When the mass is at rest, the spring stretches y0 = 5 cm beyond its natural length lspring = 14 cm. Standard Exercise The Intense Speakers 1) For this system, in the vertical configuration, y0 = 5 cm gives the equilibrium position. False True Submit Hide Solution Standard Exercise The Speeding Car Standard Exercise Heating a Metal Strip Solution: This question asks about the effect of gravity on the equilibrium position of a spring. Remember that the effect of a gravitational force is to stretch the spring an amount Δx = mg/k. This stretch in the spring represents an offset in the natural (horizontal) equilibrium position of the spring. While the question is strangely worded, the answer is true, the change in position y0 = 5 cm represents the new equilibrium position. Standard Exercise Compressing...

...PAGHIHIRAM NG MGA SALITA Walang salitang buhay na gaya ng Filipino ang puro.may mga salitang banyaga na hindi matatagpuan sa salitang Filipino kapag isinasalin. Bukod sa katotohanang ang wika ay nakasanding sa kultura. Sa pangyayaring ito,ang tanging magagawa ay manghiram o kaya ay lumikha ng bagong salita. Dahil hindi lahat ng salita ay maaring bigyan ng salin o matutumbasan. Walang masama sa panghihiram ng salita. hindi naman kailangan pang humingi ng pahintulot sa bansang hihiraman na mga salita ;hindi rin kailangan pang isauli ang salita pagktapos na hiramin hindi rin ito nakakahiya 1.Tuwirang Hiram - hinihiram ng buo ang salitang banyaga at inaangkop ang bigkas at ispeling sa ortograpiyang Filipino. Halimbawa: Barco Barko Antenna Antena Repollo Repolyo Silla Silya Piña Pinya 2. Ganap na hiram - dahil sa praktikalidad hinihiram ng buo ang salitang banyaga nang walang pagbabago sa anyo nito. Noong sinaunang panahon kapag nanghihiram ng salita, ang unang preperens ay Kastila sapagkat konsistent ang ispeling nito (Kastila) tulad ng Filipino. Ngunit ngayon, higit na pinipili ang Ingles.

...Richard Ching Biology 141 Exam 1 Study Questions 1-15 1. What is the difference between an hypothesis and a scientific Theory? Between an hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world, and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. A scientific theory is an explanation for a broad class of phenomena or observations, whereas a hypothesis is a testable statement to explain the workings of a particular scientific theory. In other words, a hypothesis aims to find out how a phenomena occurs. What distinguishes a hypothesis from a prediction is that a prediction is simply a part of a hypothesis, and is an observable or measureable result that must hold true if the hypothesis is correct. A hypothesis is useful to a scientific investigation in the case that it can be tested and have results gathered from experimentation or observation, while hypotheses that cannot be tested and concluded upon are not useful. An example of a useful hypothesis is the question of whether or not cramming increases test performance when compared to consistent studying, and an example of a hypothesis that is not scientifically useful would be the question of whether God truly exists. 2. Two of the greatest unifying ideas in biology (i.e., concepts that account for and are consistent with a very large number of observations) are the Cell Theory, and the Theory...
