Do sound waves ever die? The godfather of radio technology decided that no sound ever dies. It just decays beyond the point that we can detect it with our ears. Any sound was forever recoverable, he believed, with the right device. Does sound travel faster in water or steel? In fact, sound waves travel over […]

Can a car spring kill you?
Can a car spring kill you? Compressing springs is a very dangerous job. The energy that compressed springs pack is tremendous. If your redneck, home-made coil spring compressor were to fail it could literally crack your skull, take your face off and even kill you. Can coil springs be adjusted? Most import passenger vehicles use […]
Is carburetor better than fuel injection?
Is carburetor better than fuel injection? So with a carburetor, the best fuel to air ratio for each cylinder is approximated for the best performance. However, carburetors do last longer than fuel injection systems and are favored in motor sports. The carburetor is currently much less expensive than the electronic fuel injection systems. Which way […]
Is it bad to change from reverse to drive while moving?
Is it bad to change from reverse to drive while moving? It’s never a good idea to shift your vehicle into gear, whether from “Neutral” or “Park”, when the engine is idling fast. Shifting into “Drive” or “Reverse” can cause a sudden, jarring movement on the transmission which increases the stress on the transmission bands […]
What are the conditions under which gases deviate from ideality?
What are the conditions under which gases deviate from ideality? The two condition at which the gases deviate from ideal behaviour are low temperature and high pressure. At high pressure and at low temperature the volume is less, so the volume occupied by the individual molecule can not be neglected compare to the total volume. […]
How do you find the inverse relationship?
How do you find the inverse relationship? When one variable increases the other decreases in proportion so that the product is unchanged. If b is inversely proportional to a, the equation is of the form b = k/a (where k is a constant). y is inversely proportional to x. How can you recognize when two […]
What is the maximum number of electrons that can be accommodated in L 3?
What four processes make up the simple ideal Brayton cycle?
What four processes make up the simple ideal Brayton cycle? 9-24C The four processes that make up the Otto cycle are (1) isentropic compression, (2) v = constant heat addition, (3) isentropic expansion, and (4) v = constant heat rejection. How does the Brayton cycle work? According to the principle of the Brayton cycle, air […]
Does air travel from hot to cold?
Does air travel from hot to cold? Hot air does not move toward cold as. The temperature of air alone does not determine airflow characteristics. You should also consider properties such as heat, pressure, and density. For example, cold air is denser than hot air and will sink to lower levels in Earth’s atmosphere. Why […]
