What can longitudinal waves not travel through? Longitudinal waves are like mechanical waves which need the medium to propagate. These waves cannot travel through a vacuum. That is, there is absolutely in a vacuum. If there are no substances, then there are no particles for the sound waves to vibrate, which means the sound waves […]
Which angle of light will heat the wood the most?
Which angle of light will heat the wood the most? 90° angle Why can you see objects placed under a heat lamp which emits infrared radiation? Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can […]

What percentage of drug research is funded by the government?
What percentage of drug research is funded by the government? For the first time in the post–World War II era, the federal government no longer funds a majority of the basic research carried out in the United States. Data from ongoing surveys by the National Science Foundation (NSF) show that federal agencies provided only 44% […]
What do you mean by hydraulic?
What do you mean by hydraulic? Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Where are hydraulic […]
What are 3 products of the light-dependent reactions?
What are 3 products of the light-dependent reactions? The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years. What is importance of light? It seems […]
Is parsec is a unit of Time?
Is parsec is a unit of Time? Unfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to […]
Why do plants look green in color 10?
Why do plants look green in color 10? Answer: The leaves of plants contain green pigments called chlorophyll which is necessary for photosynthesis. Plants reflect green light of sunlight, so they look green. Why are some plants not green in Colour? When leaves contain high concentration of anthocyanin pigments, the leaves appear red or purple […]
What is the significance of reference point for measuring distance?
What is the significance of reference point for measuring distance? A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a […]
