Why is angular velocity negative? First definition Angular velocity is positive when the rotation is counterclockwise and negative when it is clockwise. Second definition: Angular velocity is positive when the angular displacement is increasing and negative when the angular displacement is decreasing. Does radius affect angular velocity? Linear/tangential velocity, in a circlular path, increases with […]
Is curl a vector?
Is curl a vector? In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl of a field is formally defined as the circulation density at each point of the field. A vector field whose curl is zero is called irrotational. What […]
Will 2020 be a hot summer?
Will 2020 be a hot summer? We predict summer 2020 will be warmer and drier tan average overall. We think this summer will be around 1C to 1.5C above the long term average. GWV expects all three summer months to have above average temperatures with an equal chance of July or August being the hottest […]

What is the difference between two prong and three prong outlets?
What is the difference between two prong and three prong outlets? The main difference between a two-prong outlet and a three-prong outlet is that a three-prong outlet has a ground wire, while a two-prong outlet doesn’t. Your hot wire delivers electricity to the outlet while the neutral wire sends the electricity back to the main […]
Do those or does those?
Do those or does those? Roger Woodham replies: We use do/does or is/are as question words when we want to ask yes/no questions. We use does and is with third person singular pronouns (he, she, it) and with singular noun forms. We use do and are with other personal pronouns (you, we they) and with […]
What happens if you have too much acetylcholine?
What happens if you have too much acetylcholine? Excessive accumulation of acetylcholine (ACh) at the neuromuscular junctions and synapses causes symptoms of both muscarinic and nicotinic toxicity. These include cramps, increased salivation, lacrimation, muscular weakness, paralysis, muscular fasciculation, diarrhea, and blurry vision. What gets rid of acetylcholine? One important neurotransmitter, acetylcholine, has a specialized enzyme […]
What happens to the orientation of the E in the field of view?
What happens to the orientation of the E in the field of view? Remove the slide and view the letter “e” with the naked eye. Compare the orientation of the letter “e” as viewed through the microscope with the letter “e” viewed with the naked eye on the slide. This demonstrates that in addition to […]
