What causes Oxbow? An oxbow lake forms when a river creates a meander, due to the river’s eroding bank . After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck by sedimentation of silt, cutting off the meander […]

Is Van de Graaff generator a capacitor? A leyden jar is a storage capacitor which can withstand very large voltages. A van de graaf generator is a charge pump which can generate large voltages, but at very small currents. When you connect a van de graaf to a leyden jar, the jar accumulates the energy […]

What are the possible sources of error in titration? Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette. […]

What is inside of a ping pong ball? Celluloid is a thermoplastic made from nitrocellulose and camphor. Sometimes dyes and stabilizers are added. A typical ping pong ball might consist of 70% to 80% nitrocellulose, with up to 30% camphor. Small amounts of dye, ethanol, and stabilizers make the ball colorful, more stable, and less […]

What is a good attack angle? While there are exceptions, this is my basic formula for players in college or pro ball: If the hitter’s peak exit velocity is under 105 mph, their attack angle should be between 5 and 15 degrees. If their peak exit velocity is above 105 mph, it should be between […]

What are the advantages of observation in research? The biggest advantage of observational research has already been noted: it enables businesses to observe potential customers in a natural setting, which can reveal penetrating insights unavailable through other methods such as focus groups and surveys. What are the advantages and disadvantages of a survey? Advantages of […]

What is the minimum ceiling for VFR flight? IFR means a ceiling less than 1,000 feet AGL and/or visibility less than three miles. Low IFR (LIFR) is a sub-category of IFR. VFR means a ceiling greater than 3,000 feet AGL and visibility greater than five miles. What is the minimum VFR? Basic VFR Weather Minimums […]

How do you describe a function? A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range. What are the qualities of a function? […]

What is Ammeter explain with diagram? An ammeter (from ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. What is meant by […]

What is the definition of similarities and differences? Answer. The word similarities means the comparison of 2 or more things that have something in common. The word differences means the comparison of 2 or more things that are different in any way. Hope this helps. How do you write similarities? How to Write a Compare […]
