Which polynomial is factored completely? We say that a polynomial is factored completely when we can’t factor it any more. Here are some suggestions that you should follow to make sure that you factor completely: Factor all common monomials first. Identify special products such as difference of squares or the square of a binomial. Which […]
What is another name for a decomposition reaction?
What is another name for a decomposition reaction? Decomposition reactions are also known as analysis reactions or chemical breakdowns. The opposite of this type of reaction is a synthesis, in which simpler reactants combine to form a more complex product. How can a displacement reaction be recognized? Recognizing a Single-Displacement Reaction Usually, when two compounds […]
How is communication possible without a physical medium?
How is communication possible without a physical medium? An unguided transmission transmits the electromagnetic waves without using any physical medium. Therefore it is also known as wireless transmission. In unguided media, air is the media through which the electromagnetic energy can flow easily. What is the role of transmission medium in a network? Transmission media […]
Why atoms tend to lose and gain electrons?
Why atoms tend to lose and gain electrons? Most atoms do not have eight electrons in their valence electron shell. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are […]
Why is gravity weaker underwater?
Why is gravity weaker underwater? This is because water exerts a kind of frictional force called “force of buoyancy”. When you throw something into water , the water below the object will push it upwards making the object weigh less. Why is there no gravity under water? There is gravity everywhere. Gravity is just the […]
Is Split Brain bad?
Is Split Brain bad? Disadvantages of Having a Split Brain When the right and left side of the brain are un able to communicate then it can cause an almost split personality and actions performed by either hemisphere can be performed without the other hemisphere being aware of it. What do split brain patients teach […]

Why does white light look blue?
Why does white light look blue? White light is a mixture of all wavelengths in visible spectrum. The blue glass has a property to absorb all colors except blue. Hence only blue is transmitted and thus the light seems to be blue. How do you reverse blue light damage? Try the “20-20-20” rule. Every 20 […]

What is a good insulator?
What is a good insulator? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of […]
