ll The dwarf planet Praamzius is estimated to have a diameter of about 300 km and orbits the sun at a distance of 6.4 × 1012 m. What is its orbital period in years?
1.) At what distance would a satellite orbiting the Earth be geosynchronous (orbiting the Earth once every 24 hours)? It would be geosynchronous at _________ × 104 m from the center of the Earth or __________× 104 m from the Earth's surface. 2.) Hydrogen also produces spectral lines at radio wavelengths, notably at 21.1 cm. If a galaxy is moving away from us at 9% of the speed of light, at what wavelength will we detect this line? Convert this...
