What is the torsion test? Torsion testing is a type of mechanical testing that evaluates the properties of materials or devices while under stress from angular displacement. What is difference between tension test and torsion test? The Difference Between Tension and Torsion Springs. Lasting longer due to their sturdiness, torsion springs are typically able to […]

Why are the plants always tall when a tall pea plant is crossed with a short pea plant? Answer: When a tall pea plant is crossed with a short pea plant, the resultant progeny is always tall because tall is dominant trait and short is recessive trait. Therefore, dominant trait expresses itself in the progeny. […]

What is the difference between natural gas and LPG? Gas is gas right? Well chemically it is a different gas, natural gas is methane whereas lpg or bottled gas in propane. The difference is subtle and we will discuss it later but the fundamental difference between LPG (liquid propane gas) and natural gas is the […]

Is accuracy or precision more important to scientific measurement? Accuracy is something you can fix in future measurements. Precision is more important in calculations. When using a measured value in a calculation, you can only be as precise as your least precise measurement. Accuracy and precision are both important to good measurements in science. Why […]

When at a point liquid phase decomposes into two different solids on cooling then it is known as? 4. A eutectic reaction is a three-phase reaction, by which, on cooling, a liquid transforms into two solid phases at the same time. What is the name of the reaction when one solid splits into two solids […]

How do I calculate 95% confidence interval? To compute the 95% confidence interval, start by computing the mean and standard error: M = (2 + 3 + 5 + 6 + 9)/5 = 5. σM = = 1.118. Z.95 can be found using the normal distribution calculator and specifying that the shaded area is 0.95 […]

What is a Level 3 heading? Level 3: Usually used (unless you need only one level), flush left, italicized, upper- and lower-case heading on a line of its own without a period at the end. What is a Level 3 heading in APA? There are five levels of heading in APA Style. Level 1 is […]

Why inclined manometer is used in measuring pressure? The advantage of the inclined manometer is that the differential reading scales along the tube can be made large compared to a vertical manometer for a given pressure difference, hence improving the accuracy in reading the scale. What does an inclined manometer measure? Inclined Manometer in Range […]

How do you find the weight density of a cylinder? How do you calculate the weight of a cylinder? Square the radius of the cylinder. Multiply the square radius by pi and the cylinder’s height. Multiply the volume by the density of the cylinder. The result is the cylinder’s weight. How do you find weight […]

What is the role of consumers in determining what is produced in a market economy quizlet? Consumers have the power in the economy because they determine which products are likely produced. If the consumers like a product, it will sell and the producer will be rewarded for his or her efforts. If consumers reject the […]
