Coherent monochromatic light of wavelength λ passes through a narrow slit of width a, and a diffraction pattern is observed on a screen that is a distance x from the slit. on the screen, the width w of the central diffraction maximum is twice the distance x.

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l
