The correct option is (b) 5n
As a result, there is a net downward force of 5N operating on the object.
The resultant force is the force that results from adding the vector sums of all the forces operating on an item. The combined action of all the acting forces on the object produces the same effect as the resulting force. When determining the resulting force, the direction of the forces must be taken into account.
Given;
The northward force is Fn = 10N
The southward force is Fs = 15N
Required;
The net force on the mobile phone is Fnet = ?N
The object's weight exerts downward pressure, and upward resistance exerts upward pressure. The vector sum of these two forces will be the net force.
Fnet = Fs - Fn (Considering the direction downward as positive)
Fnet= 15N - 10N
Fnet = 5N
As a result, there is a net downward force of 5 N operating on the object.

The fundamental quantum number, n, describes the energy of an electron and most likely separation from the nucleus.
<h3>Who or what is an electron?</h3>
A negative charges subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of atoms within about an atom is an electron that is bonded to it; the other two were protons and neutrons.
<h3>What is an example of an electron?</h3>
The smallest elemental component of an atom, the electrons has a negative charge. In an atom, there are an equal amount of protons and electrons. One electrons and one protons are all that the hydrogen atom has.

Determine PCD and CPD
First, we need to calculate CPD
Since DPA is a straight line and CPA = 100;
We have that:
--- angle on a straight theorem
Substitute 100 for CPA
Subtract 100 from both sides
Next, we calculate PCD
We have that:
--alternate angle
In triangle PCD
--- angles in a triangle
Where
So, we have:
Subtract 136 from both sides
A) The acceleration of this car is zero
Because, the question states that it is traveling at a constant velocity, meaning that it has no acceleration at all.
