Question

Some pieces of impurity (density = rho) is embedded in ice. This ice is floating in water (density = rho subscript w end subscript). When ice melts, level of water will

  1. fall if rho greater than rho subscript w end subscript    
  2. remain unchanged, if rho greater than rho subscript w end subscript    
  3. fall if rho greater than rho subscript w end subscript    
  4. rise if rho greater than rho subscript w end subscript    

The correct answer is: remain unchanged, if rho greater than rho subscript w end subscript


    Level will fall if initially the impurity pieces were floating along will ice and later it sinks. Level will remain unchaged if initially they were floating and later also, they keep floating

    Changing from a circular to An elliptical orbit Let us identify the system as the spacecraft and the Earth but not the portion of the fuel in the spacecraft that we use to change the orbit. In a given orbit, the mechanical energy of the spacecraft – Earth system is given by E equals negative fraction numerator G M m over denominator 2 r end fraction This energy includes the kinetic energy of the spacecraft and the potential energy associated with the gravitational force between the spacecraft and the Earth. If the rocket engines are fired, the thrust force moves the spacecraft through a displacement. As a result, the mechanical energy of the spacecraft – Earth system increases. The spacecraft has a new higher energy but is constrained to be in an orbit that includes the original starting point. It can not be in a higher energy circular orbit having a larger radius because this orbit would not contain the starting point. The only possibility is that the orbit is elliptical as shown in the figure.
