The force of a system can be measured by formula P=mf where P is the force, m is the mass of the system and f is the acceleration of the system. The formula is known as Newton's second law of motion.

Answer from: metatiley

The definition of force is given by the secon Law of Newton: Force = mass * acceleration.

So, the basic components of the formula for finding force are mass and acceleration. That is, if you know the mass of an object and the acceleration of it, you can find the external force (the net external force) that is acting over the object.

There are other formulas for finding force for special systems. For example, for springs, you use the law of Hook: Force = - k *x^2. Where k is the elastic constant of the spring and x is the displacement from the equilibrium point.

So, depending on the contex you could need different formulas. Without more contex I'd say you are talking about the second law of Newton: Force = mass * acceleration.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form( $n_2$ ) .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
