Uses of Transistor:
In a transistor the base current it plays a significant role in the collector current IC. A small change in the base current forms a large change in the collector current. Because of this characteristic a transistor can also be used as an amplifier in more electronic devices.
What is the means in which light waves travel? Ans: Light is the only type of wave that doesn't require a medium. Confirmation that light will travel through vacuum is the

how the direction of friction is obtained?
A forced harmonic oscillator is at resonance with some periodic force. Evaluate the phase difference between the driving force and the velocity of the oscillator?
The work done by a friction force is: a) Always positive b) Always negative c) Always zero d) Either positive or negative depending upon the situation. An
A bathtub is filled to the brim with ice cold water and has an iceberg floating in it. It's a big bathtub the iceberg, of course, project above the surface of the tube when the ice
QUESTION 1 A car of mass 800 kg is pulling a trailer of mass 300 kg up the slope of angle ? to the horizontal where sine ? = 1/200. Resistance to motion (apart from gravity) is 1.
