Van der Waals force (J.D. van der Waals):
It is the forces which is responsible for the non-ideal behavior of gases, & lattice energy of molecular crystals. There are three causes: dipole-induced dipole moments; dipole-dipole interaction; and dispersion forces arising due to small instantaneous dipoles in atoms.
singularity: The center of a black hole, where the curvature of spacetime is maximum. At the singularity, the gravitational tides diverge; no solid object can even theoretical
Analogue multimeter: Even the most basic analogue multimeter can prove to be invaluable when in the hands of an experienced user. Simple measurements of voltage, current and r
A satellite of mass "M" is in orbit around the earth. If a second satellite of mass "2M" is to be placed in the similar orbit, the second satellite must have a velocity which i
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
