Write a program that ask the user to enter air water or steele and the distance that a sound wave will travel in the medium the program should then display the amount of the time it will take you can calculate the amount of time it takes sound to travel in air with the following formula time = distance/1,100 you can calculate the amount of time it takes sound to travel in water with the following formula time = distance/ 4,900 you can calculate the amount of time it takes sound to travel in steel with the following formula time = distance/16,400

What are procedures that keep a data base current

I'm taking a class on how to make a movie, and it offers some apps that would be in the process. the thing is, i don't have any of those ha. if you have any tips on some apps i could use, that would be awesome. i don't have an iphone, so don't suggest any apps like imovie. i know that this is a weird question, but it would be super for me. : )

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
