A&PI Assignment 6 Integumentary System

What’s the correct answer please?

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. Suppose that each nanocontainer could contain pure oxygen pressurized to a density of 85 g/L. How many grams of oxygen could be contained by each nanocontainer?

The processing of raw coal involves “washing,” in which coal ash (nonorganic, incombustible material) is removed. The article “Quantifying Sampling Precision for Coal Ash Using Gy’s Discrete Model of the Fundamental Error” (Journal of Coal Quality, 1989:33–39) provides data relating the percentage of ash to the volume of a coal particle. The average percentage of ash for six volumes of coal particles was measured. The data are as follows: Volume (cm3) 0.01 0.06 0.58 2.24 15.55 276.02 Percent ash 3.32 4.05 5.69 7.06 8.17 9.36     Using the most appropriate model, predict the percent ash for particles with a volume of 48 cm3. Round answer to three decimal places.   * the answer i got was of 6.260 was wrong

Hello. Can you please help answer the question shown in the photo? It is a 3-part question which I have attempted many times. I was able to calculate the correct answer for part 2, but part 1 and part 3 still says I am incorrect. Please show how to properly solve the problem. The topic is heat transfer. Thank you.

How to get the answer 371lbs. I need the correct explanation within 30-45 Minutes.

A total hip replacement consisting of a 28 mm diameter Co-Cr femoral head articulating against a UHMWPE cup functions in a patient for 5 years before it is removed during revision arthroplasty. You perform a detailed analysis of the explanted cup. The articular surface of the explanted UHMWPE cup shows a change in geometry such that the cup is 0.75 mm deeper (see photo). Radiograph of THR at the time of surgery Assumptions: 28 mm Patient weighs 70kg with an average load of a gate cycle of 2.5BW Neglect creep for all questions Assume 1 million steps per year ANSWER COLUMN THR at day 1 QUESTIONS 0.75 mm THR at 5 years Total angular motion per gait stride (hip flexion-extension-flexion OR heel strike to heel strike) is 80 degrees Hint: Recall details of UHMWPE materials and applications in THR from Lecture 9 Notes. Q1A: Calculate the annual volume of UHMWPE wear debris. UHMWPE after 5 years showing progression of worn region (dark grey)

4 ) Every temperature measuring instrument makes use of specific physical property in order to measure temperature objectively . Which physical properties are used in thermocouple , PT sensors and mercury - in - glass thermometer ? Briefly describe each of this methods.

After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). How many years would it take to melt the iceberg solely by heat from the sun if the ice absorbs a mean of 98 J/m2 -s, 12.5 hrs per day? Note: the exposed area for heating is 250 km x 50 km and the density is 920 kg/m3 .   This is my solution.

P-4 Please I need help with this question needed very clearly and step by step explanation and needed with clear handwriting please, will be really appreciated for your help

A bolt is used to fasten together two copper plates for a cryogenic application. Which material would be the optimal choice for the bolt to prevent the loosening of the parts when introduced to the cold? brass, copper, or mild steel.Justify with quantitative analysis.Provide Solution and short reflection of 1-2 sentences.

Im not sure how ro go about this, can you help me figure out these answers or how to get these answers?

Material properties of a structure cannot be affected by O Colour O manufacturing processes O composition of the material O dimension of the material

Answer the folowing with True or False. Density of a foam material depends on the wall thickness and size of its foam cells.   (     ) BCC structure is more densely packed than the FCC structure. (    ) The anion – cation size ratio has an important influence in determining the crystal structure of ionic solids. (     ) CFRP and GFRP are examples of hybrid materials. ( ) The density of a material is determined exclusively by its atomic weight. ( ) Body diagonal in BCC structure has Miller indices of [111]. ( ) The relationship s = Ee is known the Ohms law. (     ) A closed packed triangular plane in FCC crystal has Miller indices of (111). ( )
