Which of these is the most likely impact of solar prominence? Answer: Loss of electrical power generation. Explanation: This is because some prominences break apart and may then give rise to coronal mass ejections, which will cause far more damages to the electrical power being used on earth. How do prominences affect the earth? As […]

What is cartilage and its types? There are three types of cartilage: hyaline, fibrous, and elastic cartilage. Hyaline cartilage is the most widespread type and resembles glass. In the embryo, bone begins as hyaline cartilage and later ossifies. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis. What […]

Is 2 cans of tuna a day bad? Though tuna is very nutritious, it’s also high in mercury compared to most other fish. Therefore, it should be eaten in moderation — not every day. You can eat skipjack and light canned tuna alongside other low-mercury fish a few times each week, but should limit or […]

Why is negative free energy spontaneous? Spontaneous reactions release free energy, which can be used to do work. A mathematical combination of enthalpy change and entropy change allows the change in free energy to be calculated. A reaction with a negative value for ΔG releases free energy and is thus spontaneous. What causes entropy to […]

What is the best type of graph? Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. What […]

Can a vasectomy grow back? A vasectomy can fail if the doctor misses the vas deferens during the procedure. In rare cases, the tube can regrow. If this does occur, the vas deferens is usually much smaller than it was before. Sometimes, sperm can make their way from one cut end of the vas deferens […]

Which variables are easy to measure? Many variables studied by psychologists are straightforward and simple to measure. These include sex, age, height, weight, and birth order. You can often tell whether someone is male or female just by looking. How do we use measure variables? You can see that one way to look at variables […]

What does the 2 stand for in Li2O? The ionic formula for Lithium Oxide is Li2O . This makes oxygen a O−2 anion. Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two Li+2 cations will balance with one O−2 anions. What is the […]

What is the main function of alveoli? The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body. What destroys the […]

O que significa C32 no disjuntor? C32 A no disjuntor quer realmente dizer que ele desarma em 32 ampéres. C significa que ele possui a mais rápida resposta à essa corrente máxima. Qual disjuntor e sua classe utilizar em residência? Disjuntor Unipolar: É indicado para circuitos com uma única fase. Ex: Circuitos de iluminação e […]
