Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
Describe binding energy. How does binding energy per nucleon vary with mass number? What is it significance.
Q. Why does the sky appear blue in colour? As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look o

Q. Illustrate what is a thermal transformation? Answer:- Chemical or else physical changes are not requiring a change in the temperature of the substance as in the formati
a projectile is fired from a gun has an initial velocity of 90.0 Km/h at an angle of 60.0 degrees to the horizontal. When the projectile is at top of its trajectory an internal exp
RANGE OF PROJECTILE: "It is the horizontal distance covered by the projectile from the point of projection to the point where it returns to its level of projection".
explain and illustrate how pure spectrum is formed
A bicycle is supported so that it is stopped from falling sideways but can move forwards or backwards; its pedals are in their highest and lowest positions. A student crouches
When hydrogen atom is excited, it returns to its normal unexcited (or ground state) state by emitting the energy it had absorbed previous. This energy is given out by the atom in t
In 1993, Ileana Salvador of Italy walked 3.0 km in under 12.0 min. Suppose that during 115 m of her walk Slavador is observed to steadily increase her speed from 4.20 m/s to 5.00 m
