Atypical radius for a raindrop is 2.0mm. modelling the raindrop as a thin double-convex lens with radii of curvature |r| = 2.0mm, compute the focal length of the lens. water has an index of refraction of 4/3. select one of the following: (a) 0 (b) 1mm (c) 2mm (d) 3mm

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

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.
