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]

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

because if the tool that you are using is not balanced it there would be false mass.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
