Consider a double-slit arrangement in which an interference pattern is formed on a screen 80.0 cm away from the slits. Light with a wavelength of 656.3 nm is incident on the slits, which have a separation of 0.180 mm. Calculate the fraction of the maximum intensity a distance y = 0.600 cm away from the central maximum.

What is friction? how does it affect the motion of an object?

Madison lives near the ocean. she’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. if madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:

An air standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes. 1-2 isentropic compression 100 kpa and 22°c to 600 kpa 2-3 v=constant heat addition to 1500 k 3-4 isentropic expansion to 100 kpa 4-1 p=constant heat rejection to initial state (a) show the cycle on p-v and t-s s (b) calculate the net work output per unit mass (409 kj/kg) (c) determine the thermal efficiency (47.9%)
