What is the difference between heat transfer by conduction and convection? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. The heat transfer occurs through a heated solid object. What is the difference between conduction and convection name one medium in? hope this helps. […]

How do I test my water table level? The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing […]

How does the 1st and 2nd law of thermodynamics apply to biological systems? Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy […]

How depletion region is formed in pn junction? Movement of electrons to the p-type side exposes positive ion cores in the n-type side while movement of holes to the n-type side exposes negative ion cores in the p-type side, resulting in an electron field at the junction and forming the depletion region. When depletion region […]

What does it mean to find the inverse of a function? An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. […]

What is the term for the angle at which light undergoes total internal reflection? This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. For any angle of incidence greater than the critical angle, light will undergo total internal reflection. Which of […]

How the body gets rid of waste? Body Waste: Urine In your body, the excretory system helps to keep salts and urea from building up to dangerous levels and becoming toxic. The kidneys are two bean-shaped organs that remove these toxins from your blood and produce urine to carry them from the body. Why is […]

What are the 4 types of assessment? A Guide to Types of Assessment: Diagnostic, Formative, Interim, and Summative. What are the examples of assessment tools? Examples of assessment tools Research Paper Rubric. Checklist. Search Report Process Guide. Evaluation of Instruction. Evaluation of Critiques of Scientific Articles. Evaluation of Lab Reports. Grading Guide. Poster Presentation Rubric. […]

Why does glass amplify sound? It happens because glass resonates at frequencies we can hear. The resonant frequency of the glass changes with its thickness. When energy at that frequency meets the glass, it causes the glass to vibrate like a drum head. How do you physically amplify sound? Untitled Document. Sounds can be made […]

What is difference between PCT and DCT? PCT occurs after the Bowman’s capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT. The main difference between PCT and DCT is that PCT is the function of each part in the nephron. Which is […]
