DUE TO SURFACE TENSION WATER MOLECULES TEND TO HAVE MINIMUM SURFACE AREA AND SPHERE HAS THE MINIMUM SURFACE AREA FOR A GIVEN VOLUME AND THEREFORE BUBBLES ARE IN SPHERICAL SHAPE ONLY.
Hard Ferromagnetic Substances: Those substances that do not lose their magnetism or removing from magnetic field are known as hard magnetic substance such as steel.
Illustrates some way to by which ultrasonic waves propagated? Detection of Ultrasonic Waves: Ultrasonic waves propagated by a medium can be detected within a number of ways.
If the distance between the earth and moon were halved, the force of the attraction between them would be: a) One fourth as great b) One half as great c) Twice as g
The average speed of a substance in a given interval of time is explained as the ratio of the distance done to the time taken whereas; average velocity is explained as the ratio of
If a traveling wave is a sin or cos function of (x± vt) the wave than it is said to be harmonic or plane progressive wave.
Q. The half life of radon is 3.8 days. Calculate mean life. Half Life Period HLP T ½ = 0.6931 / λ = 0.6931 τ therefore Mean life τ = T ½ / 0.
Find the value of g by free fall method.
a beam of electron is incident on barrier 6eV high and 0.2 nm wide. find the energy in eV these should have if 1% of them are to get through the barrier.
Explain the term 'resistivity' and write its S. I . unit. Derive the expression for the resistivity of a conductor in terms of number density of free electrons and relaxation time.
10 moles of an ideal gas expands reversibly and isothermally from a volume if 5 lit. to 50 lit. at 25°C. Find the maximum work done? Express the result in Joules.
The Bubble''''s shape is spherical so as to reduce the surface tension. With the given volume of liquid,Spherical surface only fits i minimizing tthe surface tension to a greater extent than other shapes viz. cylindrical,cubical etc. and hence the shape is spherical
