Which is the most slippery substance in the world? PTFE What fabric is slippery? When it comes to slippery fabric types, there are a few common ones: shiny satins, silks, silky polyesters, and linings are especially challenging as they tend to slide around when pinning, cutting, and stitching. Precision is important when using these kinds […]
How do you explain special relativity?
How do you explain special relativity? The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light […]
What are the two types of emission spectra?
What are the two types of emission spectra? The spectra can be divided into two types viz., emission and absorption spectra. The differences between them are given below. 1) The emission spectrum is obtained due to emission of radiation from the substances. What is most important about the emission spectra? The different colors of light […]
How many compounds can carbon form?
How many compounds can carbon form? The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things. Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or […]

Why are subtropical highs?
Why are subtropical highs? The warm air at the low latitudes rises and moves toward the poles. The rising air, and the subsequent clouds and precipitation, cause the tropics to be very wet. As the air moves towards the subtropics, it descends over the oceans and creates semi-permanent circulation features called subtropical highs. Where would […]
What weather does a cumulus cloud bring?
What weather does a cumulus cloud bring? What weather is associated with cumulus clouds? Mostly, cumulus indicates fair weather, often popping up on bright sunny days.

Can an electric eel power a light bulb?
Is 60 gigahertz harmful to humans?
Is 60 gigahertz harmful to humans? In addition to the very low power levels discussed above, 60 GHz systems do not penetrate the human body. As a result, exposure to 60 GHz is very similar to the exposure to sunlight ” but at 1/10,000 of the energy. Lower-frequency emissions penetrate and may even pass completely […]
What is the formula of urine?
What is the formula of urine? On an elemental level, human urine contains 6.87 g/L carbon, 8.12 g/L nitrogen, 8.25 g/L oxygen, and 1.51 g/L hydrogen. The exact proportions vary with individuals and with factors such as diet and health. In healthy persons, urine contains very little protein and an excess is suggestive of illness. […]
