G has the value of 6.67 x 10-8 dyne * cm2/gm2. So if you put two 1-gram objects 1 centimeter apart from one another, they will attract each other with the force of 6.67 x 10-8 dyne. A dyne is equal to about 0.001 gram weight, meaning that if you have a dyne of force avai...
(If you must, seeHow to Calculate the Coefficient of Determination). There are many statistical packages that can calculated adjusted r squared for you. Adjusted r squared is given as part of Excel regression output. See:Excel regression analysis output explained. Meaning of Adjusted R2 Both R2...
What is 1−cos2(x) equal to? Trigonometric Identities:Trigonometric identities are equations that involve trigonometric functions. They are always true for every value of the variable where the functions on both sides of the equation are defined. They are often used in solving geometry problems ...
What is 75 squared? What is molar conversion? What is climate? What is -12 -(-9) equal to? What is volume? What is an autotriploid? What is geometry ? What is the fraction of 8%? What is 92% as a fraction? How many acres are in a square mile? 30 is what percent of 40?
Not all calories are created equal. What we mean by that is that 100 calories of almonds don’t affect your weight in the same way as 100 calories of nachos. Your body has to work harder to digest foods that are rich in fiber and protein than it does to digest refined carbohydrates, ...
The American conversation about high-speed rail has an internal debate that greatly bothers me, about whether investments should be incremental or not. An interview with the author of a new book about the Northeast Corridor reminded me of this; this is n
Rectangle is a quadrilateral in which all 4 angles are right angles; opposite sides parallel and equal. Learn properties, formulas for area and perimeter & more.
A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.Looking around, you can find many things that resemble the square shape. Common examples...
This conjecture asserts that a Kakeya set – a subset of that contains a unit line segment in every direction, must have Minkowski and Hausdorff dimension equal to three. (There is also a stronger “maximal function” version of this conjecture that remains open at present, although the ...
Surfaces and perspective are the key to an argument for realism. We show that there is plenty of information around us in the natural world for surfaces and the cornucopia allows us to experience our earthly environment accurately. Far afield, the same goes even for the Moon and Mars—...
