Explicación
Horsepower is a unit of power used to measure the output of engines. Among the options provided:1. A tachometer is an instrument that measures the rotation speed of a shaft or disk, as in a motor or other machine. It does not measure power.2. A dynamometer is a device used to measure force. In the context of engines, it measures the power output of the engine, making it the correct answer.3. An ammeter is an instrument for measuring electric current in amperes. It does not measure power.4. An ohmmeter is an electrical measuring instrument that measures electrical resistance, the opposition to the flow of an electric current. It does not measure power.Therefore, the correct answer is the dynamometer, which is used to measure horsepower.
