Explain Pascals principle
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
In a series adding connection, two coupled coils have equivalent inductances LA; in a series opposing connection, LB. Determine an expression for M in terms of LA and LB. What does the outcome suggest?
Null experiment: The experiment which, after being performed, yields no outcome. The null experiments are just as significant as non-null experiments; when current theory predicts an observable result (or predicts there must be no observable result),
Kerr effect (J. Kerr; 1875): The capability of certain substances to refract light waves in a different way whose vibrations are in dissimilar directions whenever the substance is located in an electric field.
Michelson-Morley experiment (A.A. Michelson, E.W. Morley; 1887): Probably the most famous null-experiment of all time, designed to confirm the existence of the proposed "lumeniferous aether" via which light waves were considered to pr
Describe briefly all the Law of Machines?
Avogadro constant: L; NA (Count A. Avogadro; 1811) The total number of items in a sample of a substance that is equivalent to the number of molecules or atoms in a sample of an ideal gas that is at customary temperature and pressure. It is equivalent
Universal age paradox: The two most straightforward techniques of computing the age of the Universe -- via red-shift measurements, and via stellar evolution -- outcome incompatible outcomes. Recent (in mid 1990s) measurements of the distances of far-a
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Defining Aberration: The obvious change in the position of a light-emitting object due to the fidelity of the speed of light and the
