At a given temperature, if the solublity product and the solublity of a sparingly soluble salt M_(2)X_(3) be K_(sp) and S . respectively, then prove that S=((K_(sp))/(108))^(1//(5)) .

From the tower 60 m high angles of depression of the top and bottom of a house are alphan and beta respectively. If the height of the house be h. then prove that h = (60sin(beta - alpha))/(cos alpha sinbeta)

The number of degress, grades and radians in an angle are respectively D,G and R. Prove that (D)/(90)=(G)/(100)=(2R)/(pi).

The first term and common difference of an A.P. are a and d respectively. If mth and nth terms of this A.P. are 1/m and 1/n respectively, then the value of (a-d) is-

L.S.D., morphine and Bhang are respectively obtained from

Mass of a body is M, its specific heat is S and temperature is T. The body is dropped in a liquid. If the mass of the liquid is m, specific heat is s and temperature is t,then prove that the final temperature of the mixture is theta=(MST+mst)/(MS+ms) . If the liquid is water then show that, S=(m(theta-t))/(M(T-theta)) .
