An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left. what is the magnitude and direction of the net force?
a. 9 newtons to the right
b. 9 newtons to the left
c. 22 newtons to the right
d. 35 newtons to the right
e. 35 newtons to the left

Option A)

9 newtons to the right

A resultant/net force is the single force obtained by combining a system of forces acting on a rigid body.

Given in the question,

right = +

left = -

As force is vector quantity so direction matters hence,

resultant force = (+22 -13) N

                        = +9 N

                        = 9 N to the right      

the answer for sodium is 0.186

the answer for rubidium is 0.251

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
