What is resistance and current? Resistance is a measure of the opposition to current flow in an electrical circuit. All materials resist current flow to some degree. They fall into one of two broad categories: Conductors: Materials that offer very little resistance where electrons can move easily. What are the types of resistance? Resistor types […]
How jewelers cut and polish diamonds so they sparkle?
How jewelers cut and polish diamonds so they sparkle? As light hits a diamond, it penetrates the diamond, bounces around and reflects within the diamond and ultimately returns light to your eye. That is the sparkle that you see. The cutting of a diamond directly impacts the amount of light performance achieved. How do you […]
Is microgram bigger than MG?
Is microgram bigger than MG? In the metric system, 1000 milligrams (mg) is a unit of mass equal to 1 gram and 1000 micrograms (mcg) is equal to 1 milligram (mg) and will be the same no matter what you’re measuring. What is MG stand for? Acronym Definition mg Milligram mg Myasthenia Gravis mg Morris […]
Do lone pairs affect bond length?
Do lone pairs affect bond length? Re: Lone Pairs Affect on Bond Strength Lone Pairs of electrons on neighboring atoms weaken the bond because of electron repulsion. Neighboring atoms in a molecule that have lone pair electrons will not be held together in their bond as tightly because the lone pair electrons of both atoms […]
What happens in both mitosis and meiosis?
What happens in both mitosis and meiosis? DNA Replication Mitosis and meiosis both involve duplication of a cell’s DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content […]
What do u mean by diffraction of light?
What do u mean by diffraction of light? Diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light’s wavelength. Why do light beams diverge? Laser beams diverge because they would require an infinitely thin […]
What is a heat pump give example?
What is a heat pump give example? Heat pump is a device which pumps heat from, one or more low temperature sources to one or more high temperature sinks simultaneously, with the help of an external source of energy. The most common examples of heat pumps are air conditioners and freezers etc. Do heat pumps […]
How far is Mt Baker from Vancouver?
How far is Mt Baker from Vancouver? 69.5 miles Is Mt Baker visible from Vancouver? Located in the Mount Baker Wilderness, it is visible from much of Greater Victoria, Nanaimo, and Greater Vancouver in British Columbia, and to the south, from Seattle (and on clear days Tacoma) in Washington. Is Mt Baker dangerous? The next […]
What are the two formulas for mechanical advantage?
What are the two formulas for mechanical advantage? (b) The ideal mechanical advantage equals the length of the effort arm divided by the length of the resistance arm of a lever. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort […]
What are the four models of bonding?
What are the four models of bonding? There are four kinds of bonding types to be aware of. These are ionic , simple covalent molecular, giant covalent network and metallic. What are bonding models? A chemical bonding model is a theoretical model used to explain atomic bonding structure, molecular geometry, properties, and reactivity of physical […]
