*This question seems like an opinion based question, but here is my opinion on the matter:
Yes the cell phone is changing our views of what is polite and impolite. It is indeed impolite to talk on your phone while you are ordering a drink at Starbucks, because then you aren't focusing on ordering instead you are focused on your phone call which can interfere with your ordering.
Hope this helps!
Answer:
The complete program is as follows:
m_str = input('Input m: ')
mass = float(m_str)
e = mass * 300000000**2
print("e = ",e)
Explanation:
This is an unchanged part of the program
m_str = input('Input m: ')
This converts m_str to float
mass = float(m_str)
This calculates the energy, e
e = mass * 300000000**2
This is an unchanged part of the program
print("e = ",e)
