What hazardous materials have to be dealt with while disposing the electronic items? How would these materials affect the environment?

Text Solution

Verified by Experts

When we dispose off electronic wastes, the hazardous materials in them include plastics and electronic chips made of silicon.
Such materials are non-biodegradable and will remain unchanged for a long time in the environment.

A parallel plate capacitor is to be designed with a voltage rating 1 kV, using a material of dielectric constant 3 and dielectric strength about 10^(7) Vm^(-1) . (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

(a) Obtain the de Broglie wavelength of a neutron of kinetic energy 150 eV. As you have seen in Exercise 11.31, an electron beam of this energy is suitable for crystal diffraction experiments. Would a neutron beam of the same energy be equally suitable? Explain. (m_(n) = 1.675 xx 10^(-27) kg) (b) Obtain the de Broglie wavelength associated with thermal neutrons at room temperature (27^(@)C) . Hence explain why a fast neutron beam needs to be thermalised with the environment before it can be used for neutron diffraction experiments.

Brass has a tensile strength 3.5xx10^(8) N//m^(2) . What charge density on this material will be enough to break it by electrostatic force of repulsion? How many excess electrons per square Å will there then be? What is the value of intensity just out side the surface?

Two wires are made of the same material and have the same volume. The first wire has cross sectional area A and the second wire has cross sectional area 3A. If the length of the first wire is increased by Deltal on applying a force F, how much force needed to stretch the second wire by the same amount ?
