What is the difference between equal and congruent angles?
Space and AstronomyIf some attributes of geometric figures are the same in magnitude, then they are said to be equal. If both the sizes and the figures are equal, then the figures are said to be congruent. Equality concerns the magnitude (numbers) while congruence concerns both the shape and the size of a figure. Do equal and

What is a caliper on car?
Space and AstronomyA caliper is part of the disc brake system, the type most cars have in their front brakes. The brake caliper houses your car’s brake pads and pistons. Its job is to slow the car’s wheels by creating friction with the brake rotors. How much does it cost to replace calipers? Front calipers cost between

How many habitable planets are there?
Space and AstronomyOctober 29, 2020, Mountain View, CA – Thanks to new research using data from the Kepler space telescope, it’s estimated that there could be as many as 300 million potentially habitable planets in our galaxy. Some could even be pretty close, with several likely within 30 light-years of our Sun. How many possible habitable planets

How hot is it in the center of the Earth?
Space and Astronomy10,800 degrees Fahrenheit10,800 degrees Fahrenheit. How long will the Center of the Earth stay hot? However, if the heat is created mostly in part due to radioactive decay, then the Earth’s heat will likely last much longer. While that sounds pretty alarming, some estimates for the cooling of Earth’s core see it taking tens of

When two lines intersect any two nonadjacent angles formed by those lines are called?
Space and AstronomyTwo nonadjacent angles formed by two intersecting lines are vertical angles. When two lines intersect any two nonadjacent angles formed are called? Vertical angles are two nonadjacent angles formed by two intersecting lines. Are the two nonadjacent angles formed by two intersecting lines these angles are congruent? The nonadjacent angles formed by two intersecting lines.

Why do single dish radio telescopes have poor resolution?
Space and AstronomyWhy do single-dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter? Because the size of diffraction fringes is proportional to the wavelength of light being focused, and radio waves have longer wavelengths than visible light. Why do radio telescopes have low resolution? . Radio waves have a large wavelength

Why is a rational function not a polynomial?
Space and AstronomyAny rational function r(x) = , where q(x) is not the zero polynomial. Because by definition a rational function may have a variable in its denominator, the domain and range of rational functions do not usually contain all the real numbers. Is a rational function a polynomial? Just as rational numbers are defined in terms

What is stellar parallax and how do astronomers use it?
Space and AstronomyAstronomers use an effect called parallax to measure distances to nearby stars. Parallax is the apparent displacement of an object because of a change in the observer’s point of view. What is stellar parallax and how do astronomers use it quizlet? What is Stellar parallax? It is the slight back-and-forth shifting of star positions that
