What part of the brain triggers the release of adrenaline? After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream. When researchers create They are […]
How can I make my PowerPoint presentation attractive and easy to understand the content?
How can I make my PowerPoint presentation attractive and easy to understand the content? Design and Graphical Images Use design templates. Standardize position, colors, and styles. Include only necessary information. Limit the information to essentials. Content should be self-evident. Use colors that contrast and compliment. Too may slides can lose your audience. Keep the background […]

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 […]
What is difference between atom and element with example?
What is difference between atom and element with example? A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms […]
Why does a piece of tile or stone feel colder than a piece of wood even though both are at same temperature?

What is a density graph?
What is a density graph? Density plots are used to observe the distribution of a variable in a dataset. It plots the graph on a continuous interval or time-period. This is also known as Kernel density plot. Density plots are a variation of Histograms. The peaks of a Density Plot help display where values are […]
Is there an opposite force to gravity?
Is there an opposite force to gravity? Correct answer: In equation form, that means . Use Newton’s second law ( ) to solve for the gravitational force, using acceleration due to gravity as your . As normal force is the opposite of the gravitational force, we can see that . Can you oppose gravity? Yes, […]
How do we demagnetize?
How do we demagnetize? Demagnetization randomizes the orientation of magnetic dipoles. Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal. Demagnetization occurs naturally over time. Can a permanent magnet be Demagnetised? To demagnetise a permanent magnet place it inside a solenoid, pointing East-West, through […]
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 […]
