What is the source of energy for regenerating ATP from ADP? Energy derived from glucose catabolism is used to convert ADP into ATP. When ATP is used in a reaction, the third phosphate is temporarily attached to a substrate in a process called phosphorylation. What happens when ADP is converted to ATP? When one phosphate […]
How far does the tip of the minute hand of a clock move in 20 minutes if the hand is 5 inches long?
Can airbags kill you?
Can airbags kill you? Not only can the airbag can seriously injure you, it can kill you. Second and third generation airbags, even though, they have been de-powered from the mid 1990’s, still deploy outward at 300 mph. A deploying airbag has the explosive equivalent of 20 shotgun shells. This can cause neck fractures and […]
What are the three types of accumulators?
What are the three types of accumulators? Depending on separating elements, we can distinguish three types of hydraulic accumulators: bladder accumulators, diaphragm accumulators, and piston accumulators. What is the purpose of accumulator? Accumulator is a pressure vessel for storing hydraulic pressure in it utilizing compressible and decompressible nature of nitrogen gas. So, it can be […]
How does friction affect total mechanical energy?
How does friction affect total mechanical energy? Mechanical energy is reduced due to friction and converted to heat. This is the reason why there is an increase in temperature in objects that move against each other. The role of friction in a closed system is to convert a part of the total energy to heat. […]
Which is a controllable risk factor?
Which is a controllable risk factor? The “controllable” risk factors are: Smoking. High blood pressure. High blood cholesterol. What are 6 health risk behaviors? 23 These six prior- ity health-risk behaviors are: alcohol and other drug use, behaviors that contribute to unintentional injuries and violence (including suicide), tobacco use, unhealthy dietary behaviors, physical inactivity and […]
What process occurs in stellar explosion?
What process occurs in stellar explosion? Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. The term supernova nucleosynthesis is used to describe the creation of elements during the explosion of a massive star or white dwarf. What is the difference between the two types of supernovae? A type […]
What does a plastic stopper reduce?
What does a plastic stopper reduce? The vacuum prevents conduction. The tight stopper prevents air from entering or leaving the flask, so convection isn’t possible either. The sealed stopper stops heat getting in by convection; the vacuum stops conduction, and the metal lining between the outer case and the inner chamber stops heat radiating in […]
What are the two main types of steam turbines?
What are the two main types of steam turbines? Two types of steam turbines must be considered, condensing and noncondensing. What is the principle of steam turbine? In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into […]
What happens to inductor when switch is closed?
What happens to inductor when switch is closed? When the switch is first closed, the current through the inductor is zero, because it cannot change instantaneously. This means that the inductor acts like an open circuit, so all the voltage is across the inductor. The changing magnetic field creates a back emf which acts to […]
