What constellations are visible in both hemispheres? Constellations such as Orion may be seen in both hemispheres, depending on your distance from the equator and the time of year. If you can’t see the entire constellation, it’s likely too close to the horizon line and are too far north or south for complete viewing. Are […]

What are the extreme conditions of space? Extreme conditions in the ISS space environment include exposure to extreme heat and cold cycling, ultra-vacuum, atomic oxygen, and high energy radiation. What organisms can live in extreme conditions? Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such […]

What is the 2nd harmonic also referred to? Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic. Which generators have the lowest THD rating? The A-iPower […]

What is a formula of stress? The stress equation is: σ = F/A. F denotes the force acting on a body and A denotes the area. Units of stress are the same as units of pressure – Pascals (symbol: Pa) or Newtons per squared meter. Positive stress means that the object is in tension – […]

What causes a vortex in water? Vortices often form as a result of a difference in fluid speed – like when fast wind moves over slow wind. Because a vortex wants to keep its angular momentum, it keeps spinning as it moves through the water, and only loses a little bit of energy through friction […]

What sound intensity is defined as the level of pain? The level of pain is about 120 dB at all frequencies. The change in physical pressures from threshold of hearing to threshold of pain is twice as great at 2000 Hz (120 dB) as it is at 50 Hz (60 dB). How do you describe […]

Why is space important? Space also provides earth with valuable metals, rare objects and precious materials that can be used for medical research. Space is playing a valuable role in saving lives. If NASA stopped exploring our universe, we would not know important facts about space and our solar system. What is a fact about […]

How do I catch up with my studies? How to Catch Up On Studying When You’ve Fallen Behind Don’t Stay Up All Night. If you’ve fallen behind on your studies, you might be tempted to stay up all night to catch up on studying. Structure Your Time. Falling behind is a good sign that your […]

How do you calculate area with pressure and force? Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. How is area related […]

What is the shape of gef2? trigonal planar What is Vsepr formula? The “AXE method” of electron counting is commonly used when applying the VSEPR theory. The electron pairs around a central atom are represented by a formula AXnEm, where A represents the central atom and always has an implied subscript one. Each E represents […]
