s.i units continued

S.I. Units - The value of any physical quantity is always expressed as its numerical value as well as a unit. One often hears the weight expressed as grams or kilograms; the distance as foot, yard or mile; the volume as litres or gallons. The use of a number of un..

Inorganic Chemicals and Metals Industrial and municipal waste waters and mine run offs cause various metals and metallic compounds to be released into water. These pollutants also enter the water bodies as acid rain and their sulphate and nitrate ions make water acidic. Most inorganic ..

The S.I. unit of temperature is degrees Kelvin (K) and this scale is known as Kelvin scale. The zero point on the Kelvin scale is known as absolute zero, which is equal to -273.15C. The temperature on the Celsius scale is converted to temperature on Kelvin scale by the addition..

S.I unit of thrust is Newton (N). Now let us see whether there is a relation between the force applied (thrust) and the area on which it is acti..

Momentum - Momentum is another vector quantity which has the same direction as that of velocity. Momentum is a property of the body possessed by virtue of its mass and velocity. It is the product of mass of the body and its velocity. Momentum = mass x velocity p = m x v S.I Unit..

is parallel to the direction of electric field and for a single polar atom where ' a ' is known as atomic polarisability The dimension of ' a ' are the same as that of volume. S.I. unit of ' a ' is m 3 . Polarisation is the alignment of the dipole moments of the permanent or ind..

Just as the electric field is described as force per unit charge, electric potential at a point can be described as electrical potential energy per unit charge. This concept is useful in calculations involving energies of charged particles. Not only that, as force is related to..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric field intensity at that point is given ..

In a hospital, especially in the Intensive care unit (ICU), where seriously ill patients are treated, monitoring of the patients heart rate, blood pressure, temperature, oxygen level in blood etc. is very important. Electronic biomedical equipments continuously monitor the patie..
