1. State Newton’s law of geravitation. The massess of two heavenly bodies are 2×1016 kg and 4×1022 kg respectively and the distance between them is 3000 km, find out the gravitational force between them.

2. How is electrical energy obtained from the geothermal energy? Expalin in brief. Write down the suitable conditions for nuclear fusion reaction that occurs in the sun. give one example of non-renewable energy resource?

3. Define one Pascal pressure. Why hydraulic systems are knows as “force multipliers” Which one of the following figure is salt solution? Why?

4. State Pascal’s law.Which principle does Hydrometer based on? Acceleration due to gravity of any place is 9.8m/s2, what will be the pressure exerted at a depth of 3m in a pond that place?
5. What is the meaning of specific heat capacity of mercury is 140J/kgoc? Write any two differences between heat and temperature. In what temperature water has the highest density?
