Two speakers, in phase with each other, both put out sound of frequency 260 Hz. A receiver is 2.50 m from one speaker and distance x from the other, where x > 2.50 m. What is the smallest value of x such that the receiver detects maximum constructive interference?

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

they should be similar or the same

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
