Which element has a mass of 24? Chromium Why are lanthanides Coloured? Lanthanides or more precisely lanthanides ions are coloured mainly because of their partly filled f orbitals. This allows a certain wavelength from the visible region of the spectrum to be absorbed which leads to the formation of f-f transition. Is lanthanides are Colourless? […]

Is jumping a normal force? When we jump, the chemical energy in our muscles get converted to kinetic energy that exerts a force on the ground (that using Newton’s 3rd law), will trigger a reaction that will ‘push’ us up- and thus a jump. This resultant normal force = Mass x Distance of jump. Is […]

What is the angle of reflection if the angle of incidence is 30 degree? Explanation: The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 – 30 = 60 degrees. What […]

What happens to air pressure as altitude decreases quizlet? As air pressure decreases altitude increases. As air pressure decreases so does density. What happens to air pressure and density as altitude increases? Altitude and Density The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down […]

Is 1.21 gigawatts alot? Sure, that’s a lot of power but actually not a lot of energy. 1.21 gigawatts delivered in 50 microseconds is only about 60,500 Joules, or 14 kilocalories of energy. Which is the amount of energy in…a cucumber. Is it possible to get 1.21 gigawatts? To get 1.21GW you would therefore require […]

Is a 32 inch vertical good? A very good jump would be in the 28- to 32-inch range. An athlete with an excellent vertical jump would rise 32 to 36 inches. Anything above 36 inches would put a high school athlete at the top of his class. What happens to the body when you jump? […]
