Aregion of space contains a uniform electric field oriented along the y-axis. a frame of surface area a is placed perpendicular to the y-axis in the xz-plane. the magnitude of the electric flux through this frame is φ0. a second frame is placed in the same electric field in such a way that the magnitude of the electric flux through it is φ0/2. how is the plane of second frame oriented with respect to the plane of the first one?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
