How does flow rate affect heat transfer? On the other hand, an increase in the heat transfer coefficient is observed if the area is maintained constant. Doubling the mass flow rate will result in a 92% increase in the heat transfer coefficient. However, there is a concomitant increase in the pressure drop, proportional to the […]
Why nitrogen-fixing bacteria are important?
Why nitrogen-fixing bacteria are important? Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle. Why can’t plants fix nitrogen? Earth’s atmosphere contains a huge pool […]
What is the best metal to conduct electricity?
What is the best metal to conduct electricity? Silver Is vegetable oil good or bad conductor? Vegetable oil is a poor conductor of electricity. It does not conduct electricity. Vegetable oil are not necessarily “good” conductors of electricity but yes they will conduct electricity. Most things conduct electricity at some level, they may have high […]

What is the resistance between terminals A and B? Hence the resistance across the terminals A and B is 5 ohms. So the correct answer is option […]
What is an example of operant conditioning in everyday life?
What is an example of operant conditioning in everyday life? Positive reinforcement describes the best known examples of operant conditioning: receiving a reward for acting in a certain way. Many people train their pets with positive reinforcement. How is operant conditioning used today? Operant conditioning can also be used to decrease a behavior via the […]
What are some examples of fixed expenses?
What are some examples of fixed expenses? While these fixed costs may change over time, the change is not related to production levels but rather new contractual agreements or schedules. Examples of fixed costs include rental lease payments, salaries, insurance, property taxes, interest expenses, depreciation, and potentially some utilities. Is food a fixed or variable […]
What is mean by nuclei?
What is mean by nuclei? Plural nuclei (nōō′klē-ī′) The positively charged central region of an atom, composed of one or more protons and (for all atoms except hydrogen) one or more neutrons, containing most of the mass of the atom. The number of protons in the nucleus determines the atom’s atomic number and its position […]
What rocks is coarse grained?
What rocks is coarse grained? Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. What are the most common […]
What is ∈ called?
What is one major difference between plasma and gas and why does that difference exist?
What is one major difference between plasma and gas and why does that difference exist? They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the […]
