A wave in a string has an amplitude of 2 cm. The wave travels in the +ve direction of x axis with a speed of 128 ms-1 and it is noted that 5 complete waves fit in 4m length of the string. The equation describing the wave is
The angular frequency of a particle in a progressive wave in an elastic medium is 100πrads-1 and it is moving with a velocity of 200ms-1. The phase difference between two particles separated by a distance of 20m is
A coil has 1,000 turns and 500 cm2 as its area. The plane of the coil is placed at right angles to a magnetic induction field of 2 ×10–5wb/m2. The coil is rotated through 1800 in 0.2 seconds. The average e.m.f induced in the coil, in milli-volts.
A DNA molecule is 160 base pairs long. If it has 20% adenone, how many cytosine bases are present in this DNA molecule?
Out of Rs.50,000 that a man has, he lends Rs.8000 at 5½ per annum simple interest and Rs.24,000 at 6% per annum simple interest. He lends the remaining money at a certain rate of interest so that the gets total annual interest of Rs.3680. The rate of interest per annum, at which the remaining money is lent, is
