What stages will the sun go through?
Space and AstronomyThe Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool

What is the transpose of a vector?
Space and AstronomyThe transpose of a vector is vT ∈R1×m a matrix with a single row, known as a row vector. A special case of a matrix-matrix product occurs when the two factors correspond to a row multiplying a column vector. The result is in this case a single scalar. How do you find the transpose of

Why is the moon round in shape?
Space and AstronomyThey are not perfectly round, of course, but there is a tendency for them to be nearly spherical rather than some other shape, because of gravitational attraction. A finite number of uniformly distributed particles of the same size would be attracted to each other and tend to coalesce into a spherical lump. Why does the

How do you use a sliding caliper?
Space and AstronomyHow do you use a caliper step by step? Video quote: Within the walls of the mortise as shown adjust the vernier scale until the blades of the upper jaws are flat against the walls of the mortise. Tighten the thumbscrew to fix the position. How do you read a sliding caliper? Video quote: Reading

Which flowers turn towards the sun?
Space and AstronomyFloral heliotropism. Heliotropic flowers track the Sun’s motion across the sky from east to west. Daisies or Bellis perennis close their petals at night but open in the morning light and then follow the sun as the day progresses. Do all flowers face towards the sun? It has been suggested that cloudy days cause the

Are brake caliper covers good?
Space and AstronomyThis is a commonly asked question in regard to brake caliper covers, and the simplest answer is yes, they are safe – as long as they are the proper size for your car. Most caliper covers are designed to fit nicely over your calipers to cover up any unsightly appearance while staying put and keeping

Why are geometric sequences exponential functions?
Space and AstronomyExponential functions are defined for all real numbers, and geometric sequences are defined only for positive integers. Another difference is that the base of a geometric sequence (the common ratio) can be negative, but the base of an exponential function must be positive. Is a geometric sequence exponential? Geometric sequences are the discrete version of

How big does the sun look from Mercury?
Space and AstronomyFrom the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Mercury’s surface temperatures are both extremely hot and cold. Can you see the Sun on Mercury? Why it matters — Mercury is

What do vertical lines symbolize?
Space and AstronomyVertical lines are seen as tall and represent grandeur. Horizontal and vertical lines used together in a square or rectangular shape convey structure and represent stability. Diagonal lines move the eye in a direction and indicate movement and fluidity. What do vertical lines represent? Vertical lines are strong and rigid. They can suggest stability, especially
