Was Newton an average student?
Was Newton an average student? You see, when Newton first started his studies at The King’s School in Grantham, England, he was, for all intents and purposes a decidedly average student. Now it’s recorded that along with being a fairly average student, Newton was also a very lonely young boy who suffered at the hand […]
Why is the anode positive?
Why is the anode positive? In an electrolytic cell(one used for electrolysis), the anode is positively charged. This is because the electrode connected to the positive terminal of the battery is where the negatively charged ions go to lose electrons, that is, to get oxidized. Why is anode positive and anion negative? The battery pumps […]
What is the medical term for the graphic record of the electrical impulses of the heart?
What is the medical term for the graphic record of the electrical impulses of the heart? ECG/EKG. The graphic record of the electrical current as it progresses through the heart. How is bipolar recording done? Bipolar electrodes are fabricated by hot-pressing the graphite felt sheets onto both sides of the conducting plastic substrates so that […]
What is the importance of standard units?
What is the importance of standard units? We need standard unit for measurement to make our judgement more reliable and accurate. For proper dealing, measurement should be same for everybody. Thus there should be uniformity in measurement. For the sake of uniformity we need a common set of units of measurement, which are called standard […]
What is meant by anodising?
What is meant by anodising? Anodising is an electrolytic process for producing thick oxide coatings, usually on aluminium and its alloys. The oxide layer is typically 5 to 30µm in thickness and is used to give improved surface resistance to wear and corrosion, or as a decorative layer. What is anodising give its application? Anodising […]
What is the most environmentally friendly driveway?
What is the most environmentally friendly driveway? Gravel. Pros: Gravel is a great option for the budget-conscious, especially people with longer driveways, Bean says. Another selling point: “Gravel compacts much better than plain rocks,” creating a more stable surface that sheds water easily, Bean says. Are concrete pavers bad for the environment? Concrete and asphalt […]
What passes through the filtration membrane?
What passes through the filtration membrane? The resulting filtrate is a dilute solution that includes water, electrolytes, wastes, nutrients, and other molecules able to pass through the filtration membrane. The regulation of the rate of filtration is important. What three hormones factors do the kidneys secrete into the blood? The kidney secretes (1) renin, a […]
What gives the measure of inertia?
What gives the measure of inertia? There are two numerical measures of the inertia of a body: its mass, which governs its resistance to the action of a force, and its moment of inertia about a specified axis, which measures its resistance to the action of a torque about the same axis. See Newton’s laws […]
