Monochromatic light with a wavelength of 6.4 e -7 meter passes through two narrow slits, producing an interference pattern on a screen 4.0 meters away. the first order bright band lines are 2.0 e -2 meters away from the central bright maxima. what is the distance between the slits?

1.3 e -4 m

8.0 e -6 m

3.2 e -9 m

7.8 e3 m

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

Which of the following are appropriate acceleration units?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
