Han stands at the rim of the Grand Canyon and yodels down to the bottom. He hears the yodel echo back from the canyon 5.20 seconds later. If sound travels at 340 m/s in air, how deep is the canyon at this location? [Hint: The answer is not equal to 1768 meters]

884 meters

Explanation:

h=(340 m/s) x (5.2 s)=1,768

1,768/2=884 meters!

Hope this helped!

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
