3) A power company charges 6.6 cents per kilowatt hour (KWH) for providing electricity. Write a script power_charge that will prompt the user for the number of KWH used in a given month, and will print the charge for the month in dollars, in the following format. (The conversion is 100 cents in one dollar.) Here are examples of using the script.
>> power_charge
How many KWH this month: 200
Your charge for 200 KWH will be $13.20.
>> help power_charge
Calculates and prints charge to customer for electricity
4) For a bubble, the surface tension force in the downward direction is
Fd = 4 T r
where T is the surface tension measured in force per unit length and r is the radius of the bubble. For water, the surface tension at 25C is 72 dyn/cm. Write a script surftens that will prompt the user for the radius of a water bubble in centimeters, calculate Fd, and print it in a sentence (ignoring units for simplicity). Assume that the temperature of the water is 25C so use 72 for T.
