The problem is to write a function to calculate the total power loss, measured in dB (decibel), under those circumstances given that:

1. rain leads to an atmospheric loss of 1.5 decibel per kilometre (dB/km)
2. wood leads to a further loss of 90 decibel per metre (dB/m)
3. to account for other unknown noise and impairments that might be present, the combined loss (obtained by adding the loss from 1 and 2) is multiplied by your individual number 1.0578. This gives you the total loss.

You can test your approach with typical values of d = 30 km and t = 0.1 m (which should result in a combined loss of 54 dB, which must then be multiplied by your individual number in order to find the total loss).

i.Include your initial decomposition of the problem in your solution document using the chevron notation (> and >>) from the module materials. The initial decomposition could start as follows:

> Calculate the total loss in dB

• ii.Include the algorithm for solving the problem in your solution document. 

iii.Write one Python function definition as explained below. Save your function in a file called Q4_OUCU.py, where OUCU is your OUCU number. When you have completed your work on this part:

• submit the .py file with your function.
• Provide a single Python function that implements the algorithm you wrote for Part (c) (ii). 
• The function should have two arguments: one for the distance d and one for the thickness t of the layer of wood.
• The function should have one return value for the total power loss.
