Draw the electric field figure as viewed by a person positioned on the positive x-axis who is looking back toward the origin for the case of an electric field characterized by the electric potential
Feedback:
, and yield for the given V
Ex = -5.00 volts/meter
Ey = 0 and
Ez = 0.
Therefore the electric field everywhere is in the negative x direction.
Factors which are affect velocity of sound in gaseous medium is (1) Effect of density (2) Effect of pressure (3) Effect of temperature : (4) Effect of humidity
Explain physically how a p-n junction functions as a rectifier. Ans: When a P-N junction diode is forward-biased and applied voltage is increased from zero, hardly any current
What is Equipotential Surface Equipotential Surface - surface of constant potential. No work is required in moving charges with such a surface. Electric fields are perpend
Explain the Energy and Power in Circuits Electrical power dissipated in a circuit or a single circuit element can be calculated using P = I V where power (P) is in wa
Explain about the term simulated absorption in brief. Stimulated absorption: a. For the photon-atom interaction to happen, the energy of the interacting photon h? must match
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
Experiment with wat er Suspend a tin can about 8 cm deep and 12 cm in diameter as shown in the diagram. Pour about 3 cm of water into the can and twist the drill. Observe what
INERTIAL FRAME OF REFERENCE: "A frame of reference which is not being accelerated and it might be at rest or moving with uniform velocity is known as inertial frame of referen
(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.
(Assume the metallic ball is spherical with a diameter d = 2.5 cm. Let''s also assume it is made out of nickel, which has a density of roughly 9 g/cm 3 .) After it first touches
