Why does a metal spoon feel colder than a wooden spoon? Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. It is because the metal conducted heat faster that it feels colder than the wood, which conducted […]
Can flattened into thin sheets?
Can flattened into thin sheets? Malleability is a substance’s ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Can be flattened into thin sheets answer? Answer : (a) The property of […]
Which is true to P waves and S waves?
Which is true to P waves and S waves? P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them. P-waves are compression waves that apply a force in the direction […]
Is time a derived unit?
Is time a derived unit? Fundamental units of measurements are kilograms, meters, and seconds—in regards to mass length, and time. These derived units can be expressed in terms of fundamental units, such as acceleration, area, energy, force, power, velocity and volume. Derived quantities will be referred to as time, length, and mass. Is Joule a […]

What happens to proteins dissolved in 100 C water?
What happens to proteins dissolved in 100 C water? Protein breaks down into amino acids, which can be reassembled into new proteins. Are proteins dissolved in water? Proteins are buid up out of amino acids. All amino acids have a similar backbone structure, but differ in their side chains. These side chains have different properties, […]
How many seconds before you turn should you signal?
What are the advantages and disadvantages of primary and secondary data?
What are the advantages and disadvantages of primary and secondary data? Some common advantages of primary data are its authenticity, specific nature, and up to date information while secondary data is very cheap and not time-consuming. Primary data is very reliable because it is usually objective and collected directly from the original source. What are […]
How the nervous system works with the circulatory system?
How the nervous system works with the circulatory system? The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate […]
