Two sources each emit sound power uniformly in alldirections.
there are no reflections. both sources arelocated on the x-axis,
one at the origin and the other at x = +123m. the source at the
origin emits four times more power thanthe other source. where on
the x axis is the intensity ofeach source equal? note that there
are two answers.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
