What is phyiscs
Physics is a science. Science works according to the scientific method. The scientific method accepts only reason, logic, and experimental evidence to tell among what is scientifically correct and what is not. Scientists do not simply believe - they test, and keep testing unless satisfied. Just because some "big scientist" says something is right, that thing does not become a fact of science. Unless a discovery is repeatedly established in dissimilar laboratories at dissimilar times by dissimilar people, or the similar theoretical result is derived by clear use of established rules, we do not accept it as a scientific discovery. The real strength of science lies in the fact that it continually keeps challenging itself.
Explain Resistance Resistance: Interaction among flowing charges and atoms in electric circuit which resists (slows) current flow SI units: volt per ampere ≡ ohm (Ω)
How do you calculate tensile strength? Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected
Ultra violet Waves: The wavelength of ultra violet wave from 380mm down to 60nm.
A section through a magnetic circuit of uniform cross-sectional area 2cm 2 is shown in Figure. The cast steel core has a mean length of 25cm. The air gap is 1mm wide and the
A windmill is operating in a 10 m/s wind that has a density of 1.2 kg/m 3 . The diameter of the windmill is 4 m. The constant-pressure (atmospheric) stream tube has a diameter of 3
Length Contraction is Invisible This series of animations describes that the relativistic length contraction is invisible.
Production of a magnet: Magnets can be produced in a variety of ways, generally the method used is determined by the type of magnet required. Using the stroke method
Q. On what factors does the amount of optical rotation depend? The amount of optical rotation relay on (a) Thickness of crystal (b) Density of the crystal or else concent
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
