Why is the corona hotter? Nanojets are thought to be initiated by a process called ‘magnetic reconnection’, where twisted magnetic fields explosively realign. One such reconnection can set off another, resulting in an avalanche of nanojets in the Sun’s corona, which is then thought to generate enough energy to heat the corona. What triggers lightning? […]
Why does aluminum foil block WiFi signals?
Why does aluminum foil block WiFi signals? If you’ve ever thought of resorting to aluminum foil to redirect your home’s poor WiFi signal, it turns out you’re not actually that far off the mark. The foil, an electrical conductor, creates a barrier called a Faraday Cage around the phone, blocking the radio signals on which […]
What are 5 ways rocks can be broken down?
What are 5 ways rocks can be broken down? Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits […]
Is the Large Hadron Collider dangerous?
Is the Large Hadron Collider dangerous? No. Although powerful for an accelerator, the energy reached in the Large Hadron Collider (LHC) is modest by nature’s standards. What would happen if the Hadron Collider exploded? Given the amount of energy that Nature has stored in the matter of your body, your detonation would change the course […]
What did Japan want in WWII?
What did Japan want in WWII? Faced with severe shortages of oil and other natural resources and driven by the ambition to displace the United States as the dominant Pacific power, Japan decided to attack the United States and British forces in Asia and seize the resources of Southeast Asia. Why did Germany declare war […]
What are the three types of adaptations?
What are the three types of adaptations? There are three different types of adaptations: Behavioural – responses made by an organism that help it to survive/reproduce. Physiological – a body process that helps an organism to survive/reproduce. Structural – a feature of an organism’s body that helps it to survive/reproduce. How does cactus and camel […]
What is the SI unit of respectability?
What is the SI unit of respectability? Magnetic susceptibility indicates the degree of magnetization of a material in response to an applied magnetic field. It is given as: χ=HM. Since both numerator and denominator have units A/m, susceptibility itself is a dimensionless quantity. Why magnetic susceptibility has no unit? Magnetic susceptibility( χ ) is the […]
When should states be capitalized?
When should states be capitalized? You capitalize “state” only when it follows the name of the state, as in “New York State is also called the Empire State,” or when it’s part of a traditional name for a state, like “Empire State” or “Lone Star State.” When it precedes the name of the state, don’t […]
What is the formula for calculating thickness?
What is the formula for calculating thickness? We obtain the thickness of the solid by dividing its volume by its length and its width; that is, we divide 24 cm3 by 4 cm and 3 cm. In this example, the thickness of the solid is 2 cm. Example Exercise 3.10 further illustrates finding the thickness […]
How are elements heavier than beryllium formed?
How are elements heavier than beryllium formed? Elements heavier than beryllium are formed through stellar nucleosynthesis. Stellar nucleosynthesis is the process by which elements are formed within stars. The abundances of these elements change as the stars evolve. What is the heavy element? A heavy element is an element with an atomic number greater than […]
