Whether the sound produced by a seconds pendulum is infrasonic or ultrasonic?

Infrasonic denotes any sound that is at a frequency below the human capability of hearing, this is around 5-25Hz. Ultrasonic on the other hand is, conversely, a frequency that is above the human hearing range (over 20,000Hz).

What are disadvantages of friction?
As might be expected from its early invention, the verge is the most inaccurate of the widely-used escapements. It suffers from these problems:Verge clocks are sensitive to changes in the drive force; they slow down as the mainspring unwinds. This is called lack of isochronism. It was much worse in verge and foliot clocks due to the lack of a balance spring, but is a problem in all verge movements. In fact, the standard method of adjusting the rate of early verge watches was to alter the force of the mainspring.[20] The cause of this problem is that the verge is a frictionaltype escapement. The crown wheel teeth are always pushing on the pallets, driving the pendulum (or balance wheel) throughout its cycle; it is never allowed to swing freely. All verge watches and spring driven clocks required fusees to equalize the force of the mainspring to achieve even minimal accuracy.It is a recoil type escapement, meaning that the momentum of the foliot or pendulum causes the wheel train to move backward during part of its cycle. This increases friction and wear, resulting in inaccuracy. One way to tell whether an antique watch has a verge escapement is to observe the second hand closely; if it moves backward a little during each cycle, the watch is a verge.In pendulum clocks, the wide pendulum swing angles of 80°-100° required by the verge cause an additional lack of isochronism due to circular error.The wide pendulum swings also cause a lot of air friction, reducing the accuracy of the pendulum, and requiring a lot of power to keep it going, increasing wear.[21] So verge pendulum clocks had lighter bobs, which reduced accuracy
What is the type of pitch produced when a loud objects has passed you?
When a loud object such as a train passes you, there is what is officially known as the Doppler Effect, by which the sound has a higher pitch as the object approaches, and a lower pitch as it passes. The speed of the object, whether approaching or receding, affects the wavelength of the sound.
When is an experimental variable good and when should it be reduced or eliminated?
There are generally 3 variable in an experiment : the dependent, independent and the control variable. The independent variable is something you change in your experiment and affects the dependent variable, while the control variable is there to make sure the experiment is a fair test. (eliminate external factors) A variable is considered good when it allows you to find a relationship or to investigate your theory. eg. A simple experiment : To investigate whether length of pendulum affects the period of a pendulum. IN this case, your independent variable would be the length of pendulum(to be changed) while your dependent variable is the time taken for 1 oscillation. You can plot x-y graphs to find the relationship between the two to help you conclude your experiment. ( Wind factor should be eliminated as it will affect your readings). There is no control variable for this experiment as period is dependent only on length and gravity.(unless gravitational force changes) There are times when a variable can be affected by many other factors. So in your experiment, you might want to eliminate those factor so that you can make a conclusion.

Investigate whether a simple pendulum will swing continuously in air.Explain your finding?
A simple pendulum will definitely not swing continuously in air. The pendulum would lose energy to its surroundings in overcoming air resistance.
What is the definition of the period of a pendulum?
Don't know whether this is right but ... The period of a pendulum is the time required for one complete cycle - a swing from right to left :)
What is critical in determining whether something is produced a public good?
It is critical in determining whether something is produced a public good if the benefit is greater than the cost.
Whether the period of a pendulum is influenced by the point from which it is released?
Yes as the momentum is greater although now that i think about it it may only effect the speed only
What is critical in determine whether something is produced as a public good?
whether or not the goods can be withheld or not from 1 individual consumer
When a fuel burns what determines whether co or co2 will be produced?
Whether air or oxygen is limiting or present in excess
What is a critical factor in determining whether something gets produced as a public good-?
A critical factor in determine whether something gets produced as a public good is if the benefits are are greater than the cost.
What is a critical factor in determining whether something gets produced as a public good?
Whether the benefits to society are greater than the total cost determines if something is produced for the public good. or cost
How can you tell whether a compound reacts with bromine?

What determines whether a pendulum swings in a plane or describes a three-dimensional path?
A pendulum on a knife edge bearing may swing back and forth in a plane (relative to the Earth). A pendulum suspended from aneedle bearingmay swing in elliptical fashion on the surface of a sphere.For the movement to stay parallel to a plane which is fixed relative to the stars, the pendulum must have a needle bearing but no initial momentum perpendicular to that plane. However, the origin of that plane will follow the daily and yearly movements of its location on the Earth. Relative to the Earth, such a pendulum's path will appear to rotate once around every sidereal day (23 hours, 56 minutes, 4 seconds).
How do you use an ultrasonic cleaner to clean firearms?
You use it to clean firearms just like you use it to clean anything else. You put the parts in the cleaner and turn it on. There is some disagreement on whether cleaning a gun in an ultrasonic cleaner is a good idea. I've never done it, but I know several people who do. As far as we can tell, it hasn't caused any problems.
Why is what to produce a problem in every economy?
What to produce?There are two aspects of this problem--- firstly, which goods should be produced, and secondly, what should be the quantities of the goods that are to be produced. The first problem relates to the goods which are to be produced. In other words, what goods should be produced? An economy wants many things but all these cannot be produced with the available resources.Therefore, an economy has to choose what goods should be produced and what goods should not be. In other words, whether consumer goods should be produced or producer goods or whether general goods should be produced or capital goods or whether civil goods should be produced or defense goods. The second problem is what should be the quantities of the goods that are to be produced.Production of goods depends upon the use of resources. Hence, this problem is the problem of allocation of resources. If we allocate more resources for the production of one commodity, the re­sources for the production of other commodities would be less.
