A mechanical press is used to mold shapes of plastic toys. It produces 8% defective toys. In a lot of 100, determine if p ˆ can be approximated by a random variable. If yes, find the values of μ p ˆ , σ p ˆ . => Yes, 8, 2.71 or Yes, 0.92, 0.027 or No or Yes, 0.08, ..

Wave nature of material objects In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Broglie's relation as: ..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of the quantu..
