Can concave lens produce real image? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object. What are the properties of lenses? […]

How do you do IV push medications? Scrub the end cap on your IV line for 15 seconds with a fresh alcohol pad and let it air dry. Twist the syringe of heparin or citrate into the end of your IV line. “Pulse flush” your IV line with the syringe of heparin or citrate. Before […]

When both quantitative and qualitative methods are beneficial? A combination of qualitative and quantitative research is typically best for most design projects if budget allows. By using both methods you can achieve a deeper level of insight through the exploratory nature of the research in addition to statistical evidence to support your design decisions. What […]

What are the examples of physical geography? Physical geography also includes the processes, such as erosion, landslides, earthquakes, and volcanoes, that shape and change the landforms around us. Other elements of physical geography include rock types and minerals, a field known as geology. What are the main elements of physical geography? (b). Elements of Geography […]

Do I have to memorize kinematic equations for MCAT? Kinematic equations are the foundation to mastering MCAT physics. Yes you have to ‘memorize’ and know the standard formulas, but it goes deeper than that. You have to understand the units, when to use which equation, and be VERY comfortable applying these concepts to the more […]

How is temperature determined? Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Does reheating meat kill bacteria? Proper […]

Did Einstein say we Cannot solve our problems with the same thinking we used to create them? The supposed Einstein quote from Skeptic reads “the world we have made as a result of the level of thinking we have done thus far creates problems that we cannot solve at the level of thinking at which […]

What happens if you put a pencil in a glass of water? As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes medium and subsequently undergoes refraction. As a result, the image of […]
