Question

Part 3 only

Your can use the following template to help layout your code:
# Don't forget Name and ID.
# Don't forget to place your imports here.
def calculate_distance(first_intensity, second_intensity):
# implement your solution here
# return distance
#Ask user for itensity1
#Ask user for itensity2
# Validate your intensities.
# In your if, elif, else block(s), you will need to place this
# in the case where the distance is valid
distance = calculate_distance(intensity1, intensity2)
#Print results
Part 3:
Modify your program slightly so that you now take both intensities using a single
input() statement. The user will enter the two values separated by a 'space' character
(e.g., 10 5).
Hints:
Remember the split() string method covered in the class? Can you use this here?
O Remember that you will need to cast the values to floats once you obtain
the two measurements.
Part 4:
It turns out that your measurement device isn't very accurate and gives you slightly
different values each time you measure the intensity at a location. In order to obtain a
good estimate of the distance from the speaker and its power, you decide to repeat your
experiment multiple times and record the distance and power values for each run. You
then find the trimmed average of both the distance values and power values obtained
across your experiment.
Trimmed average or conservative average here is defined as the average of a list of
numbers ignoring the largest and smallest values. This was covered in a tutorial session
on lists, so feel free to refer to the appropriate content on D2L if you need a refresher.

Imagine that you are on a straight, flat road. Some distance ahead, you spot a speaker
playing some music. You want to work out: 1) The distance of the speaker from your
location, and 2) the power of the source speaker. Unfortunately, you are unable to get
any closer to the source from your location, so you have to find an alternative way of
estimating its power and distance. Use the image above to help you visualise the
problem. Fortunately for you, you have a device that measures the intensity of sound at
your location. How do you go about using the intensity information to work out the
distance and power of the speaker?
1 =
According to laws of physics, under ideal conditions, sound propagates outwards from a
source in a radial fashion. Therefore, given the distance (r) (in metres) and the source
power (P) (in Watts), the intensity of sound (I) (in Watts/metre^2) at that distance is
given by the equation:

Feel free to search the internet for more background on the inverse square law. For this
problem, you can assume that there is nothing between you and the speaker to absorb
or reflect any part of the sound, you can ignore the effect of the ground on the sound
waves, and that the speaker is at the same height as you (i.e., ignore the effect of
height). Your device measures the intensity in Watts per Squared Meter. To determine
the distance and power, you are smart enough to realize you need two measurements,
so you take 1 measurement (1₁) at your current location and take another one (1₂) after

Document A Source: John Locke, Second Treatise on Civil Government, 1690. Note: John Locke (1632-1704) lived in England during both the English Civil War and the Glorious Revolution. When Locke was born, England's form of government was an absolute monarchy in which the king or queen had power to rule and sometimes asked for advice and assistance from Parliament. In 1689, the English Parliament passed the Bill of Rights. This law reversed the role of king and Parliament making Parliament more powerful than the king. 2 3 "Of the State of Nature" (W)e must consider, what state all men are naturally in, and that is, a state of per- fect freedom to order their actions, and dispose [manage] of their possessions and per- sons, as they think fit, within the bounds of the law of nature....
