It will not explode since the mass of the cotton balls is so low but rather will most likely break the lock and hinges and come out.

How do you measure pressure in euros??
820 meters is the longest
Answer:
2m/s
Explanation:
Total Distance = 300m+200m = 500m
Total Time = 100s+150s = 250s
Average Speed = Total distance travelled/Total time taken
=500m/250s
=2m/s
To develop this problem it is necessary to apply the concept related to the speed of sound waves in fluids.
By definition we know that the speed would be given by
Bulk modulus
Density of air
From the expression shown above we can realize that the speed of sound is <em>inversely proportional</em> to the fluid in which it is found, in this case the air. When the density increases, the speed of sound decreases and vice versa.
According to the statement then, if the density of the air decreases due to an increase in temperature, we can conclude that the speed of sound increases when the temperature increases. <u>They are directly proportional.</u>
