A bar magnet of length 6 cm is kept vertically with its north pole on the ground . If the distance of neutral point on the ground is 8 cm from the north pole , what will be the magnetic moment of that magnet ? [H=0.36 CGS units]

If a particle moves along the parabola y^2= 8x then the co-ordinates of the point on which the rate of change of abscissa is equal to the rate of change of ordinate, is

During protein synthesis in an organism at one point the process comes to a halt. Select the group o the three codons from the following, from which any one of the three could bring about this halt.

A particle P starts from the point z_0=1+2i , where i=sqrt(-1) . It moves first horizontally away from origin by 5 units and then vertically away from origin by 3 units to reach a point z_1dot From z_1 the particle moves sqrt(2) units in the direction of the vector hat i+ hat j and then it moves through an angle pi/2 in anticlockwise direction on a circle with centre at origin, to reach a point z_2dot The point z_2 is given by (a) 6+7i (b) -7+6i (c) 7+6i (d) -6+7i

Go through the following statements : (i) Lysosomes contain hydrolytic enzymes which are optimally active at the alkaline pH. (ii) A number of proteins synthesised by ribosomes on the endoplasmic reticulum are modified in the cisternae of the Golgi apparatus before they are released from its cis face. (iii) Typically a mitochondrion has a diameter of 0.2-1.0 mu m and length of 1.0 - 4.1 mu m (iv) Elaioplasts store oils and fats. Find out the correct statements
