Newton's second law of motion uses the formula which states that a force will cause a mass to accelerate. (f = m •
Makovka662 [10]

Newton's second law of motion can be formally stated as follows:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

This verbal statement can be expressed in equation form as follows:

a = Fnet / m

For the reaction A(g)
zubka84 [21]

Answer:

Yes

Explanation:

By definition, the equilibrium constanct, Kc, for the reaction A ⇒ 2B is

= [A]^1 / [B]^2

Substitute [A] = 4 and [B] = 2 in the equation,

[A]^1 / [B]^2

= 4^1 / 2^2

= 1

= Kc

So yes the reaction is at equilibrium.

Describe the difference between gravitational force and strong nuclear force
arsen [322]

Gravitational force is much weaker, because it is the force of gravity, or the force that makes smaller objects be pulled towards a much bigger one with a certain amount of force.

Now strong nuclear force, which is very strong, keeps the atomic particles in an atom from separating, and the reason it is so powerful is because the particles in an atom repel each other and this force keeps them from doing .that

Design an invitation you could use to calculate the density of a penny
Nataliya [291]
Firstly, the density of any substance is represented by the mass (amount of matter) as divided by the volume(amount of space). According to external websites, the mass of a penny is 2.5 grams.However, the volume of a penny is .35cm to the power of 3 (due to the thickness of the penny being extremely minimal.Thus the amount of density is extremely little). Therefore, the density of a penny is 0.875 g/cm cubed (dimensional analysis).As for an invention that could be used, that is possible with the usage of a series of measurements that can both calculate mass and volume and directly allocate that to attain density

[HELP PLEASE]What is the electronegativity from largest to smallest for Chlorine [Cl], Carbon [C], and Arsenic [As]? (hint: use
valentina_108 [34]

Answer:

Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.Explanation:
