How do we determine the conditions that existed in the early universe quizlet? How do we determine the conditions that existed in the very early universe? We work backward from current conditions to calculate what temperatures and densities must have been when the observable universe was much smaller in size. Why can’t Current theories describe […]
What are the similarities and differences between digital and analog data?
What are the similarities and differences between digital and analog data? Digital data is stored in form of bits. Analog data is stored in form of waveform signals. Digital system needs low power as compare to its analog counterpart. Analog systems consume more power than digital systems. Is digital signal immune to noise? As a […]
What occurs in a point mutation?
What occurs in a point mutation? Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the […]

Can a Tornadoes kill you? Remarkably, relatively few lives are lost to tornadoes. During an average year, tornadoes kill about 60 Americans, which is about the same number of people who killed by lightning strikes. But this is not going to be an average year. The death toll from the terrible storms in the South […]
What is mechanical efficiency is the ratio of?
What is mechanical efficiency is the ratio of? Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one. What causes low volumetric efficiency? […]
Does a mirror reflect light?
Does a mirror reflect light? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. Can you wear black in spring? Spring […]
Which of the following intermolecular forces is the strongest?
Which of the following intermolecular forces is the strongest? Ion-dipole forces What kinds of forces hold ionic solids together quizlet? What forces hold ionic solids together? Ionic bonds because ionic bonds are much stronger than any intermolecular forces. Ionic solids tend to have: Much higher melting points than molecular solids. What kind of force is […]
What are the differences between covalent and ionic bonds?
What are the differences between covalent and ionic bonds? The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between […]
