Two speakers create identical 288 Hz sound waves. A person is 1.47 m from Speaker 1. What is the minimum distance to Speaker 2 for there to be constructive interference at that spot?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Física: un futbolista patea hacia el arco con una velocidad de 15m/ah, calcular: a)el alcance para un ángulo de tiro de 25º, b) el tiempo que el balón permanece en el aire.
