A wire made from Material Y has a 3 millimeter [mm] diameter and is 1.25 feet [ft] long. A stress is created by applying a force over the circular cross-sectional area of the wire, where the circular area is given by: A = π r2. This stress causes a strain of 0.045 [mmmm]. Determine the force used to stretch the wire, in units of newtons [N].

Industries involved in viscosity measurement [27, 29] continue to use the CGS system ofunits, since centimeters and grams yield convenient numbers for many fl uids. The absoluteviscosity ( μ ) unit is the poise, named after J. L. M. Poiseuille, a French physician who in1840 performed pioneering experiments on water fl ow in pipes; 1 poise =1 g/(cm-s). Thekinematic viscosity ( ν ) unit is the stokes, named after G. G. Stokes, a British physicist whoin 1845 helped develop the basic partial differential equations of fl uid momentum; 1 stokes =1 cm 2 /s. Water at 20 ° C has μ ~~ 0.01 poise and also ν ~~ 0.01 stokes. Express these resultsin ( a ) SI and ( b ) BG units.

Your professor has recruited you to work in her lab to help her win the Nobel Prize. It is critical that your work be as accurate as possible. Rather than using the stated volumes of glassware in the lab, you decide to calibrate each piece. An empty 10-mL volumetric flask weighed 10.263 4 g. When filled to the mark with distilled water at 208C, it weighed 20.214 4 g. What is the true volume of the flask?

Please help me with the following question. You can use the second photo as reference and please put the whole process and solution because I’m having a difficulty with understanding it. Thank you very much. FN=78 MN=104 SN=66
In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?
During a mountain climbing trip it is observed that the water used to cook a meal boils at 93 °C rather than the standard 100 °C at sea level. At what altitude are the climbers preparing their meal? (See Physical Properties of Water (SI Units) and Properties of the U.S. Standard Atmosphere (SI Units) for data needed to solve this problem.) Wiley saids the answer is 2059.7m. I'd appreciate it if somebody would work it out for me

Nanotechnology, the field of building ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the body’s oxygen transporters. Nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person’s bloodstream. If the person needed additional oxygen—due to a heart attack or for the purpose of space travel, for example—these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. Suppose that the nanocontainers were cubic and had an edge length of 25 nanometers. What is the volume of one nanocontainer? (Ignore the thickness of the nanocontainer’s wall.)
