How do you get ideal gas equation from the gas laws?

Intext Question. Take two convex lenses of different sizes. Collect sunlight on a paper using one of the lenses. The paper will start burning after a while. Note the time required for the paper to start burning. Repeat the process for the second lens. Is the time required the same in both cases? What can you tell from this?

Two simple pendulum A and B of lengths 1.69m and 1.44m start swinging at the time from a location where acceleration due to gravity is 10ms^(-1) . Answer the following question. After how much time, the two pendulums will be in phase again ?

In a young's double slit experiment, the difference in optical path length between the rays starting from the slits S_1 and S_2 and reaching a point A, on the screen in 0.0075mm and reaching another point B on the screen, on the other side of the central fringes is 0.0015 mm. How many bright and dark fringes are observed between A and B if the wavelength of light used is 6000 A^@
