Again, r 0 is replaced by the capillary length a for large rods. karanasan sa pagsulat ng akademikong sulatin gaya ng liham

Apr 28, 2018 · Best answer (c) at a distance l/2 from 0 Explanation: Since the rod is uniform its Center of mass (CoM) will be in the middle i.e. at l/2 distance from the ends. When the rod is vertical the CoM will bel/2 distance vertically above the point O. Since there is no force in the horizontal direction the CoM will be on the point O after it falls down. perpendicular bisector.

May 04, 2021 · Plate/fin heat exchangers have lots of thin metal plates or fins with a large surface area (because that exchanges more heat more quickly); heat exchangers in gas furnaces (gas boilers) work this way. Artwork: A simple example of a plate/fin heat exchanger. This is a cross-flow design with the two fluids flowing past one another at right angles. Focusing a Collimated Laser Beam. As a first example, we look at a common application, the focusing of a laser beam to a small spot. The situation is shown in Figure 1. Here we have a laser beam, with radius y 1 and divergence θ 1 that is focused by a lens of focal length f. From the figure, we have θ2 = y1/f.
