How much money would it cost to colonize Mars?
Space and AstronomyElon Musk put an estimate to the long-term dream for SpaceX. As it stands, Musk’s dream of a permanent human settlement on Mars could be the single most-expensive construction undertaken — costing $10 trillion, one-eighth the cost of the global economy, according to a tweet from Musk. How expensive would it be to colonize Mars?
Which set or sets does the number 1 belong to?
Space and AstronomyWhat sets of numbers does 1 belong to? The number 1 is the first natural number and each natural number is formed by adding 1 to the previous one. When we subtract or divide two natural numbers the result is not necessarily a natural number, so we say that natural numbers are not closed under

Space and Astronomythe coronathe corona. What layer of the Sun is the hottest? Core Core. The hottest part of the Sun is the core, at 28,080,000°F, on average. Which part of the Sun’s atmosphere is the coolest? The photosphere is significantly cooler than temperatures at the sun’s core, which can reach about 27 million F (15 million
Who discovered the tidal theory?
Space and AstronomySir James H. JeansSir James H. Jeans (1877–1946) and Sir Harold Jeffreys. Who created the tidal theory? The tidal theory, proposed by James Jeans and Harold Jeffreys in 1918, is a variation of the planetesimal concept: it suggests that a huge tidal wave, raised on the sun by a passing star, was drawn into a
How do you integrate SEC of odd powers?
Space and AstronomyHow do you integrate SEC powers? Video quote: I 3 you'd then reuse the formula to go from I 3 2 I 1 I 1 is the integral of SEC to the power 1 the integral of SEC is a standard interval so we can do it. So for odd powers. Such as i5 or

How do you cut thick cork sheets?
Space and AstronomyIf you have thicker cork, like the kind you find in a bulletin board, the easiest way to cut it is with a utility knife. The pen-shaped thinner knives are usually best, but you can use a bigger box cutter-style utility knife if the cork is really bulky. How do you cut cork sheets? Use
Is Asa a similarity postulate?
Space and AstronomyDoes ASA prove similarity? Two triangles are similar if and only if the corresponding sides are in proportion and the corresponding angles are congruent. Just as there are specific methods for proving triangles congruent (SSS, ASA, SAS, AAS and HL), there are also specific methods that will prove triangles similar. What is ASA similarity theorem?
What is angular measure?
Space and AstronomyWhat is meant by angular measure? In geometry, an angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex. Angles are measured in degrees ( °), using a protractor. Fun Facts. The protractor was invented by Joseph Huddart in 1801. It was a
