How high or low a sound seems to a listener is its?

How high or low a sound seems to a listener is its? How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for […]

What is a disadvantage of using nuclear power?

What is a disadvantage of using nuclear power? Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste. What is the cheapest form of electricity? solar […]

What are the four main causes of urban sprawl?

What are the four main causes of urban sprawl? As a summarize, it has done many studies about causes of urban sprawl that the most important factors are population and income growth, low price of land and access to appropriate housing, some advantages such as low price of transportation systems, promotion of commuting network, new […]

What is the most slippery metal?

What is the most slippery metal? In fact, the low static coefficient of fric- tion of Teflon-on-Teflon, 0.04, made it the most slippery solid substance on earth. Further experimentation revealed the reasons for these properties: the carbon backbone of the polymer chain was com- pletely surrounded by fluorine atoms. Why is friction less on snow […]

How do you tell if a capacitor has failed?

How do you tell if a capacitor has failed? Use the multimeter and read the voltage on the capacitor leads. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should […]

What is the average force on the ball?

What is the average force on the ball? Using Newton’s second law we can estimate the average force acting on the ball during the hit: Plugging in the numbers we find the average force to be Favg=18,436 N, which is equivalent to 4124 lbs of force. How much force did the racket exert on the […]

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 culture affect health?

How does culture affect health? Culture influences healthcare at all levels, including communications and interactions with doctors and nurses, health disparities, health care outcomes, and even the illness experience itself.
