Why are reversible processes more efficient? Reversible processes produce the maximum amount of work If a process does work on the surroundings, you get more work out of the process if it is done slowly. This is because less heat is lost to the surroundings. So a reversible process (infinitely slow) does the maximum work. […]
What is the principle of Pascal law?
What is the principle of Pascal law? Pascal’s law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions. What is the definition […]
What happens if we reverse the polarity of the diode?
What happens if we reverse the polarity of the diode? If the polarity is reversed, they conduct current and there may not be any current-limiting resistance in the circuit to prevent them from overload. Now the diode conducts current, and because the current flow in a forward-biased diode increases exponentially with the voltage, it overloads […]
What is structural personal protective clothing designed to do?
What is structural personal protective clothing designed to do? Figure 6.3 NFPA® 1971 regulates the clothing components that comply with the standard. Structural personal protective clothing is designed to cover all portions of your skin when you are reaching, bending, or moving. It is also designed to prevent heat transfer from the fire to your […]
Does the height depends on the distance between the person and the mirror?
Does the height depends on the distance between the person and the mirror? You will see that you only need a mirror length of about 1/2 your height. This is due to the principle of reflection, which states that the angle of incidence equals the angle of reflection. A light ray from your foot strikes […]
When did electrical engineering start?
When did electrical engineering start? September 1882 Was there electricity in the 18th century? Though humans would not fully understand the nature of electricity until the nineteenth century, the properties of electricity were detected much sooner. would generate an electrical charge when rubbed. … How was electricity generated in the 19th century? The electromagnet proved […]
How do you write a good problem statement example?
How do you write a good problem statement example? How to write a problem statement Describe how things should work. Explain the problem and state why it matters. Explain your problem’s financial costs. Back up your claims. Propose a solution. Explain the benefits of your proposed solution(s). Conclude by summarizing the problem and solution. What […]
What is 2 phase locking protocol?
What is 2 phase locking protocol? Two-Phase Locking (2PL) is a concurrency control method which divides the execution phase of a transaction into three parts. It ensures conflict serializable schedules. If read and write operations introduce the first unlock operation in the transaction, then it is said to be Two-Phase Locking Protocol. How can deadlocks […]
What is the difference between filler and electrode in welding?
What is the difference between filler and electrode in welding? An electrode could be either consumable or non-consumable. (i.e) during welding, the metal reqd to fill the gap could be provided by the electrode itself (SMAW , GMAW ,SAW processes). Filler metal: Metallic wire used to fill the gap between the base metals to be […]
