Net force is the sum of all forces acting on an object. For example, in a tug of war, when one team is pulling the rope with a force of 100 N and the other with 80 N, the net force would be 20 N at the direction of the first team (10

20N toward the first team.

Explanation:

The net force is the resultant force that replaces the summation of the individual forces acting on a body.

Now in the game of a tug of war, let the summation of forces to the right be positive and the summation of forces to the left be negative

forces.

hence the summation of positive and negative forces must equal zero

that is,

100-80=0

20=0

Hence the resultant or the net force is 20N, and the direction tends towards the direction of the larger force which is to the right of the first team.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
