Can you diffract a human?
Can you diffract a human? Since Plank’s constant is on the order of 10-34, the de Broglie wavelength is virtually undetectable for large amounts of matter. There is much evidence of matter possessing such a de Broglie wavelength. Well, theoretically, since all matter possess wave-like properties, so do humans, and cats, and whatever you please. […]

Acids change the color of certain acid-base indicates. Acids react with active metals to yield hydrogen gas. Acids react with bases to produce a salt compound and water. How many types […]
What happens if your TYRE pressure is too low?
What happens if your TYRE pressure is too low? When air pressure gets too low, the tire’s sidewalls flex more, and heat builds up within the tire. If the overheating gets severe, a section of the tire’s rubber can separate from its carcass—the mix of fabric and steel that the tire is built on. If […]
What are the characteristics of mid-ocean ridges?
What are the characteristics of mid-ocean ridges? Principal characteristics. Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of […]
