Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
A point is operating simple harmonic motion with a time period 2πs. At its mean position its speed is 0.05 m/s. Calculate its speed when it is at a distance of 0.04 m from the mean
In free space electric field intensity is provided as E= y 20 cos (ωt-50x) volt/m. Determine displacement current density.
a) Two charges of the value 15X10 -9 coulomb and 30X10 -9 coulomb are locate at a distance 6 cm. Determine the intensity of electric field at point which is at a distance 2 cm fro
Archimedes' principle A body which is submerged into a fluid is buoyed up through a force equal in magnitude to the weight of the fluid which is displaced, and directed upward
Length Contraction is Invisible This series of animations describes that the relativistic length contraction is invisible.
Reflection of a Pulse at a Free End Let's assume a pulse moving by a medium - perhaps by a rope or a slinky. What happens to the pulse while it reaches the end of in which medi
A lever of the second class Use a uniform wooden bar about 1 m long, 4 cm wide and 5 mm thick. Drill a hole near single end, in the centre of the width dimension. Also drill a
The contribution of ionic polarization takes account of the fact that when in a molecule some of the atoms have an excess positive or negative charge (resulting from the ionic char
What is the difference between the Atomic Theory and the Kinetic Theory? Atomic theory is all about structure of an atom, i.e., its composition. Like an atom in general is made
as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
