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 […]

Which is an example of a slow process of the carbon cycle? Over millennia, the ocean will absorb up to 85 percent of the extra carbon people have put into the atmosphere by burning fossil fuels, but the process is slow because it is tied to the movement of water from the ocean’s surface to […]

What happens if the Senate and House pass different versions of a bill? If the House and Senate pass the same bill then it is sent to the President. If the House and Senate pass different bills they are sent to Conference Committee. Most major legislation goes to a Conference Committee. Why do the House […]

What material keeps things hot the longest? Answer 4: Materials that are good insulators keep liquids hot for a longer time. Examples of good insulators are silicon, various polymers that form gels and foams, and glass. What material keeps coffee hottest? stainless steel Does tea really taste better in bone china? … anyway, despite the […]

Which element in Period 2 has less mass? lithium Is there a shortage of silicon? Global silicon chip shortage hits supply of phones, TVs, cars and Australia’s NBN. Samsung, which is the largest manufacturer of computer chips in the world, as well as one of the biggest users, has said the chip shortage comes amid […]

What are some examples of radiation heat transfer? Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth […]

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 is the parallax of error and how could we avoid it? Parallax error is primarily caused by viewing the object at an oblique angle with respect to the scale, which makes the object appear to be at a different position on the scale. Read the lower part of the curved surface of the liquid […]

What is the point estimate formula? Once you know these values, you can start calculating the point estimate according to the following equations: Maximum Likelihood Estimation: MLE = S / T. Laplace Estimation: Laplace = (S + 1) / (T + 2) Jeffrey Estimation: Jeffrey = (S + 0.5) / (T + 1) What is […]
