How High Will It Go?
The motion of the sledder within the animation below is same to the motion of a roller coaster car on a roller coaster track. The similarity of the two motions is related along with the work-energy relationship. The energy bar charts accompanying the animation depict this relationship. Energy bar charts are a conceptual tool amount the amount of each form of energy possessed through an object as it is undergoes a particular motion. Observe from the animation in which the total mechanical energy TME of the sledder remains constant by the motion.
Some phenomenon based on scattering: (i) Sky looks blue because of scattering. (ii) At the starting time of sunrise or sunset sun looks reddish. (iii) Danger signals are

Explain how receiver functions in fibre optic communication system. Receiver: The optical signal received must be first converted within digital form and in case analog outp
Superfluidity: The phenomena through which, at sufficiently low temperatures, a fluid can flow along zero viscosity. Its causes are related with superconductivity.
The natural angular frequency of a S.H.O. of mass 2gm is 0.8rad/sec. It undergoes critically damped motion when taken to a viscous medium. Evaluate the damping force on the oscilla
Doping: Silicon and Germanium have low values of electrical conductivity because of few free electrons. In order to improve the electrical conductivity of semi conductors' pent
