How High a building could fire hoses effectively.........
Screen Shot 2021-01-20 at 2.04.18 PM.png3. How high a building could fire hoses effectively spray from the ground? Fire hose pressures are around 1 MPa. (It is also said that larger fire engine mounted pumps can deliver from 90-300 gallons per minute, and hoses can be as wide as 30 cm diameter What alternative estimate would that info give you?)4. Butterflies and moths use their slender probosci to sip nectar, plant sap, etc. Let the radius be 30 μm, and...

Approximation At some point, scientists are confronted with the recognition that some math problems do not have exact answers. This is very different than the math we learn in high school and college, which typically represents math as a construction that only has exact answers (2 + 2 = 4 and not any other number) What is the expected time of diffusion of biologically important molecules at different scales? There is no exact answer to a question like how long...

Quantitative: Fick’s first law helps us understand the relationship between a molecule’s concentration gradient (the difference in its concentration at two locations) and its flux. This can be super important for the delivery of drugs to help cure human illnesses. As one example, we’ll think about a transdermal patch that provides medicine to the body. Scopolamine patches are used to treat motion sickness. Scopolamine comes from the nightshade family and is similar to acetylcholine. It antagonizes acetylcholine activity, preventing acetylcholine from...

1) [7 marks] A long straight wire hangs vertically through the middle of a metal basketball hoop of radius R = 23.0 cm. The hoop is horizontal. The wire carries a current of I = 1.56 A, moving vertically upward from the ground toward the sky. a) Sketch the magnetic field inside the hoop, as viewed from above it. b) What is the magnitude of the magnetic field at the hoop's location? c) Is there a net magnetic flux through...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
