The temperature of air varies with height linearly from T_(1) at the earth's surface to T_(2) at a height h. Calculate the time t needed for a sound wave produced at a height x to reach the earth's surface. The velocity of sound near the earth's surface is C.

1.	The temperature of air varies with height linearly from T_(1) at the earth's surface to T_(2) at a height h. Calculate the time t needed for a sound wave produced at a height x to reach the earth's surface. The velocity of sound near the earth's surface is C.
Answer» Answer :`(2H)/C sqrt(T_(1))/(T_(1)-T_(2))[sqrt(T_(1))-sqrt(T_(1)-(T_(1)-T_(2))x/h)" "]`
