At a distance of 4,000 ft from the launch site, a spectator is observing a rocket being launched. If the rocket lifts off vertically and is rising at a speed of 600 ft/sec when it is at an altitude of 3,000 ft, how fast is the distance between the rocket and the spectator changing at that instant?Solution) Distance=s=√(40002+h2), rate of change of distance=ds/dt=(ds/dh)(dh/dt)=(d(√(40002+h2)/dh)(dh/dt),dh/dt=600 ft/sec
Is there any physics expert willing to write me a 6 pages paper about Bassel equation (the physics of it) illustrating that with filter examples. I need ppt slides as well to help
Do fibers have losses? Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in.
