What are the dimensions of electrical resistance ?

If a conductance of a conductor (G) is $$\displaystyle \frac { { I }^{ 2 }t }{ W } $$ , where I is current, t is time and W is work done then write the unit of conductance expressed in terms of fundamental units. 

An ice cube has a stone of 500 g placed on its top, is floating in water with its lateral sides placed vertically. It displaces 5 kg of water. Suddenly, the stone slips into water. Because of this ice cube rises by $$\displaystyle \frac{1}{10}th$$ of its length above the water level. What is the density of the ice cube (in $$kg/m^3$$)?

What is the dimensional formula of universal gravitational 'G'? The gravitational force of attraction between two objects of masses $$\displaystyle { m }_{ 1 }\quad and\quad { m }_{ 2 }$$ seperated by a distance d is given by $$\displaystyle F=\frac { G{ m }_{ 1 }{ m }_{ 2 } }{ { d }_{ 2 } } $$. Where 'G' is the universal gravitational constant.

Which one of the following defines the mass of a body?

The distance between two places is 25 km. Write the magnitude of the measurement.
