a jeweler claims that he sells ornaments made of pure gold. he sells a crown of 9.0n weight to a customer. in order to check purity, the clever customer measures the weight of the crown inside water and finds it to be 8.0N weight. (a) is the oranament made of pure gold=9.3 (b) in case the jeweler has mixed copper, find the mass of pure gold in the crown.

A ball A is thrown straight up from the edge of the roof of a building. Another ball B is dropped from the roof 1.00 s later. You may ignore air resistance, (a) If the height of the building is 20.0 m, what must the initial speed of ball A be if both are to hit the ground at the same time? (b) On the same graph, sketch the position and velocity of each ball as a function of time, measured from when the first ball is thrown and taken origin at the ground.

A diwali rocket moves vertically up with a constant acceleration a_(1) =20//3 m s^(-2). After sometives, its fuel gers exhausted ad then if falls freely with an acceleration a_(2) =10 m s^(-2), If themaximum height attained by the diwalin rocket is (h), using graphicalmerhod, find its speed when the fuel is just exausted. Assume h=50 m.

A beaker containing water is placed on the pan of a balance which shows a reading of M. A lump of sugar of mass m ad volume v is now suspend by a thread (from an independent support) in such a way that it is completely immersed in water without touching the beaker and without any overflow of water. How will the reading change as time passes on?
