How do you strengthen a magnet? Place your weak magnet within the magnetic field of a much stronger magnet. Setting it right next to the magnet will produce the best result. The stronger magnet will actually help realign electrons that have spun out of axis since it’s creation. Stroke the weak magnet with your larger, […]
How can a fully dressed person at rest in the middle of a pond on perfectly frictionless ice get to shore?
Why protein is not a genetic material?
Why protein is not a genetic material? For a material to be genetic material, it has to replicate, it must be stable both structurally and chemically stable. Furthermore, it must be able to provide a scope for mutations eventually, key for evolution. Where are proteins made? Ribosomes Are proteins made in cytoplasm? Proteins all begin […]
What are the characteristics of mid-ocean ridges?
What are the characteristics of mid-ocean ridges? Principal characteristics. Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of […]
Which best describes the motion of an object?
Which best describes the motion of an object? You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move. Which formula is used to find an objects acceleration? […]
What happens to the energy when you place a liquid in the freezer?
What happens to the energy when you place a liquid in the freezer? When water freezes it gives up some of the water’s energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released. Energy is being transferred even through […]
What is the recommended amount of physical activity for children Topic test?
What is the recommended amount of physical activity for children Topic test? Kids and teens should get 60 minutes or more of moderate to vigorous physical activity daily. Toddlers and preschool children should play actively several times a day. Toddlers should get at least 60 minutes active play every day and preschoolers should have at […]
How can an object accelerate towards the center without getting closer to the center?
How can an object accelerate towards the center without getting closer to the center? If an object is in uniform circular motion, then it is accelerating towards the center of the circle; yet the object never gets any closer to the center of the circle. It maintains a circular path at a constant radius from […]
What is the SI unit of time?
What is the SI unit of time? second. The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, […]
