Why did different size of blocks of wood have the same density?
Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
What is the standard unit of amplitude?
As radio frequency, in would be modulation in hertz, kilohertz, megahertz. In other areas of measure it could be peak-to-peak. I.E. the maximum absolute value of some quantity that varies, usually with regular frequency. The unit of amplitude depends specifically on the type of wave, certain mechanical waves (e.g. those in in a plucked guitar string) have amplitudes measured in metres. Pressure waves (such as sound) have the unit of pressure as their amplitude (Pascals) where as electromagnetic waves use the electric field strength in volts/metre as the unit of amplitude. As you look at an oscilloscope, the vertical peak of a waveform From Wikipedia: The maximum absolute value of the vertical component of a curve or function, especially one that is periodic.
What unit of measure is used for gas?
That depends what aspect of the gas you want to measure: its volume, its pressure, its temperature, its density, etc.
What unit would you use to calculate density?
density= mass/volume
What is the unit of flux density?
Tesla.
What is the units and symbol for amplitude?
The unit for amplitude is the same as the quantity being measured. For example, for sound waves, the unit could be decibels (dB). There is no specific symbol for amplitude as it depends on the context, but it is often represented by "A" or "Α".
What is the si unit for amplitude?
Amplitude is used for different waves. For a water wave, the amplitude might be measured in units of length (meters or centimeters), for a sound wave, in units of pressure, for an electromagnetic wave, in terms of electrical properties, for an electrical signal, in volts, etc. - so it really depends on the kind of wave.
What is the SI unit of amplitude for sound?
The SI unit for the amplitude of sound is decibel. It is written as dB.
What does pressure equal?
Pressure is the same as force / unit area.
What is the law of density?
The law of density states that the density of a substance remains constant under uniform conditions of temperature and pressure. It means that the mass of a substance per unit volume remains the same, regardless of the size of the sample. Mathematically, density is calculated by dividing the mass of an object by its volume.
What is the density of 10 gallons of a liquid?
To calculate the density of 10 gallons of a liquid, you need to know the mass of the liquid. Density is defined as mass per unit volume. Without the mass of the liquid, you cannot determine its density.
What does energy pressure mean?
Pressure energy per unit volume is equal to the pressure and per unit mass is equal to the density of the liquid. When an incompressible liquid flows out of a tank in which the pressure is maintained , the liquid under pressure possesses potential energy.
Is the unit associated with amplitude is the hertz?
No, the unit associated with amplitude is not hertz. Amplitude is a measure of the maximum displacement or distance a wave varies from its rest position. The unit for amplitude is typically meters (m) for most practical applications. Hertz (Hz) is the unit for frequency, which measures the number of cycles of a wave that occur in one second.
How does the amplitude of a sound relate to its intensity?
The amplitude of a sound wave is directly related to its intensity. A higher amplitude corresponds to a louder sound with greater intensity, while a lower amplitude corresponds to a softer sound with lower intensity. Intensity is the amount of energy carried by the sound wave per unit area.
How does the density of one marble compare with the density of six of the marbles?
The density of one marble is the same as the density of six marbles when compared in terms of mass per unit volume. Since the density remains constant regardless of the number of marbles, the ratio of their densities is 1:6.
What is the specific gravity of solid materials?
The same as their g/cm3 density, but with no units. It is the density of that material relative to the density of water. Since water has a density of 1g/cm3 the previous answer is correct, but it is more powerful than that. If you know the density in any unit system and divide it by the density of water in that same unit system, you will get the specific gravity.
What does the energy of a mechanical wave depend on?
The energy of a mechanical wave depends on its amplitude and frequency. The greater the amplitude (height or intensity) and frequency (number of waves per second), the higher the energy carried by the wave.
