Asolid contains n mutually noninteracting nuclei of spin 1. each nucleus can therefore be in any of three quantum states labeled by the quantum number m, where m = 0, ±1. due to the electric interactions with the internal fields in the solid, a nucleus in the state m = 1 or in the state m = 1 has the same energy " > 0, while its energy in the state m = 0 is zero. (a) write the partition function in a canonical ensemble for this system of n nuclei

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).

Experimental data that is expressed using numbers is said to be

Helen's credit card has an apr of 15.32% and a grace period of 17 days and helen pays her balance in the full every month. if her last billing cycle ended on september 26, 2009, and she made her payment on october 11, 2009, did she owe any interest on her last statement's balance?
