Solve the problem.The Bay area of California was shaken by an earthquake on October 17, 1989. The epicenter was located at Loma Prieta. The diameter of the earthquake's horizontal waves that shocked the area measured about 120 miles. How many square miles were affected by this earthquake?

Answers

As the shock waves travel in concentric outward circles from the epicenter, and the diameter is measured 120 miles,
area of a circle =πr*r

d=120
r=120/2r=6060*60=36003600*π=11309.734
11309.734 square miles

An electric buzzer is activated, then sealed inside a glass chamber. When all of the air is pumped out of the chamber, how is the sound from the buzzer affected?The sound is silenced.
The wavelength of the sound increases.
The frequency of the sound increases.
The wave speed of the sound increases.

Answers


The answer is that the sound is increased because the sound waves are mechanical waves, this means that they can't travel trough empty space they need a medium to travel.

Answer:
