Do sunspots appear in pairs?
Space and AstronomySunspots generally appear in opposite-polarity pairs or in opposite-polarity groups when the magnetic field is fractured. Why do sunspots occur in pairs? Apparently, the sunspot pairs represent points where the internal magnetic field penetrates the surface at one spot and re-enters at the other. All the sunspot pairs in a given hemisphere, north or south,
How do you calibrate a dial caliper?
Space and AstronomyHow do you calibrate a caliper? Video quote: The first test is with the outside measuring faces for 6-inch caliper the ASME standard requires a minimum of three points across the measuring range the minimum then increases for larger calipers. How do you check to see if a dial caliper is calibrated? Calibrate for specific
What is the use of infinity mirror?
Space and AstronomyInfinity Mirrors are designed to give the illusion that the lights within them are trailing off into the abyss, continuing on forever into infinity and beyond. This is achieved through the placement of your LED lights between the two glass mirror panels. Where are infinity mirrors used? Some commercial applications also use infinity mirror. This

How do you find the period of a wave in pre calc?
Space and AstronomyThe period of the function can be calculated using 2π|b| 2 π | b | . Replace b b with 3 3 in the formula for period. The absolute value is the distance between a number and zero. The distance between 0 0 and 3 3 is 3 3 . How do you find the

Space and AstronomyA vector quantity has a direction and a magnitude, while a scalar quantity only has magnitude. Examples: Scalar quantity include things like speed, time, volume, mass and temperature, while Vector quantities include things like acceleration, velocity, force, momentum and the increase and decrease in temperature. What is scalar and vector give examples? Scalars are the
