Why do planets not fall into the sun?
Space and AstronomyWhy planets do not fall into sun? The planets do not fall into the sun because they are moving too fast in the tangential direction. As they fall toward the sun they travel tangentially just enough that they never get very close to the sun. They fall around it, in effect. Why do planets don’t

Can the inverse of a relation that is not a function be a function itself?
Space and AstronomyThe inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element. (Each x and y value

How many habitable planets are there in the Milky Way galaxy?
Space and Astronomy300 million300 million.Oct 20, 2021 Is there a habitable planet in the Milky Way? A paper published in The Astronomical Journal used data from NASA’s now-retired Kepler space telescope to conclude that our galaxy holds an estimated 300 million of these potentially habitable — a rocky planet capable of supporting liquid water on its surface.

What is the relationship between the slope of the line and the side lengths of the triangles?
Space and AstronomyWhat is the relationship between the slope of the line and the side lengths of the triangle? The slope of a line can sometimes be positive or negative. However, the side lengths of each triangle formed are always positive. When a line has a negative slope, the ratio of the side lengths of the triangles

How do you find the minimum spanning tree using Kruskal’s algorithm?
Space and AstronomyCreating Minimum Spanning Tree Using Kruskal Algorithm Step 1: Sort all edges in increasing order of their edge weights. Step 2: Pick the smallest edge. Step 3: Check if the new edge creates a cycle or loop in a spanning tree. Step 4: If it doesn’t form the cycle, then include that edge in MST.

Space and Astronomymidnightclose to midnight and can be seen against a starry night sky until sunrise. When the Moon is in the Last Quarter? A week after Full Moon, the Moon reaches its Last Quarter. In this phase, the Moon is in quadrature (elongation = 270o, position G in the diagram below), and one half of the

What does triceps skinfold measure?
Space and AstronomyThe triceps skinfold is necessary for calculating the upper arm muscle circumference. Its thickness gives information about the fat reserves of the body, whereas the calculated muscle mass gives information about the protein reserves. What is triceps skin fold thickness? Skinfold thickness was measured from the left side of the body to the nearest 0.1

How do you know if an equation is rational?
Space and AstronomyWhen we have an equation where the variable is in the denominator of a quotient, that’s a rational equation. We can solve it by multiplying both sides by the denominator, but we have to look out for extraneous solutions in the process. How do you tell if an equation is rational or irrational? If you

What is the difference between achiral and chiral?
Space and AstronomyA chiral is an object that is not identically superimposable with a mirror image of itself. An achiral is an object that is identically superimposable with a mirror image of itself. What is a chiral molecule how does it differ from an achiral molecule? Chiral molecules are non-superimposable mirror images of each other. Achiral molecules
