How dangerous is the asteroid belt? The danger lies not in the risk of hitting a large object. The number of objects in the asteroid belt increases steeply with decreasing size, but even at micrometer sizes the Pioneer spacecraft were hit only a few times during their passage. That is not to say that asteroids […]
What are the 2 main functions of the skin barrier?
What are the 2 main functions of the skin barrier? The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. What ingredients repair skin barrier? Whether your skin’s barrier is damaged or healthy, it’s […]
What cartilages of the larynx play the most important in sound production?
What cartilages of the larynx play the most important in sound production? The arytenoid cartilages are roughly pyramidal masses of cartilage that sit on top of the posterior side of the cricoid cartilage. These tiny cartilages play a vital role in the production of sound and act as the pivot points for the vocal folds […]
What is 3D triangle called?
What is 3D triangle called? In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. How do you identify 3D shapes? In geometry, a three-dimensional shape can be defined as a solid figure or an object […]
Does UV light break down ozone?
Does UV light break down ozone? UV light will create ozone from atmospheric oxygen at short wavelengths of less than 240 nanometers (nm). UV light will also destroy ozone and break ozone back down into atomic oxygen (O) and diatomic oxygen (O2) at wavelengths from about 200 nm to 315 nm. How do you kill […]
What does neutrino mean?
What does neutrino mean? A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly […]
What is difference between bacteria and archaea?
What is difference between bacteria and archaea? Difference in Cell structure Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester […]
Can I reverse a transformer?
Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]
How do I raise the pH in my pool without alkalinity?
Which item will sound travel faster?
Which item will sound travel faster? Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. Why […]
