Net force refers to the sum of all the forces that act upon an object.

Option B

<u>Explanation:</u>

The forces acting on an object can be exerted from n number of directions and angles.If the force acting on an object is applied along the direction of the motion of the object, then it is termed as positive force. But if the force is required to stop an object from motion, then it will be termed as negative force.

So the sum of all the force acting on the object will be termed as net force which is the vector sum of all the forces acting on the object. Thus, net force refers to the sum of all the forces that act upon an object.

Answer:

hello your question is incomplete attached below is the complete question

Pyridinium  ion is more soluble in 0.1 M HCL (aqueous solution) and this is because the Pyridine ion reacts with NaOH  and after the reaction it comes out neutral.

N-acetyltyrosine methyl ester is more soluble in 0.1 M HCL while

What is the number of moles in 15.0 g AsH3?
pentagon [3]

We are given with the mass of Arsine (AsH_{3}

The mass of arsine is 15g

there is a relation between moles, mass and molar mass of any compound which is

moles=\frac{mass}{molarmass}

The molar mass of Arsine = atomic mass of As + 3X atomic mass of H

the molar mass of Arsine = 74.92 + 3X 1 = 77.92 g/mol

Let us calculate the moles as

moles=\frac{15}{77.92}=0.192mol
