The half wave potential is calculated by finding the voltage at which half of the peak current is observed during a cyclic voltammetry experiment. It is typically determined by locating the voltage at which the current is at 50% of its maximum value in the anodic or cathodic peak. This value can be read directly from the voltammogram obtained during the experiment.

What properity o a wave changes to create the Doppler effect?

The frequency of the wave changes to create the Doppler effect. As the source of the wave (like a moving car) moves relative to the observer, the frequency of the wave appears to change to the observer due to the compression or stretching of the wave.


What sound is produced when the shock wave formed at the nose of an artifact traveling at supersonic speeds reaches the ground?

The sound of a sonic boom is the engine noise and vibration of the aircraft, only greatly amplified. Sound is a reverberating pressure wave that travels through air at a constant rate. Sound waves move away from the plane in all directions as it travels, but at the speed of sound these pressure waves at the nose can't get clear of the plane and so begin to 'stack' together, resulting in a much stronger wave and an extremely loud noise. O> = the plane ( ( ) ) = sound waves at rest: ( ( ( ( O> ) ) ) ) Subsonic flight: Sound in front is a higher frequency ( ( ( O> ) ) ) ) ) ) Sonic boom: Sounds can no longer escape directly in front ( ( ( O>) Supersonic flight: Plane is outrunning its own sound () ) ) )() ) ) )() ) ) )( O>


O calculate pressure it is necessary to know the force and what?

To calculate pressure, you need to know the force applied perpendicular to the surface and the area over which the force is distributed. Pressure is calculated by dividing the force by the area, so both of these components are essential in determining the pressure on a surface.


A pipe that is closed at one end can be made to resonate by a tuning fork at a length of 0.25m. The next resonant length is o.75m(speed of sound is 338ms). (a) calculate the wavelength of the sound em?

The wavelength of the sound wave can be calculated using the formula: wavelength = 4 * length. Given the first resonant length is 0.25m, the wavelength for this resonant mode would be 4 * 0.25m = 1m. Similarly, for the next resonant length of 0.75m, the wavelength would be 4 * 0.75m = 3m.


What is the relationship between the frequency o a light wave and its energy?

The energy of a light wave is directly proportional to its frequency. This means that light waves with higher frequencies have higher energies, while light waves with lower frequencies have lower energies. This relationship is described by Planck's equation E = h*f, where E is energy, h is Planck's constant, and f is frequency.

What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?

The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.

What is potential step from 1 potential to o potential?

When there is a potential difference between two points, such as from 1 potential to 0 potential, it means that there is a voltage drop of 1 unit in the direction from higher potential to lower potential. This difference in potential creates an electric field that can drive the flow of electric charge.
