A ball starts from rest and accelerates at 0.470 m/s2 while moving down an inclined plane 8.90 m long. When it reaches the bottom, the ball rolls up another plane, where, after moving 15.20 m, it comes to rest. (a) What is the speed of the ball at the bottom of the first plane? m/s (b) How long does it take to roll down the first plane? s (c) What is the magnitude of the acceleration along the second plane? m/s2 (d) What is the ball's speed 8.30 m along the second plane? m/s

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
