It having of a Cu plate coated with a thin layer of cuprous oxide (Cu2O). On this plate is laid a semi transparent thin film of silver.
When light fall, the electrons emitted from the layer of Cu2O and move towards the silver layer. Then the silver layer changes into negatively charged and copper plate become positively charged. A potential dissimilarity is set up among these two and current is set up in the external resistance.
Using a wheel and axle Use the pencil sharpener that you used in experiment A 8. Pull on the end of the string that held the books and observe how rapidly the crank turns.
A rocket weighs 9800N. What applied force gives it a vertical acceleration of 4m/sec/sec?

Q. Find the electric potential at a distance 0.09 m from a charge of 4 X 10 -7 C. The electric potential V = ( 1/4πεo ) q /r = ( 9 X 10 9 X 4 X 10 -7 )/ 9 X 10 -2 = 4 X 10
How we can calculate the magnitude of electric field above a sheet charged with voltage V where we know the bulk conductivity and relative permittivity of the space above the sheet
An aluminum rod at a temperature of 100 o Celsius radiates energy at a rate of 10 watts. If its temperature is enhanced to 200 o Celsius, at approximately what rate will it radia
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
