Are eggs bad if they float in boiling water? If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy. However, an egg […]

What is a balanced force in basketball? One balanced force in basketball is standing and shooting a freethrow,because you aren’t moving and no outside force is acting on you. But, an unbalanced force is running down the court and jump-stopping, because your momentum is trying to keep moving forward, but you are trying to stop. […]

What are the 8 steps in scientific method? That procedure is commonly called the scientific method and consists of the following eight steps: observation, asking a question, gathering information, forming a hypothesis, testing the hypothesis, making conclusions, reporting, and evaluating. How do you design an experiment to test a hypothesis? Experimental design means creating a […]

Can we still recover lost Biodiversities? Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area. How does an ecosystem be able to recover from any disturbances? The major mechanisms of recovery in such ecosystems are primary and secondary succession. […]

Can you drink bottled water left in hot car? Some researchers who study plastics recommend against drinking water from plastic bottles that have been sitting in hot places for a long time — such as a car sizzling in the sun — concerned that the heat could help chemicals from the plastic leach into the […]

Do inductors go bad? Inductor Failures Inductors often fail open due to corrosion or bad internal solder joints or the inductors fail shorted due to electrical overstress, bad magnet wire insulation, or potting issues. Some images of common inductor failures are shown below. How do you know if an inductor is bad? The inductor should […]

Can dog whistles damage human ears? Some sounds (such as gunfire or standing next to a helicopter) are so loud (120-160 dB), that any brief exposure to them without wearing earmuffs or earplugs can damage hearing. (This means that the dog whistles are at a very high frequency but that they do not move the […]

What is CP CV called? The Cp/Cv ratio is also called the heat capacity ratio. (i.e.) Heat Capacity ratio = Cp/Cv = Heat capacity at constant pressure/ Heat capacity at constant volume. How do you calculate CP in thermodynamics? cp = cv + R The specific heat constants for constant pressure and constant volume processes […]

Can an electric field be infinite? 3 Answers. So there is no infinity. In two dimensions (or in one), the electric field falls off only like 1r so the potential energy is infinite, and objects thrown apart get infinite speed in the analogous two-dimensional situation. Does electric field increase with distance? Electric field strength is […]

What are the types of GPS? Types of GPS Tracking Devices Personal or Wearable GPS Trackers. This type is often the size of a wristwatch and is used by hikers or hunters in case of an emergency. Vehicles and Equipment. These are slightly larger and are typically used for boats, trailers, cars, or semi-trucks. Plug […]
