A wave has a wavelength of 1.2 m and a wave speed of 24 m/s. What is the
2 answers:
Answer:A
Explanation:
From the wave formulae, wave speed= wavelength * frequency we can obtain the frequency by making it the subject of the formula
Frequency= wave speed/ wavelength
The details are found in the image attached. The frequency refers to the number of cycles covered by a wave per unit time

Answer:
1) The new pressure of the gas is 500 kilopascals.
2) The final volume is 1.44 liters.
3) Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.
Explanation:
1) From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that ,
and
, then the new pressure of the gas is:
The new pressure of the gas is 500 kilopascals.
2) Let suppose that gas experiments an isothermal process. From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that ,
and
then the new volume of the gas is:
The final volume is 1.44 liters.
3) From the Equation of State for Ideal Gases we construct the following relationship:
(1)
Where:
- Initial and final pressure, measured in kPa.
- Initial and final pressure, measured in mililiters.
If we know that , then the volume ratio is:
Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.
