Assume there is a variable, h already associated with a positive integer value. Write the code necessary to compute the sum of the perfect squares whose value is less than h, starting with 1. (A perfect square is an integer like 9, 16, 25, 36 that is equal to the square of another integer (in this case 3*3, 4*4, 5*5, 6*6 respectively).) Associate the sum you compute with the variable q. For example, if h is 19, you would assign 30 to q because the perfect squares (starting with 1) that are less than h are: 1, 4, 9, 16 and 30

int i=1  // initialized i to 1

int q=0  // initialized q to 10

while((i*i)<h) // iterating the while loop

{

q=(i*i)+q  // calculating the sum of square

i=i+1 //Increment of i

}

Explanation:

Following are the description of Program

Initialized the variable "i" which is "int" type to 1.Initialized the variable "q" which is "int" type to 0.Iterating the while loop to less then variable "h".In this loop we calculate the sum of square and holding the result in the variable "q".Finally increment the value to "i" by 1 to iterating the loop.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
