Technician a says that many bearings also have a thin overlay of babbitt. technician b says that bearings should have spread and crush to keep them from spinning when the crankshaft rotates. which technician is correct?

tube or goog with be a great resource to with that question

positive reinforcement? ?

like poles repel so keep pushing north to north and repels funny to see this

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
