A typical adult human lung contains about 300 million tiny cavities called alveoli. Assume that the alveoli are spherical‚ and that the volume of a typical human lung is about 2 liters‚ estimate the average diameter of a single alveolus. 3. Two vectors have length and What are the maximum and minimum magnitudes of their vector sum? 4. is a vector

Jennifer Ingrum 02/01/11 The Central Nervous System or (CNS) is located in the center portion of the body as its name implies. The (CNS) is made up of the brain and the spinal cord. Our brain is in control of many very important body functions and sensations like these for example: sleep‚ muscle movement‚ memory‚ sexual activity‚ emotions‚ hunger and thirst. Our spinal cord extends several types of nerve fibers from the brain acts like a switching and relay terminal for the peripheral nervous

Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies‚ but instead it can utilize elements of both‚ often within the same study. The term descriptive research refers to the type of research question‚ design‚ and data analysis that will be applied to a given topic. Descriptive statistics tell what is‚ while inferential statistics try to determine cause and effect. Three main purposes of research are to describe‚ explain‚ and validate

of our day-to-day living. My passion lies in Mechanical Engineering‚ specifically in the field of Thermal & Fluid Sciences. Though Mechanical Engineering was an easy choice for me‚ I was still exploring various core concepts ranging from kinematics to material sciences in my first year of study. When I started watching videos such as a man walking on fluid (Shear Thickening Fluid)‚ fluid sticking to a surface (Coanda effect)‚ and cars being lifted by a small pressure from hand (Pascal’s law)‚ Thermodynamics

Engineering Materials Week 4 7.2 Consider two edge dislocations of opposite sign and having slip planes that are separated by several atomic distances. Briefly describe the defect that results when these two dislocations become aligned with each other. When the two edge dislocations become aligned‚ a planar region of vacancies will exist between the dislocations. 7.12 Consider a metal single crystal oriented such that normal to the slip plane and the slip direction are at angles 60 and 35 with the
