What is a fundamental mode of vibration?
The fundamental frequency is the lowest mode of vibration of a system. If you think of a taut string, the lowest mode with which it can vibrate is the one where the centre of the string travels the maximum distance up and down so the string forms a single arc. It is also possible for it to vibrate so that two arcs (one up and one down) fit into the string, and there are many more possibilities with higher frequencies. On a stringed instrument you can hear the fundamental frequency as the normal note which the string plays, and the others as overtones. Other systems exhibit the same phenomenon.
Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
Is the maximum distance a signal can travel equal to a segment's maximum length?
It is true. The book says "The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length. Beyond this length, data loss is apt to occur."
What is maximum rang of projectile motion?
Suppose a projectile is fired from a gun, we know that "g" remains constant and as we use horizontal component of velocity in range sov0 also remains constant. Only sin2θ responsible for change in range. The range will be maximum if sin2θ has its maximum value that is 1.for maximum range:sin2θ = 12θ = sin-1 (1)θ = 90/2θ = 45 (degree)therefor if projectile is projected with the angle of 45(degree) its range will be maximum.
When does the string of a car on a roller coaster store its maximum gravitational potential energy?
Any object has maximum gravitational potential energy when it is at its highest position.
What is the maximum age limit to drive in the us?
There is no maximum. This would be considered age discrimination.
How people hear and understand the frequency of sounds?
(Not sure if this means 'How do people hear and how do they understand the frequency of sound' or 'How do people hear the frequency of sound and understand it' so I'm answering both.)The ear can be split into three basic parts: outer, middle and inner.At the outer ear, sound waves pass through the ear canal and hit the ear drum, causing the eardrum to vibrate at the frequency of the sound waves hitting it.In the middle ear, the ossicles (the 'hammer, anvil and stirrup' bones) transmit the vibrations from the eardrum to the oval window (a membrane linking the middle ear to the inner ear).The middle ear is filled with air, whereas the inner ear is filled with fluid. When sound passes between media of different densities, some of the sound is reflected and lost rather than transmitted. The ossicles help to transmit sound energy from air to fluid with as little reflection as possible. This is called impedance matching, fyi.Additionally, the way the ossicles are arranged allows for a mechanical advantage of about 1.5. This means the forces of the vibrations at the oval window are increased by half.Furthermore, the area of the oval window is around 15 times smaller than the area of the ear drum. Since pressure = force/area, this fact as well as the mechanical advantage of 1.5 means that there is a greater pressure on the oval window due to the vibrations.Essentially, the amplitude of the vibration is increased between the outer ear and middle ear.In the inner ear or cochlea, there is an organ called the Organ of Corti, in which these vibrations are turned into electrical signals and sent to the brain.Within the Organ of Corti there is the basilar membrane, which is what distinguishes the frequencies of sound.The basilar membrane is a stiff structure that is tapered on one end and is lined with hair cells. It is stiffer on one end (nearer to the oval window) and floppier on the far end.When vibrations pass through the fluid in the inner ear, the differing levels of stiffness along the basilar membrane cause different areas of the membrane to resonate at different frequencies.Higher frequency sounds cause maximum vibration (due to resonance) at the narrower, stiffer end of the basilar membrane. Lower frequency sounds resonate at the wider, floppier end of the membrane.There are more than 2000 hair cells along the basilar membrane and they are very sensitive to movement. The vibration of the membrane causes the hair cells to be displaced, and this causes pulses in nerve fibers which translates them into electrical signals that are sent to the brain.
What is the definition amplitude?
The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
What is the maximum displacement of the vibration from equilibrium position?
The amplitude.The amplitude.The amplitude.The amplitude.
Why do so many earthquakes occur along plate boundaries?
It is because the maximum vibration is in that area. The plate boundaries receive the maximum tremor.
What is the maximum age a cosigner can be?
There is no maximum age. I don't think federal law would allow any discrimination based on age.
Physics definition of a wave form caused by interference that appears not to move along the medium and that shows some regions of no vibration and other regions of maximum vibration?
standing wave
What is the amplitude of a vibration?
. The maximum distance to which an oscillating or vibrating object moves from its central position is called amplitude.
What is the maximum award that an Employment Tribunal can make against an employer if a case of discrimination is proved?
There is no limit
What is the difference between amplitude and vibration?
Amplitude- The maximum distance to which an oscillating or vibrating object moves from its central position is called amplitude. Vibration- Sound is produced by rapid -to and -fro movements ,called vibrations.
When a vibration is at maximum displacement what is its velocity?
Zero. That's the instant at which its velocity changes direction. In order to do that, its magnitude has to be zero at that point in time.
What is the primary advantage of mechanical vibration in concrete construction?
Close packing and compression of aggregates for maximum rigidity and strength after curing.
