What is silicon commonly used for? Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones. What […]
What is the most important rule of solving equations?
What is the most important rule of solving equations? The most important rule of solving equations in algebra is that anything done to one side of an equation must be done to the other. How do you simplify equations? Here are the basic steps to follow to simplify an algebraic expression: remove parentheses by multiplying […]
Is critical value p-value?
Is critical value p-value? As we know critical value is a point beyond which we reject the null hypothesis. P-value on the other hand is defined as the probability to the right of respective statistic (Z, T or chi). We can use this p-value to reject the hypothesis at 5% significance level since 0.047 < […]
Can N and C be joined by a covalent bond?
Which digit is the most uncertain?
Which digit is the most uncertain? In example (1) the digits 3, 5, 8, and 6 are called “certain” digits, because the uncertainty is too small to affect their value. The 9 and the 7 are completely uncertain. How many uncertain digits are there in a measurement? Determining Significant Figures. The significant figures in a […]
What is the new charge on each sphere?
What are the three types of antennas?
What are the three types of antennas? There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional. – Omni-directional antennas propagate in all directions. – Semi-directional antennas propagate in a constricted fashion, defined by a specific angle. What happens if you transmit without an antenna? The electrical issue is that […]
What are the 5 major types of infectious agents?
What are the 5 major types of infectious agents? There are five major types of infectious agents: bacteria, viruses, fungi, protozoa, and helminths. In addition, a new class of infectious agents, the prions, has recently been recognized. What are the 4 types of pathogenic bacteria? Pathogen types. There are different types of pathogens, but we’re […]
What skills do I need to be a paleontologist?
What skills do I need to be a paleontologist? Aspiring paleontologists should have extensive knowledge of biology and geology. A double-major with full training in both is the best educational option. Chemistry, physics, calculus, statistics, and computer science are also very important. What is the salary of a palaeontologist? Initially a paleontologist can expect a […]
What is the general pattern of circulation in the mantle?
What is the general pattern of circulation in the mantle? Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet’s surface. The Earth’s surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. Does […]
