Explain Electricity and static electricity
Electricity - study of stationary (static) or moving charges
Static Electricitiy (Electrostatics) - electric charges at rest
Two types of charges: (i) negative (electrons, negative ions);
(ii) positive (protons, positive ions)
A helium nucleus and a neon nucleus are separated by a distance of 3.0 nm. The charge of the helium nucleus is +2e while that of a neon nucleus is + 10e .Find the magnitude of the
Plot the Bremsstrahlung emitted (intensity vs energy) from a copper target for (i) both 15 keV and 30 keV electrons, (ii) for 15 keV electrons at both 10 and 50 mA current and (iii
Principle of uniqueness of freefall: The idea inside general relativity that the worldline of a freefalling body is independent of its, structure, composition or state. This p
Is negative mass antimatter? No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity.
(a). Modulus of elasticity and modulus of rigidity are important parameters to measure mechanical properties of materials. With the aid of drawings, explain these parameters and gi
Work out the voltage for the following arrangement of 1.5V cells: ( Solve problems with cells in series, parallel and series-parallel)
Explain electric potential at a point due to a point charge. Write its SI unit. Derive an expression for the electric potential at a point outside a charged sphere.
What is hologram? Holography When an entity is photographed by a camera a two dimensional image of three dimensional objects is obtained. A three dimensional image of
Necessity Of A Starter For D.C Motors When motor is at rest, then N=0 and due to Eb is directly proportional to N, so At begin E b = zero Thus armature current at t
What are wave fronts? (Physics) A wave front is an imaginary surface joining all points in space that are reached at the similar instant by a wave propagating by a medium. L
