed?

Do electrons know they being observed? This process is sometimes referred to as decoherence. We also see phrases such as “wavefunction collapse”. By virtue of such an interaction of a quantum system with a classical measurement device, one could quite misleadingly assert that the electron “knows” it is being observed. It doesn’t. Why do wave […]

Is geothermal a source of electricity?

Is geothermal a source of electricity? Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity. Is geothermal energy harmful to humans? When done properly, yes.

What is B in a sine function?

What is B in a sine function? The value B is the number of cycles the graph completes in an interval of from 0 to 2π or 360º. The value B affects the period. The period of sine and cosine is. . When 0 < B < 1, the period of the function will be […]

How do you find the internal diameter?

How do you find the internal diameter? Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle. Find the total diameter of the object in question by taking a measurement from the outside wall of one side (the point of origination) straight across to the outside wall of the […]

Does cold water help hurricanes?

Does cold water help hurricanes? Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart. Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms. What weakens a hurricane? […]
