Charging an Electrophorus by Induction Using a Negatively Charged Object
A general physics demonstration includes the charging of an aluminum pie plate through the procedure of induction. The demonstration classically includes the subsequent steps.
• Acquire a charged object That is a balloon or Styrofoam plate made of a non-conducting material.• By Using an insulating handle on the aluminum plate, bring the aluminum plate near to but not touching the Styrofoam plate.• Touch the rim of the aluminum plate along with your finger.• Move the aluminum plate away from the charged object.
Using Gauss divergence theorem show that the volume of a sphere of radius 'r' is 4⁄3 πr 3 .
For the oscilloscope display of a pulse waveform shown in Figure, the 'time/cm' switch is on 50ms/cm and the 'volts/cm' switch is on 0.2V/cm. Verify (a) The periodic time
(i) It having of district bright bands. (ii)It is given by an excited source in molecular state. (iii) E.g. Spectra of molecular NH 3 , CO, H 2 etc.
a) Thomson's heat is proportional to the current passing by the conductor. b) This effect is produced when parts of similar conductor are kept at dissimilar temperature. c) I
Conventional Current: Earlier scientists had no knowledge of the concept of electron, so the developed the convention, still in use, , that the direction of current is for appo
For the circuit shown in Figure calculate (a) The value of resistor Rx such that the total power dissipated in the circuit is 2.5kW, and (b) The current flowing in each of th
Is it determined by acceleration or velocity? Force or momentum?
(a) State the postulate of STR and deduce Lorentz Transformation. OR Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations. (b) Pro
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
How many types of hologen and gas discharge are there? This will depend upon the use of the system. Gas discharge lamps, particularly those with a very small plasma area are pr
