What is stellar wobble?
Space and AstronomyStellar Wobble. What we measure at the telescope is a change in the wavelength in light coming from a star over the course of days, months, and years. This changing wavelength is the Doppler shift of the light, resulting from the star orbiting a common center of mass with a companion planet. How does the
How do you define parallel and perpendicular lines?
Space and AstronomyParallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle. What is parallel lines and perpendicular lines? Parallel lines are always the same distance apart for their entire length. Perpendicular lines cross each other at
Is Saturn the windiest planet?
Space and AstronomySaturn is also the ‘windiest’ planet, with atmospheric winds of up to 1600 kilometres per hour, much stronger than in the atmosphere of Jupiter. Saturn is composed mainly of hydrogen and helium. The ringed planet is nine times further away from the Sun than the Earth. Which planet is the most windy? Neptune has the
How do I install new brake calipers?
Space and AstronomyIs it easy to replace brake calipers? Brake caliper replacement is pretty simple – until you get to the bleeding part. Then you’ll need a friend (and possibly a whole lot of patience) to finish the job. Fancy bleeder tools help as well. Do you need to bleed brakes after replacing caliper? If you have

How do you get the area of a trapezoid?
Space and AstronomyTo find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2. Why is the area of a trapezoid? The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the
Which property is used in Regula Falsi method?
Space and AstronomyIn mathematics, the regula falsi, method of false position, or false position method is a very old method for solving an equation with one unknown; this method, in modified form, is still in use. What principle does Regula Falsi use? The Regula–Falsi Method is a numerical method for estimating the roots of a polynomial f(x).
How do you find the eccentricity of a circle?
Space and AstronomyEccentricity is basically the ratio of the distances of a point on the ellipse from the focus, and the directrix. If the distance of the focus from the center of the ellipse is ‘c’ and the distance of the end of the ellipse from the center is ‘a’, then eccentricity e = c/a. What is

What is the dust in interstellar?
Space and AstronomyCooper assures Murph that there is no ghost. But then there is a gigantic dust storm. The dust storms are caused by the Blight, a plague of general horror that has killed Earth’s crops. The Blight is never explained; certain theories persist that the Blight is caused by Sauron. What does the dust mean in
