Monochromatic light passes through two slits separated by distance of 0.03 mm. Calculate the wavelength of the light if the angle from the centre fringe to the third maximum is 3°.

Find the volume of the ellipsoid x^2+y^2+5z^2=36.

Astudent pushes a 60-n block across the floor for a distance of 10 m. how much work was done to move the block

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
