Does changing the number of magnets in a generator affect the amount of energy produced?
No, changing the number of magnets in a generator does not directly affect the amount of energy produced. The energy produced by a generator is primarily determined by the rotation speed of the generator, the strength of the magnetic fields, and the number of turns in the coils. A generator with more magnets may have a different design that impacts its efficiency, but the number of magnets alone does not dictate the energy output.
If 25 waves are produced in 20 seconds what will be the frequecy?
25 waves are produced in 20 seconds , so 25 ÷ 20 = 1.25 waves in 1 second ... so the Frequency is 1.25 Hz
Is it true that Gene maps are produced by monitoring the frequency of crossing-over between genes?
It is true that gene maps are produced by monitoring the frequency of the crossing-over between genes. Their changes and adaptations are use in the construction of a gene map.
How can you change vibrations frequences by changing water levels?
Changing the water levels in a container can change the natural frequency of vibrations produced within that container. This is because the level of water alters the mass and stiffness of the system, impacting the vibration frequency. By filling or emptying the container, you can adjust the natural frequency of the vibrations produced.
What is the radiation source for microwaves waves?
Microwave frequency radio waves are usually produced by a MAGNETRON.
Explain about magnetostriction generator in physics?
Magnetostriction generator is used to produce ultrasonic waves. It consist of a ferromagnetic rod and an electronic oscillator.when alternating current is produced by the electronic oscillator the rod experience a small change in length with the production of ultrasonic waves...
Why not ultrasonic be produced by passing high frequency alternating current through speaker?
The ability of a speaker to produce ultrasonic output when driven with high frequency AC depends on the design (intent) of the speaker. Typical audio speakers are not designed to go ultrasonic - the cone's mass and resonate frequency just won't support it. Also, the coil reactance is too high for ultrasonic waves so they cannot be produced.
How 50Hz frequency is selected for a generator design?
Frequency is a function of engine speed and the number of poles in the generator end. For instance, a speed of 1500 RPM turning a four-pole generator will produce 50 hz. The formula is: Frequency = (poles/2) * (RPM/60) From the formula, you can see that the same frequency would be produced by a two-pole generator spinning at 3000 RPM.
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).
Which kinds of sound waves can be produced by bats?
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
Explain how ultrasonic waves can be produced in the laboratory?
Ultrasonic waves can be produced in the laboratory using a device called an ultrasonic transducer. The transducer converts electrical energy into mechanical vibrations, which generate the ultrasonic waves. These waves can be used for various applications, including medical imaging, cleaning, and material testing.
What is the frequency produced by a 4-pole generator rotating at 1800 rmin?
60 Hz (Speed) x (#poles) = 120 x (freq)
Do loud speakers produce ultrasonic sounds?
No, loud speakers typically only produce sounds within the audible range for humans, which is typically between 20 Hz to 20 kHz. Ultrasonic sounds are higher in frequency and are usually produced by specialized equipment designed for that purpose.
Can you change the wavelength of waves in a ripple tank?
Yes, you can change the wavelength of waves in a ripple tank by adjusting the frequency of the wave generator. Increasing the frequency will decrease the wavelength, while decreasing the frequency will increase the wavelength of the waves produced in the tank.
What is the difference between infrasonic and ultrasonic?
Infrasonic refers to sound waves below the frequency range of human hearing (below 20 Hz), while ultrasonic refers to sound waves above the frequency range of human hearing (above 20,000 Hz). Infrasonic waves are often produced by natural phenomena like earthquakes, while ultrasonic waves are commonly used in medical imaging and pest control.
What is the frequency produced by a 4-pole generator rotating at 3600 rpm?
f=P*N/120 f=Frequency in Hz P= No. of Poles N=Rotor Speed in Revolution per minute(rpm) for P=4 and N=3600, f comes out to be 120 Hz. So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz). The most practical situation is generator having N=3600Hz with 2 Poles. Hope It will be helpful!!!
Can an ultrasonic wave be produced by using speakers?
no Because ultrasonic sound waves are not audible and it is not possible to create that much loudness in normal speakers.
