Acube of side 5cm is placed in a fluid. for the following velocity values, calculate the average divergence of the flow. is there a source or sink within this box? the velocities are given in cm/s. the cube is oriented so that the +z axis exits the front face, the +x axis exits the right face and the +y axis exits the top face. front. vr=30i+60j-30k right v 20i-20j+20 left v-100i+200j+300k ^ ^ top-5+ 50+ 10k bottom vbe0 back vb. =250k also draw a diagram showing these velocities.

Why do electron microscopes have higher resolving power than light microscopes?

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.
