What Three criteria are used to evaluate a theory? Fawcett’s criteria are significance, internal consistency, parsimony, testability, empirical adequacy, and pragmatic adequacy. Some of those criteria are differentiated for grand theories and middle-range theories but are not differentiated by type of data-qualitative or quantitative-used to develop the theory. What are the basic components of theory? […]

What happens to the period of a pendulum when the mass is doubled? The time period of a pendulum does not depend on the mass of bob. So if the mass of bob doubled, the time period remains the same. What happens to period if mass is doubled? Thus, if the mass is doubled, the […]

Is RX7 faster than RX8? RX7 is alot faster than RX8, my friend has one. Both cars have bad fuel economy and drinks oil. In the RX7 I understand why it has bad mpg and drinks oil, but in the RX8 I really really dont understand why the mpg is so low in a pretty […]

Does changing the eccentricity change the semi major axis? An ellipse has an eccentricity in the range 0 < e < 1, while a circle is the special case e=0. Elliptical orbits with increasing eccentricity from e=0 (a circle) to e=0.95. For a fixed value of the semi-major axis, as the eccentricity increases, both the […]

What are the two classes of matter? Classifying Matter Matter can be classified into several categories. Two broad categories are mixtures and pure substances. A pure substance has a constant composition. All specimens of a pure substance have exactly the same makeup and properties. What group of mixtures can be separated by handpicking? Answer Expert […]

How are primary and secondary windings of a transformer connected? Generally, the primary winding of a transformer is connected to the input voltage supply and converts or transforms the electrical power into a magnetic field. While the job of the secondary winding is to convert this alternating magnetic field into electrical power producing the required […]

What is the oldest rock layer in the Grand Canyon? Remember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds. Even the youngest rock layer, the Kaibab Formation, is 270 million years old, many years older than the canyon itself. Geologists […]

Are the Andes higher than the Rockies? The Andes are the longest mountain range in the world, covering over 4,300 mi (7,000 km) in length! The Rocky Mountains are located in North America. They extend from New Mexico, northward through Canada, and into Alaska, covering roughly 3,000 mi (4,800 km) in length. How cold is […]
