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?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
