While traveling in a train at half the speed of light, you notice time slowing and distances shrinking outside. Your friend on the platform notices your clock ticking slower and the train appearing shorter. Both perspectives, based on relativity, reveal the dramatic effects of traveling at such high speeds, demonstrating time dilation and length contraction, … Read more

The viscosity of a fluid is to be measured by a viscometer constructed of two 5 ft-long concentric cylinders. The inner diameter of the outer cylinder is 6 inches. The gap between the two cylinders is 0.035 inch. and the gap is filled with fluid. The outer cylinder rotates at 250 rpm, and the torque is measured … Read more
