A velocity 1/4 m/s is resolved into two components along OA and OB making angles 30degree and 45degreerespectively with the given velocity. Then the component along OB is:
If a circle passes through the point (a, b) and cuts the circle x2 + y2 = 4 orthogonally, then the locusof its centre is????
A function y = f(x) has a second order derivative f'' = 6(x - 1). If its graph passes through the point(2, 1) and at that point the tangent to the graph is y = 3x - 5, then the function is:
Beryllium and aluminium exhibit many properties which are similar. But, the two elements differ in:(a) exhibiting maximum covalency in compounds (b) forming polymeric hydrides(c) forming covalent halides (d) exhibiting amphoteric nature in their oxides
