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? […]

What is difference between water potential and osmotic potential? Solute potential (Ψs), also called osmotic potential, is negative in a plant cell and zero in distilled water. Because of this difference in water potential, water will move from the soil into a plant’s root cells via the process of osmosis. This is why solute potential […]

Can you see atoms using a scanning tunneling microscope? No one has ever seen an atom. The wavelength of visible light is more than 1000 times bigger than an atom, so light cannot be used to see an atom. Scanning Tunneling Microscopes work by moving a probe tip over a surface we want to image. […]
