The Sun follows a (mostly) circular orbit around the center of the Milky Way with an orbital speed of 220 km s-1. The distance to the Galactic Center is a mere 26,000 light years (2.4 x 1017 km or 1.7 x 109 AU). How many years does it take the Sun to complete one full orbit around the Milky Way?

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.
