Can you cook chicken just by slapping it?
Can you cook chicken just by slapping it? Yes, someone just proved you can cook a meat simply by slapping it numerous times. According to his quirky experiment, after hitting the chicken 135,000 times, in a time span of over six hours, it was finally cooked. What is the hardest slap shot? Boston Bruins captain […]
Why can iron form fe3+ and fe2+?
Why can iron form fe3+ and fe2+? It’s essentially about isolated atoms. Fe+2 and Fe+3 are ionization states of iron in molecules or solids. The ultimate reason why both kinds of ions are stable is that 3 electrons are weakly enough held to each Fe atom that they can be pulled away by strong electronegative […]
What causes this disk to form and flatten?
What causes this disk to form and flatten? It is the angular momentum, which results from rotation, that leads to the eventual disk shape. The disk remains in orbit, and it flattens because of angular momentum. Eventually this disk will give rise to planets, asteroids, and planetesimals. What does a nebula look like? Most nebulae […]
Which formula can be used to find the tangential speed?
Which formula can be used to find the tangential speed? Divide the circumference by the amount of time it takes to complete one rotation to find the tangential speed. For example, if it takes 12 seconds to complete one rotation, divide 18.84 by 12 to find the tangential velocity equals 1.57 feet per second. How […]
What is the basic principle of operant conditioning?
What is the basic principle of operant conditioning? Behavior modification is a set of therapies / techniques based on operant conditioning (Skinner, 1938, 1953). The main principle comprises changing environmental events that are related to a person’s behavior. For example, the reinforcement of desired behaviors and ignoring or punishing undesired ones. What are some examples […]
What is a load sensing valve?
What is a load sensing valve? The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle. What does load sensing mean? Load-sensing describes a type of variable pump control used in open circuits. It is also termed this because […]
Do Electrons like to exist in pairs?
Do Electrons like to exist in pairs? Although electrons repel each other, they can “pair,” which really means they share the same energy level. If this repulsion is less than the attraction that both electrons feel for the protons in a nearby atom, however, they will pair and will be more stable in doing so. […]
Where do fish go during a hurricane?
Where do fish go during a hurricane? Slow-moving fish and turtles and shellfish beds are often decimated by the rough undercurrents and rapid changes in water temperature and salinity wrought by a hurricane. Sharks, whales, and other large animals swiftly move to calmer waters, however, and, generally speaking, are not overly affected by hurricanes. Can […]
What type of rock is most likely dominant at mid ocean ridges?
What type of rock is most likely dominant at mid ocean ridges? basalt What is crest of Mid Oceanic Ridge? A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading determines the morphology of […]
