Two planets are orbiting a star in a distant galaxy. The first planet has a semi main axis of 150 *106 km, an eccentricity of0.200, and a period of 1.00 Ear years. The second planet has a semi main axis of 250*106 km and an eccentricity of0.300. What is the period of the second planet in Earth Years?
Three charged particles are arranged into a triangle. The charge on the particle located (4.0cm, 3.0cm) is 5nC. The charge on the particle at the origin is -3nC, and the change on the particle located at (4.0cm, 0cm) is +6nC. Determine the magnitu..
