What measurement represents volume? Volume is the measure of the amount of space occupied by an object. The standard SI unit of volume is defined by the base unit of length (Figure 3). The standard volume is a cubic meter (m3), a cube with an edge length of exactly one meter. Which choice best describes […]
What is the most common rock?
What is the most common rock? Sedimentary rocks Is basalt rock hard? Basalt is a hard, black volcanic rock with less than about 52 weight percent silica (SiO2). Because of basalt’s low silica content, it has a low viscosity (resistance to flow). Therefore, basaltic lava can flow quickly and easily move >20 km from a […]
What is the difference between non science and pseudoscience?
What is the difference between non science and pseudoscience? In short, while not all non-science is pseudoscience, all pseudoscience is definitely non-science. While pseudoscience is the most dangerous subspecies of non-science, philosophical discussions of the problem of demarcation aim to extract those features that make science what it is. Does science have to be falsifiable? […]
Which is not a power function?
Which is not a power function? This is called an exponential function, not a power function. What is a power in math? A power is the product of multiplying a number by itself. Usually, a power is represented with a base number and an exponent. The base number tells what number is being multiplied. How […]
What is dynamic warm up and why use it?
What is dynamic warm up and why use it? In simple terms, a dynamic warm-up is “moving while you stretch” or stretching through a joint’s full range of motion and preparing muscles for more intense exercise to come. A dynamic warm-up promotes blood flow, helps PREVENT INJURY and muscle soreness, as well as helps improve […]
How can protein synthesis be increased?
How can protein synthesis be increased? Ten grams of essential amino acids or twenty-five grams of a complete protein are sufficient to maximally stimulate protein synthesis. Type, timing and amount of protein are all factors in maximizing muscle mass. How do you explain protein synthesis to a child? Protein synthesis is a term that means […]
Which object is not light source?
Which object is not light source? A few examples of artificial light sources include light bulbs, lamp posts and televisions. Without light sources we could not see the world around us, however, not every object we see is a light source. Many objects simply reflect light from a light source, for example tables, trees and […]
Is oil really fossil fuel?
Is oil really fossil fuel? Fossil fuels include coal, petroleum (oil), natural gas, oil shales, bitumens, and tar sands and heavy oils. For modern life, these energy sources rival food and water in importance. Why can’t we get rid of fossil fuels? We understand today that humanity’s use of fossil fuels is severely damaging our […]
Can two electric field lines intersect each other?
Can two electric field lines intersect each other? Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible. Why can’t two field lines intersect each […]
