Your duty is to construct the above circuit and change Potentiometer resistance until you see 1v 2v……12v at the output voltage which is showing above and at each output voltage measure the resistance and current. Fill the table above and write at least 10-page report. Your input voltage is 12 volts which is constant. Do not change input voltage.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
