How do you find the speed of light in cooking oil? c – speed of light in vacuum; n2 – refractive index for the oil. Thus the total value of the speed of light penetrated through the glass and the oil, can be calculated according to the formula below: v3 = c/(n1*n2) = 299792/(1.5*1.33) = […]
Are cumulus clouds dangerous?
Are cumulus clouds dangerous? Thus, cumulonimbus are known to be extremely dangerous to air traffic, and it is recommended to avoid them as much as possible. Cumulonimbus can be extremely insidious, and an inattentive pilot can end up in a very dangerous situation while flying in apparently very calm air. Do pilots try to avoid […]
Do Hurricanes have eyes?
Do Hurricanes have eyes? The most recognizable feature found within a hurricane is the eye. They are found at the center and are between 20-50km in diameter. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach it. […]
How much energy is needed to completely melt a 15 g of ice?
Is Climbing stairs good for knees?
Is Climbing stairs good for knees? Stair climbing benefits Both of these large muscle groups get a workout when you climb stairs. Your own weight is enough to make stair climbing a challenge. Stair climbing also benefits the knees indirectly by helping to manage your weight. By walking up steps for just five minutes, you […]
Does viscosity depend on nature of liquid?
Does viscosity depend on nature of liquid? The viscosity is calculated in terms of the coefficient of viscosity. The value of this coefficient constant for a liquid depends on its liquid’s nature. What is the viscosity coefficient of liquid? Enter your search terms: The ratio of the shearing stress to the velocity gradient is a […]
Does a chemical reaction occur when boiling water?
Does a chemical reaction occur when boiling water? Answer and Explanation: No, boiling water is NOT a chemical reaction, but it is a physical change. When water, H2 O, is in liquid form, it can be heated to a boil. Is Steam a chemical reaction? A physical reaction causes the matter to shift shape or […]
What color dissipates heat the fastest?
What color dissipates heat the fastest? black What material stays cool in the heat? Since then, they and other researchers have made a host of materials, including films, spray paints and treated wood, that stay cool in the heat. These materials all rely on enhancing a natural heat-shedding effect known as passive radiative cooling. What […]
Does higher frequency mean better sound?
Does higher frequency mean better sound? The answer to this question is clearly no. You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels […]
