The speed of sound depends on the medium in which it is transported.
Sound travels fastest through solids, slower through liquids and slowest through gases.
So it will travel slowest through water at 55 degrees

Answer:
30 miles people hour (mph)
Explanation:
The maximum speed for one flat tyre is 30mph, for both tyres it is 20 mph and for two tyres on the same side it is 30mph. When a tyre is punctured driving at high speed should be avoided and not too long distance should be covered to avoid further accident and for the safety of other vehicles. Speed limit and distance for flat tires should be strictly followed.
Answer:
The current in the second wire is 4.4 A.
Explanation:
Given that,
Distance =7.0 cm
Current in first wire = 2.0 A
The magnetic field strength is zero at distance of 2.2 cm from the first wire.
We need to calculate the current in the second wire
Using formula of magnetic field
Here, 
Put the value into the formula
Hence, The current in the second wire is 4.4 A.
