Answer:
A) 3.11 Hrs
Explanation:
Wave speed is given by the formula
now we will have
now the time taken by the wave to move the distance 560 km is given as
t = 3.11 hours
To solve the problem, we can use Charle's law, which states that for an ideal gas at constant pressure the ratio between absolute temperature T and volume V remains constant:
For a gas transformation, this law can be rewritten as
(1)
where 1 and 2 label the initial and final conditions of the gas.
Before applying the law, we must convert the temperatures in Kelvin:
The initial volume of the gas is
, so if we re-arrange (1) we find the new volume of the gas:
