**Step-by-Step Solution:** 1. **Understanding the Properties of Ordinary Rubber:** - Ordinary rubber is known for its elastic properties, which allow it to stretch and return to its original shape. Additionally, it is porous, meaning it has tiny holes or pores that are not visible to the naked eye. 2. **Pressure Inside the Rubber Balloon:** - When a balloon made of ordinary rubber is filled with hydrogen gas, the pressure of the gas inside the balloon is typically greater than the atmospheric pressure outside the balloon. This pressure difference is crucial for understanding why the balloon deflates. ...

The radiations emitted by the sun are analyzed and the spectral energy distribution curve is plotted. as shown. The radius of the sun is R , the earth is situated a distance 'd' from the sun. Treat the sun as perfectly black body which radiates power at constant rate fill till its store of hydrogen gets exhausted. (Stefan's constant = sigma , Wien's constant =b , speed of light =c ) Assume the sun produces energy only by nuclear fusion of hydrogen nuclei and the fraction of nuclear mass of hydrogen that can be converted to energy is eta . How long will the sun keep on emittied the energy if the mass of hydrogen at present in Sun's core is m?
