t bar t construction

It consists of N turns of coil PQRS wound over a non-magnetic metallic frame usually rectangular or circular. The coil is suspended from a torsion head H by means of phosphor bronze strip in a magnetic pole by pieces N and S. A mirror M is attached to the phosphor bronze strip. The other end of th..

To construct a perpendicular to a line from a point outside it A line AB and a point O outside it. It is required to construct a perpendicular to AB from O. (i) With O as centre, taking any suitable radius, draw an arc to cut AB at S and T. (ii) With S and T ..

To construct a perpendicular to a line at a point on it A line AB and a point O on it. A perpendicular to AB at O. (i) With O as centre and any suitable radius, draw arcs to cut AB at points S and T. (ii) Take radius equal to more than half the length of ST. (iii) With this radi..

>(iii) With S as centre and radius equal to DE draw an arc to cut this arc at T. (iv) Join QT and produce it to ..

It is the time taken by the particle executing SHM, to complete one oscillation i.e., a to and fro motion. It will be equal to the time taken by the body to complete one revolution or the circle of referen..

The killer T - cells destroy the foreign antigens. They also destroy cancer cells. They are stimulated to destroy the non - self cells with the help of the helper T - cel..

It is the step in which the amino acid AMP-enzyme complex joins with the amino acid binding site of its specific tRNA, where its COOH group bonds with the OH group of the terminal base triplet CCA. The reaction is catalyzed by the same enzyme, aminoacyl tRNA synthetase. The resu..

The tRNA carries a specific amino acid from the amino acid pool to the mRNA on the ribosomes to form a polypeptide, hence its name. The tRNAs form about 15% of the total RNA of a cell. Its molecule is the smallest and has the form of a cloverleaf. It has four regions: Carrier..

Let us now see the nature of the v - t graph for the different types of motion. a) Increasing acceleration Uniform Acceleration -------------------------------- Non-uniform Acceleration b) Decreasing acceleration Non-uniform Retardation ---------------------------- Uniform Reta..
