) Determine the pressure difference (in bar and in psi) between the inside and outside of an ultra-small air droplet near the surface of water given that the droplet diameter is

Complete Question

The complete question is shown on the first uploaded image

a

b

c

Explanation:

From the question we are told that

Generally the pressure difference is mathematically represented as

Considering question a

Here  the diameter is  

Generally the radius is mathematically represented as

So

=>    

Converting to bar

Converting to psi  

Considering question b

Here  the diameter is  

Generally the radius is mathematically represented as

So

=>    

Converting to bar

Converting to psi  

Considering question c

Here  the diameter is  

Generally the radius is mathematically represented as

So

=>    

Converting to bar

Converting to psi  

the total distance traveled by the car is

30km + 49km = 79 km .
