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
Barrier potential in a P-N junction is caused by (A) Thermally generated electrons and holes. (B) Diffusion of majority carriers across the junction. (C) Migration
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
FARADAYS LAW: When the magnetic flux through the coil is made to vary, an emf is induced in the coil. The magnitude of the induced emf is proportional to the rate of change of
