What happens when inductor is connected for a long time? If you wait long enough, the current in an RL circuit stops changing! At t=0, a capacitor acts like a wire; an inductor acts like a broken wire. After a long time, a capacitor acts like a broken wire, and inductor acts like a wire. […]

Which element is a liquid at 1000 K? aluminium What called liquid? A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), […]

What are the 4 types of hypersensitivity? The four types of hypersensitivity are: Type I: reaction mediated by IgE antibodies. Type II: cytotoxic reaction mediated by IgG or IgM antibodies. Type III: reaction mediated by immune complexes. Type IV: delayed reaction mediated by cellular response. What is an example of delayed hypersensitivity? Examples of DTH […]

What is a line plan? A line plan defines when a style is going to be loaded to the line, how many pieces to be expected (target) from the line and when an order to be completed. What is the best cell phone plan for 3 lines? Family Plans Mint Mobile 20. DISH. • /person. […]

How much power does a lift take? The elevator controller uses about 83 watts all the time, even when the elevator is idle. That’s about $130 per year without even moving! Going up uses almost 40 times as much power as going down. Going up 5 floors uses about 500 kilowatt seconds and costs about […]

Is it freefall or free fall? verb (used without object), free-fell, free-fall·en, free-fall·ing. (of parachutists) to descend initially, as for a designated interval, in a free fall: The jumpers were required to free-fall for eight seconds. How do you breathe in free fall? It’s often believed that you can’t breathe during a skydive, but this […]

What unit does NASA use? NASA has ostensibly used the metric system since about 1990, the statement said, but English units are still employed on some missions, and a few projects use both. NASA uses both English and metric aboard the International Space Station. Did NASA always use the metric system? Although NASA has ostensibly […]

Is P value and power the same? rests on the same idea that I reject : power and p-values measure the same thing. A statistical test contrasts two mutually exclusive propositions: H0 (the null hypothesis) and H1 (the alternative hypothesis). What does a correlation of 0.01 mean? The tables (or Excel) will tell you, for […]

IS 144 a perfect number? 144 is a perfect square, sure, but the sum of its digits is also a perfect square (9), the product of its digits is also a perfect square (16), and its reverse is also a perfect square (441). 144 can be written as the sum of two twin primes, namely […]

What type of reaction is potassium hydroxide and sulfuric acid? In a neutralization reaction between an acid and a base the typical outcome is a salt formed by the positive ion from the base and the negative ion from the acid. In this case the positive potassium ion ( K+ ) and the polyatomic sulfate […]
