Answer:

i. The rock can be referred to as the bob.

ii. The point at which the string was held can be referred to as the pivot.

iii. The length of the string from its point of suspension to the rock is the given length of the pendulum.

Explanation:

A pendulum is a weight suspended from a pivot so that it can freely perform an oscillatory motion. It consists of majorly three parts: bob, pivot and length. Its motion deals with the conversion of kinetic energy to potential energy, and vice versa. When set in motion, at the extreme ends of its oscillation, it has maximum potential energy. But when at the mid-point of the curve path, it has maximum kinetic energy.

Some of its properties can be used to describe other objects.

For the given pendulum, the rock represents the bob, the point at which the string was held is the pivot, and the length of the string fom pivot to bob is the length of the pendulum.

Your hand is the pivot or the fulcrum. It is where the pendulum swings from. The string is the lever; it holds the weight and undergoes tension forces. The stone is the load. It can be put to some certain height and cause the swinging.

Assume that you have an array of integers named arr. The following program segment is intended to sum arr [0]through arr[n−1], w
Paladinen [302]

Answer:

There is only one modification in the above loop i.e. while loop should be like this--

while (i != n)

     {

         sum+=arr[i];   // Line 1, In question segment it is line 2.

          i++;                // Line 2,  In question segment it is line 1.

     }

Output:

Now if the array input is 1,2,3,4,5 then the output is 15.

Explanation:

In the above question, all the line of the segment is right except the body of the loop because--

  • The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop
  • The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].
  • So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).

Now It gives the correct output because it can add arr[0] to arr[n-1].
