Question
Transcribed Image Text:Assignment Overview1
This assignment focuses on the design, implementation, and testing of a Python program to
display information about the energy released by earthquakes (see below).
Assignment Specifications
For each of the following Richter scale measurements, your program will perform the
appropriate calculations and display the equivalent amount of energy in joules and in tons of
exploded TNT:
1.0
5.0
9.1 (Indonesia earthquake, 2004)
9.2 (Alaska earthquake, 1964)
9.5 (Chile earthquake, 1960; largest ever measured)
Then, your program will then prompt the user to enter a Richter scale measurement, accept a
floating-point value representing that measurement, perform the appropriate calculations, and
display the equivalent amount of energy in joules and in tons of exploded TNT for that user-
selected value.
Assignment Notes
The Richter scale is a way to quantify the magnitude of an earthquake using a base-10
logarithmic scale. The magnitude is defined as the logarithm of the ratio of the amplitude of
waves measured by a seismograph to an arbitrarily small amplitude. An earthquake that
measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures
4.0 and corresponds to a 31.6 times larger release of energy. [Rephrased from Wikipedia]

No matter how you hate it, you always have to do it since you have no other choice. Given (1) an array of prices of the items, (2) another array of the items the customer wishes to take back, and (3) the customer's payment, print the change of the customer. Input: The first number indicates the number of items "n" brought to the cashier. The next "n" numbers are the prices of the items. The next number indicates the number of items "m" that the customer wants to take back and not proceed. It is assured that 0 <= m <= n. The next "m" numbers are the items to be void that ranges from item 1 to item "n". The final number is the customer's payment. It is also assured that the given payment >= final price of items.
