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.
Explain the term 'work function' of a metal. The threshold frequency of a metal is f 0 . When the light of frequency 2f 0 is incident on the metal plate, the maximum velocity of e
If a proton and an electron have same de Broglie wavelength, which has more kinetic energy and momentum?
Direct Current (DC): Such a current can be getting by connecting the two ends of a conductor to the terminals of the battery. This current doesn't change the direction

Q. Define roentgen and activity and Curie? One roentgen (1R) is described as the quantity of radiation which produces 1.6 × 10 12 pairs of ions in 1 gram of air. The activi
Free-particle A. Suppose that the wavefunction for a free-particle is given by the wavefunction Find the value of A that normalizes Ψ (x). B. The Hamiltonian oper
Brass: When copper is alloyed zinc (60% copper, 40% zinc) is called brass. It is widely used as a current carrying and structural material in switches and plugs etc. Propertie
An atom of argon(18 protons, 19 neutrons) is ionised by the removal of two orbiting electrons. Q) How many protons and neutrons are there in this ion?
A constant potential difference is applied across the plates of a parallel-plate capacitor. Neglecting any edge effects, the electric field inside the capacitor is: a) constan
