Let O be the vertex and Q be any point on the parabola,x2=8y. It the point P divides the line segment OQ internally in the ratio 1 : 3, then the locus of P is :
The equation of the plane containing the line 2x−5y+z=3;x+y+4z=5, and parallel to the plane, x+3y+6z=1, is :
If m is the A.M. of two distinct real numbers land n(l,n>1)andG1,G2 and G3 are three geometric means between land n, then G14+2G24+G34equals,
3 g of activated charcoal was added to 50 mL. of acetic acid solution (0.06N) in a flask. After an hour it was filtered and the strength of the filtrate was found to be 0.042 N. The amount of acetic acid adsorbed (per gram of charcoal) is :
