Q. Why X-rays are not used in microscopes?
1) The wavelength of X-rays is slighter than that of the visible light.
2) X-rays can't be focussed as visible radiations are focussed using lenses.
3) X-rays can't be deflected by electric and magnetic fields.
When unsaturated compounds undergo addition reactions with free radicals, it is known as free radical addition reaction.
A 50 kilogram ice skater glides across the ice in a straight line at 7 meters per second. If she bends down and scoops up a 20 kilogram child standing on the ice, what will b
High resistive materials: The materials which have their resistivity 10 -8 to 10 -6 ohm-m come under this category. These materials are used for making resistance elements fo
Harmful effects of Noise: 1. Noise causes nervous tension, aggression and commotion in normal human beings. 2. Continuous noise damage hearing power and complete deafness.
Describe the magnetic moment of a bar magnet. What is its direction? Can you find two magnetic field lines intersecting? Why?
baryon decay The idea, predicted through several grand-unified theories, that class of subatomic elements called baryons (of which the nucleons protons & neutrons are members
The tree needs to fall uphill even though it is leaning downhill. The felling notch at O is sufficiently large so that the resisting moment at O is negligible. The trunk above po
How a CPH products? Answer; no time has passing of a CPH. Thus, CPH exists and never decay.
A diffraction grating used at normal incidence provides a spectral line of certain order with wavelength 6000A 0 superimpose on another spectral line of wave length 5000A 0 of th
Does weight affect how far you jump? For the same leg strength / jumping method, weight affects how far one can jump. Acceleration = Force / Mass With more mass, you can
