What was the first step in the formation of the solar system? Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar […]
Which is the most slippery substance in the world?
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 […]
Are transuranium elements synthetic?
Are transuranium elements synthetic? Producing Transuranium Elements Transuranium elements that can be found on Earth now are artificially-generated, synthetic elements made via nuclear reactors or particle accelerators. The half-lives of these elements show a general trend of decreasing as atomic numbers increase. What are synthetic elements used for? Uses of some Synthetic Elements Technetium is […]
What is shutdown dissociation?
What is shutdown dissociation? The Shutdown Dissociation Scale (Shut-D) is a semi-structured interview, it was first published in 2011 to assess dissociative responses caused by reminders of traumatic stress .[1] The Shut-D Scale assesses biological symptoms associated with freeze, fight/flight, fright, and flag/faint responses, and is based on the … How can you tell if […]
What happens in a catalyzed reaction?
What happens in a catalyzed reaction? To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme’s substrates. In some reactions, one substrate is broken down into multiple products. The reaction then occurs, converting the substrate into products and forming an enzyme products complex. What […]
What is survival of the fittest examples?
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 […]
