Why am I all of a sudden getting a lot of Facebook friend requests 2020? The influx of friend requests for verified users is “likely due to recent search changes” on the platform, Facebook says, which were intended to more prominently surface search results for verified accounts over unverified ones. How can I add more […]
What are two types of ions?
What are two types of ions? There are specialized types of ions. Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule. What […]
Why is the storm surge so dangerous?
Why is the storm surge so dangerous? The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Most casualties during tropical cyclones occur as the result of storm surges and surges are a major source of damage to infrastructure and property during storms. How […]
What theory do scientists use to explain the moving continents?
What theory do scientists use to explain the moving continents? Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents. What […]
What are the 5 types of hazards?
What are the 5 types of hazards? Understand and know the Occupational Safety and Health Administration’s (OSHA) five types of workplace hazards and take steps to mitigate employee risk. Safety. Safety hazards encompass any type of substance, condition or object that can injure workers. Chemical. Biological. Physical. Ergonomic. What should you not do in a […]
What is another name for wave velocity?
What is another name for wave velocity? : the velocity of a wave motion as determined by the product of the wavelength and frequency. — called also wave velocity. What is the difference between velocity and frequency? Frequency is a fundamental characteristic of a wave. It is the measure of the number of waves passing […]
What is the importance of Glossopteris?
What is the importance of Glossopteris? They literally reveal how the world we recognise today took shape. Glossopteris was easy to recognise because of its distinctive leaves; the name means “tongue-fern” in Greek, because of its shape. Fossil evidence suggests that the plants probably grew in diverse habitats and came in different forms. What does […]
Are all insulators dielectric?
Are all insulators dielectric? In dielectric materials, the electrons are bound to the nucleus and have limited movement. Thus a dielectric can be defined as an insulator that can be polarized. Thus all dielectrics are insulators, but all insulators are not dielectrics. A dielectric can thus store charge. What does dielectric mean? Dielectric, insulating material […]
Did the electron move into a region of higher potential or lower potential?
Did the electron move into a region of higher potential or lower potential? Because the electron is a negative charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. Because the electron is a positive charge and it accelerates as it […]
Can an object have infinite mass?
Can an object have infinite mass? Advertisement. So when we think of mass as energy, we can begin to understand why an object will increase its ‘mass’ as it speeds up. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well. Does Goku have […]
