please solve these question carefully , please make sure its correct , i just want final answer of all the three questions . i will rate if all are correct. 28) Which of the following characteristics of a wave is a measure of its intensity?: *OA) SpeedB) WavelengthC) FrequencyD) Amplitude29) What is the difference between steady state and transient state in system design?: *A) Steady state occurs at the beginning of a system response; transient occurs once asystem has settled.B) Steady state is a rapidly changing system response; transient is typically steady.© C) Transient state occurs at the beginning of a system response; steady state occurs once asystem has settled.OD) Steady state occurs until the system is steady; transient state occurs from the point ofsystem stability until a system variable changes.30) Why is mercury used in a barometer?: *A) Because its boiling temperature is lower than that of water.OB) Because its density is higher than that of water.C) Because water height at the same temperature would be much lower.OD) Because it is not liquid at room temperature like water is.
