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 […]
What is the probability of drawing a blue marble from a bag of 18 marbles three of which are blue?
What is the probability of drawing a blue marble from a bag of 18 marbles three of which are blue? The probability is 3/18 which you can simplify down to 1/6. 🙂 Hope this helps! What is without replacement in probability? Probability without replacement means once we draw an item, then we do not replace […]
What is the thermoelectric power?

What was the first plane to break sound barrier?
What was the first plane to break sound barrier? Bell X-1 Did Spitfire break sound barrier? A Spitfire very nearly broke the sound barrier in 1944. In the 1930s a small number of aero-engineers recognized that the piston-engine and propeller were providing diminishing returns. For the aircraft to go supersonic the whole propeller would have […]

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? […]
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. As with any industrial project there are risks involved, but when […]
