Are Heavier arrows more accurate? All factors remaining equal, heavy arrows always are more reliable, more durable, than lighter. More material, with additional layers of carbon material, equal more strength when subjected to abuse such as bone impacts or when shot into rocky ground or bounced off trees following misses. What happens if arrow spine […]
What is the main function of the jejunum and ileum?
What is the main function of the jejunum and ileum? The primary function of the jejunum is to absorb sugars, amino acids, and fatty acids. Both the jejunum and ileum are peritoneal. The ileum absorbs any remaining nutrients that did not get absorbed by the duodenum or jejunum, in particular vitamin B12, as well as […]

Why is the surface perfection of glass fibers so important?
Why is the surface perfection of glass fibers so important? The surface perfection of glass fibers is important because surface flaws or cracks will act as points of stress concentration, which will dramatically reduce the tensile strength of the material. Care must be taken not to rub or abrade the surface after the fibers are […]
When a cannonball is fired from a cannon?
When a cannonball is fired from a cannon? This is called the principle of conservation of momentum . Momentum is conserved in collisions and explosions . Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon […]
How can you tell which star cluster is older?
How can you tell which star cluster is older? By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of […]
How did alchemists contribute to science?
How did alchemists contribute to science? Through the span of several millennia, alchemists “were learning fundamental principles of chemistry: breaking down ores, dissolving metals with acids, and precipitating metals out of solution [8].” This laid the foundations of basic scientific experimentation with modern alchemists such as Boyle emphasizing the … What were some contributions of […]
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet?
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet? Metamorphic rocks form when high temperature and pressure alter existing igneous and sedimentary rocks. Metamorphic rocks can also be formed from other metamorphic rocks. Rock changes in Metamorphic Rocks. Rock changes into metamorphic form when it experiences intense […]
Why was the plum pudding model wrong?
Why was the plum pudding model wrong? He argued that the plum pudding model was incorrect. The symmetrical distribution of charge would allow all the α particles to pass through with no deflection. Rutherford proposed that the atom is mostly empty space. The atom now consisted of a positive nucleus with negative electrons in circular […]
Which fruit is good for metabolism?
Which fruit is good for metabolism? Watermelon, cantaloupe, honeydew—these are naturally good for metabolism. Watermelon may even help with weight loss because it contains the amino acid arginine, which was found in a study of obese mice to reduce body fat gains by 64 percent. How do I know what my metabolism is? A metabolic […]
