a hohmann transfer is a fuel efficient transfer orbit to an outer planet. the process requires placing a spacecraft into an elliptical orbit about the sun, such that the perihelion, the point closest to the sun, is at the departure planet and the the aphelion, the point farthest from the sun, is at the arrival planet. the entire trajectory is depicted below.(a) Use Kepler's third law to calculate how long it would take to go from the Earth to Mars on such an orbit. (b) Can such a transfer be undertaken at any time? Explain.

In a diffraction experiment, a coherent light source illuminates a pair of identical slits in a barrier, and the resulting pattern is projected on a screen that is separated from the barrier by 2.05 m. A student sketches the pattern that appears on the screen. The locations of the centers of the bright and dark fringes are accurate, but the shading is only qualitative. The color chosen may not be an ideal match to the actual light source.
