How many impact tests are there? There are basically two types of impact tests: pendulum and drop weight. Izod, Charpy, and tensile impact are the most common of the pendulum type tests. What is the difference between Charpy impact test and Izod impact test? In the Charpy impact test, the sample lies flat on the […]
What are disadvantages of fertilizers?
What are disadvantages of fertilizers? Fertilizers have the following disadvantages: They are expensive. The ingredients in the fertilizers are toxic to the skin and respiratory system. Excessive use of fertilizers damages the plants and reduces soil fertility. Leaching occurs and the fertilizers reach the rivers causing eutrophication. What is the main disadvantage of using inorganic […]
What is amplitude of signal?
What is amplitude of signal? The amplitude of a variable is the measure of how far, and in what direction, that variable differs from zero. Thus, signal amplitudes can be either positive or negative. The time-domain sequences in Figure 1–3 presented the sample value amplitudes of three different waveforms. Is amplitude directly proportional to time? […]
How quick can evolution happen?
How quick can evolution happen? Across a broad range of species, the research found that for a major change to persist and for changes to accumulate, it took about one million years. How Fast Is human evolution? A study by anthropologists John Hawks, Henry Harpending, Gregory Cochran, and colleagues suggests that human evolution has sped […]
What is the universal system of measure?
What is the universal system of measure? The International System of Units (SI, abbreviated from the French Système international (d’unités)) is the modern form of the metric system. It is the only system of measurement with an official status in nearly every country in the world. What metric unit would you use to measure the […]
What is lateral and longitudinal acceleration?
What is lateral and longitudinal acceleration? The longitudinal acceleration is in g force again similar to the lateral load transfer. The g force value is “Ax”. If you have acceleration in meters per second squared then the below equation can be used to convert it into units of g. If the longitudinal acceleration is due […]
What are 4 things we automatically process?
What are 4 things we automatically process? Some examples of automatic processes include motor skills, implicit biases, procedural tasks, and priming. The tasks that are listed can be done without the need for conscious attention. Implicit biases are snap judgments that people make without being aware that they made them. What three things do we […]
What is diagram example?
What is diagram example? In science the term is used in both ways. For example, Anderson (1997) stated more generally: “diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects’ sketches are all examples of diagrams, whereas photographs and video are not”. Why is a diagram important? […]
Where is the potential energy of the system the greatest?
Where is the potential energy of the system the greatest? Where is the potential energy of the system the greatest? At the highest point of the oscillation. At the new equilibrium position of the oscillation. Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is […]
What are the example of periodic?
What are the example of periodic? The definition of periodic is something that is recurring at regular intervals, or happens from time to time. An example of periodic is a person’s birthday happening once each year. An example of periodic is a person going to their favorite restaurant every once in awhile. What do you […]
