Q What is photoelectric effect?
Photoelectric release is the phenomena by which a good number of substances chiefly metals emit electrons under the influence of radiation such as X-rays, γ rays, ultraviolet and even visible light.
The minimum real charge on any particle which can exist is: (1)1.6x 10 -19 coulomb (2) 1.6x 10 -10 coulomb (3)4.8 x 10 -10 coulomb (4)Zero Ans: (1)1.6x 10 -19 c
Ripple tank The concept of reflection and refraction of light waves can be understood by the study of reflection and refraction of waves on water. The water waves travel
Two travelling sinusoidal waves are described by the wave functions Y 1 = 55.00 sin [π (4.00 x - 1200 t )] Y 2 =55.00 sin [π (4.00 x - 1200 t - 0.250)] Where x ,
an object of mass 5.0 Kilograms initially travelling at 12.0m/s horizontally enters a region where there is a coefficient of kinetic friction of 0.27. a) use the concepts of wor

Q. What is microwave oven? How it works? Microwave oven It is utilized to cook the food in a short time. When the oven is manage the microwaves are generated which in turn
It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.
what is inertia?
A large model rocket engine can make a thrust of 12.0 N upon ignition. This engine is part of a rocket with a total mass of 0.288 kg when launched. a) Draw a free-body
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) momentum but not energy b) neither moment
