Click For Summary
To determine when the sound of a ball striking the ground will be heard after dropping it from a 350m high cliff at 15 degrees Celsius, the time for the ball to fall must be calculated first. The speed of sound in air at this temperature is approximately 340 m/s. The total time includes both the fall time of the ball and the time it takes for the sound to travel back up to the observer. The calculation involves dividing the distance by the respective speeds. The final answer will provide the total time until the sound is heard.

Homework Statement



you drop a ball over the edge of a 350m high cliff. If T=15 deg celcius when will hear it strike the ground?


Homework Equations


time=distance/speed


The Attempt at a Solution


do i just divide the 350m by the speed of sound in air at 15 deg celcius?

Hi myoplex11!

Yes, just add that to the time for the ball to fall. :smile:
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
