1. The picture below shows a double pulley system where the 4kg mass is wound on the bigger groove(r2) and the 6kg mass is wound on the smaller groove(ri) with half the radius as the bigger one(r2-2r1). However, both the grooves of the pulley are fixed to each other and can only rotate together. The mass of the pulley is 8kg. What is the acceleration of the 4kg mass? Specify the direction as well.

Select Tru or False. 1. A conducting sphere with charge Q at equilibrium has zero E field inside it. The E field outside is the same as that of a point charge Q, E=keQ/r2. The potential outside it is the same as that of a point charge Q. V= keQ/r. (r is the distance to the center). The potential inside the conducting sphere is equal to the potential at its surface. V= keQ/R. (R is the radius of the sphere)...

The Campus Collective company, which creates unique apps for colleges, has recently lost three large university clients that made up 40% of its total revenue. This has hit the company hard and management finds it necessary to reduce staff or wages. The economy also appears to be headed toward a recession and gaining more clients will most likely be harder to accomplish. Because it is a smaller company everyone knows each other and knows there are tough choices ahead. Management...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...
