Which mechanisms of heat transfer will work in a vacuum quizlet? a. Yes, heat transfer by conduction will occur through a vacuum. Which heat transfer process is increased by profuse sweating? Convective heat exchange increases with increasing air speed and increased differences between air and skin temperature. Evaporation of sweat from the skin cools the […]
What enzyme digests proteins?
What enzyme digests proteins? The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes— trypsin, elastase, and chymotrypsin—act on the peptides reducing them to smaller peptides. Where does the digestion […]
How are electric charges created?
How are electric charges created? A. Electrons can be removed from atoms and accumulated to produce a negative charge. Atoms from which electrons have been removed produce positive electric charge. … What is range of electric force? The electric force is operative between charges down to distances of at least 10-16 metre, or approximately one-tenth […]
Why do you set the altimeter?
Why do you set the altimeter? Weather changes that affect temperatures and air pressures cause the complications in understanding and using an altimeter. This is why an aircraft’s actual height above mean sea level is its true altitude while what the altimeter says is the indicated altitude. Before going flying, you have to set the […]
What are 5 ways to conserve energy?
Is the inside of a battery dangerous?
Is the inside of a battery dangerous? Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into. For lead batteries, sulfuric acid is the dangerous residue, which requires a different type of clean-up. What is inside […]
What are derived units give examples?
What are derived units give examples? Answer. Definition: A derived unit is a SI unit ofmeasurement comprised of a combination of the seven base units. Examples: The SI unit of force is the derived unit newton or N. A newton is equal to 1 m. What are derived quantities give examples? Derived quantities are the […]
What is the difference solution and suspension?
What is the difference solution and suspension? 1. Solutions are mixtures that are homogeneous while suspensions are mixtures that are heterogeneous. 2. The particles of a solution are at the ion or molecular level and cannot be seen by the naked eye while the particles of a suspension can be seen by the naked eye. […]
How do plants return water back into the environment?
How do plants return water back into the environment? Plants soak up large amounts of water through their roots. The water then moves up the plant and evaporates from the leaves in a process called transpiration. The process of transpiration, like evaporation, returns water back into the atmosphere. What’s it called when plants lose water […]
