How do the largest radio telescopes compare to the largest optical telescopes?
Space and AstronomyRadio telescopes have to be much larger than optical telescopes because the wavelengths of radio waves are so much larger than the wavelengths of visible light. Radio wavelengths are between λ ≈ 3 km to λ ≈ 1 cm, while visible light wavelengths are between λ ≈ 4 x 10–7m (violet) and λ ≈ 7

What type of graph is used for discrete data?
Space and AstronomyDiscrete data is best represented using bar charts. Temperature graphs would usually be line graphs because the data is continuous . When you are graphing percentages of a distribution a pie chart would be suitable. What is discrete data in graphs? Discrete data is a collection of individual, unconnected points. Discrete graphs are made of

Where does the anti rattle clip go?
Space and AstronomyThe anti rattle clips are in between the pad and caliper bracket. You can clearly see them in your second picture. The tabs on the end of pads are in them. What you pictured are the clips that come into contact with the rotor before the pad material runs out to let you know the

What is x0 in calculus?
Space and AstronomyThe notation x → x0 is read as “x approaches x0.” The quantity represented by ( eq:notlim. 2-1) is a single number, if the limit exists. For many simple functions the limit is just the function value f(x0). What is x0 in derivative? Slope and derivative As x approaches xo, the secant line becomes the

What was the climax of hidden figures?
Space and AstronomyThe film’s climax comes when Glenn becomes the first American to orbit the Earth — even though the historic trajectory was calculated by electronic computers, he insisted that Johnson check the computer’s numbers personally beforehand, the show’s producers said. What is the climax or moment of highest tension Hidden Figures? The climax of the film

Where are convex mirrors located?
Space and AstronomyConvex mirrors are also often found in the hallway of various buildings including hospitals, hotels, schools, stores and apartment building. Usually, these mirrors are mounted to a wall or ceiling at points where hallways cross each other or make a sharp turn. Where can you find concave mirrors? Some concave mirror uses are listed in

What is a ? B?
Space and AstronomyA/B testing is a way to compare two versions of a single variable, typically by testing a subject’s response to variant A against variant B, and determining which of the two variants is more effective. What is B minus grade? B − Good. Conditional, not fully satisfactory. What percentage is a B? 70% to 74%

What planet has the strongest greenhouse effect?
Space and AstronomyVenusVenus. Venus is similar to Earth in terms of size and mass, but its surface temperature is about 460 degrees Celsius. This is hot enough to melt lead! The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas. Which planet is the hottest because of the greenhouse effect? Venus Venus is the

How do you subtract expressions?
Space and AstronomyA rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same. How do we
