It is the hindrance to the passage of current. It is the ratio of potential difference (V) across the conductor to the current (I) flowing through it. It is expressed in Ohm or W ..

To show that f = R/2 where f is the focal length of a mirror and R its radius of curvatu..

The magnitude and unit of 'R' depends upon the units in which pressure, volume and temperature are expresse..

Radius of curvature (R) is the radius of the sphere of which the mirror is a par..

The rRNA molecule is greatly coiled. In combination with proteins, it forms the small and large subunits of the ribosomes, hence its name. It forms about 80% of the total RNA of a cell. A eukaryotic ribosome is 80S; with a large 60S subunit consists of 28S, 5.8S and 5S rRNAs an..

R.D = Since weight is proportional to mass R.D When a body is immersed in water, it displaces its own volume of water. Upthrust on the body is equal to the weight of this displaced volume of water, which is also equal to loss of weight of the body. Hence 'weight of eq..

These are species with small populations in the world. They are confined to limited areas or are thinly distributed over a more wide area. They are not at present endangered and vulnerable but are at risk. Example: Two species of Asiatic pheasa..

The angle which the refracted ray makes with the normal at the point of incidence, is called angle of refractio..

R and S Notation of Optical Isomers - The scheme of representing optical isomers using the prefix R (derived from Greek word Rectus) and prefix S (derived from Greek Sinister) was proposed by R.S.Cahn, C.K.Ingold and V.Prel..
