Answer:

At 85°C the substance is already in liquid form. Now adding more heat increases the random motion of the constituent molecules of the substance this random motion goes on increasing till the molecules reach to temperature of 140°C where the molecules are enough energetic to leave the surface of liquid hence turning into gas. after that the energy supplied try to increase again the random motion of molecules in gas . This process goes on till the gas molecules reach to temperature of 145°C

14) Modify the method that calculates the sum of the integers between 1 and N. Have the new version match the following recursiv
Setler [38]

Explanation:

Let solve the program using Java programming language

Method: method means group of statements to perform some operation.

             let call the method sum.

Parameters: list of variables that are use in the method for declaration.

<u>The code</u>

public int sum (int number)

int answer;

if (number == 1)

answer = number;

else

{

int half = number/2;

int span = number - half;

answer = sum(half) + sum(span) + (half * span);

}

answer result;

}

Firstly we defined the method called sum(), the method takes only one parameter which is number and return the answer(sum of  the integers 1 and N).

if the number is equal to 1, so it will return the number and if the number is not equal to 1 it will divide the number by 2 and get the span(span used to shift upper range).And result will add sum of half, sum of span and product of half span.

Two heavy objects of masses 1 kg and 2 kg are moving towards each other under
SOVA2 [1]

The acceleration of the body in terms of the gravitational constant G is G.

According to Newton's law of universal gravitation;

F = Gm1m2/r^2

G = gravitational constant

m1 = mass of the first body

m2 = mass of the second body

r = distance between the two bodies

Substituting values to find the force on the two bodies;

F = G × 1  × 2/1^2

F = 2G

For the 2 Kg mass

F = ma

m = mass

a = acceleration

F = gravitational force

Hence,

2G = 2a

a = 2G/2

a = G
