Show that the points P" "(-2," "3," "5) , Q" "(1," "2," "3) and R (7," "0," "-1) are collinear.

Bird is flying in north-east direction with v= 4sqrt2 m/s with respect to the wind and the wind is blowing from north to south with speed 1 m/s. Find the magnitude of the displacement of bird in 3 sec.

The atomic Number (2) of an element is '25' in it's ground state, how many electrons are present in 'N' shell is 1 4 O 3 O 2

A bird is sitting on the top of a vertical pole 20 m high and its elevation from a point O on the ground is 45o . It flies off horizontally straight away from the point O. After one second, the elevation of the bird from O is reduced to 30o . Then the speed (in m/s) of the bird is (1) 40(sqrt(2)-1) (2) 40(sqrt(3)-2) (3) 20""sqrt(2) (4) 20(sqrt(3)-1)
