How does the jet stream affect the weather where you live? How Do Jet Streams Affect Weather? The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. However, if a weather system is far away from a jet stream, it might stay in one place, […]
Do we need oxidants?
Do we need oxidants? Oxidation can damage vital molecules in our cells, including DNA and proteins, which are responsible for many body processes. Molecules such as DNA are needed for cells to function properly, so if too many are damaged, the cell can malfunction or die. This is why antioxidants are important. Why are oxidants […]

Why is it important to exercise your cardiovascular and cardiorespiratory systems?
Why is it important to exercise your cardiovascular and cardiorespiratory systems? Improving cardiovascular fitness can reduce your risk of developing heart disease by increasing the efficiency of your heart, lungs, and blood vessels. The easier it is to pump blood through your body, the less taxing it is on your heart. How can you improve […]
What exactly is Fourier Transform?
What exactly is Fourier Transform? The term Fourier transform refers to both the frequency domain representation and the mathematical operation that associates the frequency domain representation to a function of space or time. … What are the applications of Fourier transform? The Fourier transform has many applications, in fact any field of physical science that […]
Is radioactive decay bad?
Is radioactive decay bad? Radiation can either kill cells or damage the DNA within them, which damages their ability to reproduce and can eventually lead to cancer. When radiation is present, high energy particles pass through your body. These can collide with atoms in your body and disrupt atomic structure. What is a decay constant […]

What is the effect of HCl on the pH of water?
What is the effect of HCl on the pH of water? A molecule of hydrochloric acid, for example, is composed of a hydrogen atom and a chlorine atom. When these molecules dissolve into water, they separate into a positively charged hydrogen ion and a negatively charged chlorine ion. This leads to an increased concentration of […]
What happens to kinetic energy when velocity decreases?
What happens to kinetic energy when velocity decreases? Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased. Does kinetic energy increase velocity? It turns out that […]
What is the new technology in ESEM?
What is the new technology in ESEM? These problems can now be overcome, thanks to the new environmental scanning electron microscope (ESEM), which permits the imaging of wet systems with no prior specimen preparation. Which gas is used in SEM? However, the first images of wet specimens in an SEM were reported by Lane in […]
