Explain Shifting pendulums??
Get two soda water bottles that are exactly the similar size. Fill them with water and cork tightly. Place a rod across the back of two chairs. Suspend bottles as pendulums from the rod. Be sure that they are the similar length.
When two dissimilar sound rays of slightly different frequencies, traveling in a phase along the same direction, superimpose on one other, the intensity of the resultant sound at a
Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity.
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
Describe the working of the ultrasonic magnetostriction method. Working: The rod is permanently magnetized within the beginning through passing direct current. Then batter
working of deflection magnetometer
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
A 2350-kg granite tombstone absorbs 2.8 x 107 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day.

The length of a simple pendulum is about 100cm known to have a accuracy of 1mm.Its period of oscillation is 2s determined by measuring the time for 100oscillations using a clock of
The vapour pressure of a substance at 20.0 o C is 38.1 kPa and its enthalpy of vaporisation is 49.6 kJ mol -1 . Estimate the temperature at which its vapour pressure is 80.0 k
