Is Chernobyl still radioactive in 2019?
Is Chernobyl still radioactive in 2019? The ruins of the Chernobyl reactor, now contained under a metal shell, are still highly radioactive and will likely remain so for up to 20,000 years. Why did Valery alekseyevich legasov kill himself? He was buried at the Novodevichy Cemetery in Moscow. While not Legasov’s first suicide attempt, David […]
Is liquid cooling better than fans?
Is liquid cooling better than fans? According to Mark Gallina, liquid cooling more “efficiently distributes heat over more convection surface area (radiator) than pure conduction, allowing for reduced fan speeds (better acoustics) or higher total power.” In other words, it’s more efficient, and often quieter. Is liquid cooling hard to maintain? Liquid cooled systems require […]

Permanent , Temporary , Chemical & Physical Changes Examples of temporary change are : wet sand can change into dry sand. Is chemical change permanent or temporary? Chemical Change Permanent in nature. Since the original composition of […]
What is 4 2He called?
What is 4 2He called? 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay. What is the equation for radioactive decay? The law of radioactive decay describes the statistical behavior of a large number of nuclides, rather than individual […]
Is 2Mg O2 2MgO exothermic?
Is 2Mg O2 2MgO exothermic? 2Mg+O2–> 2MgO + Heat. This is an exothermic reaction. Is mg o2 -> 2mgo balanced? Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced. What kind of reaction is mg o2? Oxygen and magnesium combine in a chemical reaction […]
Can Arccos be negative?
Can Arccos be negative? The arccosine of a negative number is a second quadrant angle, cos-1(-) is in quadrant II. The arctangent of a positive number is a first quadrant angle, tan-1(+) is in quadrant I. Is SEC the same as Arccos? Note, sec x is not the same as cos-1x (sometimes written as arccos […]
Why do objects transfer heat?
Why do objects transfer heat? All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. The transfer or flow due to the difference in temperature between the two objects is called heat. How is heat different from temp? Heat […]
What are waves in everyday life examples?
What are waves in everyday life examples? Transverse waves ripples on the surface of water. vibrations in a guitar string. a Mexican wave in a sports stadium. electromagnetic waves – eg light waves, microwaves, radio waves. seismic S-waves. Do phones really fry your brain? Mobile phones release radiofrequency energy, or radio waves, that can be […]
What are the 5 types of mechanical weathering?
What are the 5 types of mechanical weathering? There are five major types of mechanical weathering: thermal expansion, frost weathering, exfoliation, abrasion, and salt crystal growth. What is example of chemical weathering? With chemical weathering of rock, we see a chemical reaction happening between the minerals found in the rock and rainwater. The most common […]
