Answer:
Code is completed below
Explanation:
Source Code in Java:
class Parenthesis
{
boolean hasBalancedParentheses(String eq) //method to check and return if a set of parenthesis is balanced or not
{
int count=0; //to store count of current unclosed opening brackets
for(int i=0;i<eq.length();i++)
{
if(eq.charAt(i)=='(')
count++;
else if(eq.charAt(i)==')')
count--;
if(count<0) //if count falls below zero, there were more closing brackets than opening brackets till this point
return false;
}
if(count>0) //if count is still more than zero, there were less closing brackets than opening brackets
return false;
return true; //if program reaches this point, it has passed all the tests
}
public static void main(String args[])
{
//testing the function
Parenthesis ob=new Parenthesis();
System.out.println(ob.hasBalancedParentheses("()(()())((())())"));
System.out.println(ob.hasBalancedParentheses(")((()())(()))())"));
}
}

Answer:
a.the number of cycles per second
Explanation:
The frequency of a sine wave is defined as the number of cycles per second.
Frequency is the inverse of the time period. The frequency of a sine wave is given by 1/TimePeriod . It is generally expressed in units of Hertz(Hz) or sec^-1. Larger the time period, lower will be the frequency and vice versa. So for higher frequency waves we need to ensure that the time period is small.
it's not necessary in a field to have .
Answer:
