Beginning when the bottom of the object first touches the water,
and as it descends and more and more of it goes under, the
buoyant force on it increases during that time.
As soon as the object is completely underwater, it doesn't matter
how deep under it is, the buoyant force on it remains the same.
Answer:
Explanation:
We know that speed is defined as distance moved per unit time hence expressed as 
where v is speed in m/s, d is distance in m and t is time in seconds. Making d the subject of the above formula then
Substituting 343 m/s for d and 10 s for t then
Therefore, the distance between speaker and deter is

Explanation:
Why Cannot we hear an echo in a small room?
They can't hear an echo in small room because in it the sound can't be reflected back. For an echo of a sound to be heard,the minimum distance between the source of sound and the walls of the room should be 17.2 m.Obviously,in a small room echoes cannot be heard.
Einstein's theory of General Relativity states that space-time is able to be warped in the presence of mass or energy. This warping is what "tells" matter how to move in its presence. In the paraphrased words of physicist John Wheeler, matter tells space-time how to warp, and warped space-time tells matter how to move.
