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.
Derive the mathematical expression PV r = constant for an ideal gas undergoing adiabatic reversible expansion.
There are five types of modulus of elasticity (i) YOUNG'S MODULUS OF ELASTICITY (Y (ii) BULK MODULUS OF ELASTICITY (K) (iii) COMPRESSIBILITY (iv) MODULUS OF RIGIDITY
Energy in transmitted in space in all direction. Example : Light and sound waves propagating in space.
types of lenses and their explanation
a pendulum is timed ,first for 20 swings and then for 50 swings ; time for 20 swings = 17.4 sec and time for 50 sec = 43.2. calculate the average time per swing/
LENARD ATOMIC MODEL : Lenard suggested that the atom must have a lot of empty in it. Lenard's model of an atom could not explain about the stability and mass of an atom .
When throwing a baseball, a force is exerted by the hand on the ball. a. Is this force a contact force or a field force? Contact Force b. Throwing a ball 6 m straight upwa
The Venturimeter (see figure) is a device used to calculate the flow speed of a fluid in a pipe. At the throat, the area is decreased from A to a and the velocity is increased from
