You are a sound engineer working on a music festival and need to calculate the speed of sound in the air. You measure the distance between the sound source and a microphone to be 10 meters and the time it takes for the sound to reach the microphone to be 0.05 seconds. What is the speed of sound in the air? (Units: speed - meters per second (m/s), distance - meters (m), time - seconds (s))
2 You are an electrician w orking on a circuit. You need to calculate the electric current flowing through a wire with a resistance of 10 ohms and a voltage of 50 volts. What is the electric current flowing through the wire? If the wire has a length of 10 meters and a cross - sectiona l area of 0.5 square meters, what is the electric conductivity of the wire? (Units: current - amperes (A), resistance - ohms (Ω), voltage - volts (V), length - meters (m), cross - sectional area - square meters (m^2), electric conductivity - siemens per mete r (S/m))
