To solve the problem, we need to determine the velocity of sound in brass based on the given information. Here’s a step-by-step solution: ### Step 1: Understand the Problem We have a brass bar that is 1 km (1000 meters) long. A sound source is placed at one end, and two sounds are heard at the other end with an interval of 2.6 seconds. We need to find the velocity of sound in brass. ### Step 2: Calculate the Time Taken for Sound to Travel in Air The speed of sound in air is given as 330 m/s. We can calculate the time taken for sound to travel 1 km in air using the formula: \[ ...
