8. What is the speed of a wave that has a wavelength of 150 m and a frequency of 540 hz?

The speed of the wave is 81000 m/s.

Explanation:

The formula of the speed of a wave is frequency x wavelength.

Therefore, multiply 540 times 150.

You get 81000 m/s which is the correct answer

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
