everyone. This is Question number six from chapter 17 and this problem we're given that the air temperature in the Sahara reaches 56 degrees Celsius were asked to find the speed of sound in air at that temperature. So we have an equation from Chapter 17 point to that relates speed of sound to air temperature. And that's right here. B w speed of sound equals 3 31 meters per second times T over to 73 t. Here's your temperature, air temperature and Calvin. So first things first we need to convert this 56 degrees Celsius to Calvin. So we do that with our basic conversion 56 plus 2 73 And that's gonna give you 329 k. And then we can just go ahead and plug in this equation. And so so we w equals 3 31 times 3 29 K over to 73 k. And when you put that into your calculator, you get an air speed, um 3 63.37 meters per second
