What is the wavelength of 3.5 million Hz ultrasound as it travels through human tissue?
The wavelength of ultrasound can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound in human tissue is about 1540 m/s, the wavelength of 3.5 MHz ultrasound would be approximately 0.44 mm.
What restricts the flow of energy?
You can change current by altering potential difference or resistance... But assuming the voltage is constant, the resistance of the circuit restricts the flow of electrical current.
What is the wavelength of a 740 Hz sound wave?
The wavelength of a sound wave can be calculated using the formula ( \lambda = \frac{v}{f} ), where ( \lambda ) is the wavelength, ( v ) is the speed of sound, and ( f ) is the frequency. Assuming the speed of sound in air is approximately 343 meters per second at room temperature, the wavelength of a 740 Hz sound wave would be ( \lambda = \frac{343 , \text{m/s}}{740 , \text{Hz}} \approx 0.464 , \text{meters} ) or 46.4 centimeters.
The lower the frequency of a sound wave the?
For electromagnetic waves:Speed(v)=frequency(f)*wavelength(lambda)ORwavelength(lambda)=speed(v)/frequency(f)Therefore, wavelength and frequency have an Inverse relationship this means that assuming speed remains constant if the wavelength increases (gets longer) the frequency will decrease.
Find the frequency of a sound wave that has a wavelength of 1.5 meter. Could you hear this sound?
To find the frequency, use the formula: frequency = speed of sound / wavelength. Assuming the speed of sound is 343 m/s, the frequency of the sound wave would be approximately 229 Hz. Yes, this frequency is within the audible range for humans, so you would be able to hear this sound.
Is potential difference directly or inversely proportional to resistance?
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
If the force from the engine is bigger than the force of the air resistance?
The vehicle accelerates, assuming the engine is in a vehicle.
If 110 V ac is applied to the primary what is the output potential difference?
This answer should contain the amount of turns that the primary and secoundary have.
What is true about a ball falling from a height from a tower?
As the ball falls from the tower, it accelerates due to gravity. Its downward velocity increases as it falls, while its potential energy decreases. The ball's acceleration is approximately 9.81 m/s^2 (assuming no air resistance).
What happen is the potential difference across is double?
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
Potential difference across resistor is doubled?
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
What is the wavelength of a wave that has a velocity of 0.4 and a frequency of 0.2 Hz?
you need to specify the units for velocity. assuming that the velocity is in metres per second, the wavelength is 2 metres
Describe how the frequency of a wave changes as the wavelength changes?
it is directly proportional to frequency so if frequency increases wavelength also increases
What is the wavelength of sound that has a frequency of 539.8?
The wavelength of sound can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is around 343 m/s, we can calculate the wavelength of sound with a frequency of 539.8 Hz to be approximately 0.636 meters.
What is the wavelength of a 25hz sine wave?
The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.
How does resistance after current?
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
Frequency of 106.5 MHz. what wavelength would it have?
Assuming a propogation speed of 3x108 m/s (approximate speed of light), a frequency of 106.5 MHz would have a wavelength of about 2.8 m.
