A clock shows 5 O' clock, how much angle between its minute and hour needles make ? (A) 150, (B)120, (C)100, (D)90,

An aeronautical engineer observed that on the upper and the lower surface of the wing of an aeroplane the speed of the air are 120 ms^(-1) and 90 ms^(-1) respectively during flight. What is the lift on the wing of aeroplane if its area is 3.2 m^(2) ? Given density of air is 1.29 kg//m^(3) .

An aeroplane of mass 3xx10^(4)kg and total wing area of 120 m^(2) is in a level flight at some height the difference in pressure between the upper and lower surfaces of its wings in kilo pascal is (g=10m//s^(2))

The ratio of weight of Mr .Gupta and Mrs .Gupta is 7:8 and their total weight is 120 kg .After taking the dieting course ,The weight of Mr Gupts is reduced by 6 kg and now the new ratio of their weight became 5:6 . By what amount Mrs . Gupta 's weight got reduced ?
