A guitar amplifier during a solo at a rock concert produces sound with a power of 40 W. Assume that the sound waves emit and spread spherically. A) What is the intensity of the sound waves as they reach a fan in the front row 16 meters from the amplifier?

B) What about in the back, 53 meters away?

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
