<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
B. all of nature follows uniform, unchaining laws.
Answer: 4 is the subscript in
.
Explanation:
We know that,
Subscript: The number of atom present in a given compound.
In
, 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.
Coefficient: Number of atom which is used in reaction.
For example: In
, 3 is the coefficient of silicon tetra chloride.
A Product : In the balance equation, right hand side is called product.
A reactant : In the balance equation, left hand side is called reactant.
For example: the balance equation is

In this equation,
is the reactants and
is products.
Hence, 4 is the subscript in
.
Answer:
From the graph, at t = 5 seconds, the velocity = 50 m/s as shown also in the above table
Please find attached the graph
Explanation:
The initial velocity of the body = m/s
The acceleration of the body = 8 m/s²
The velocity after 5 seconds can be determined graphically and by calculation as follows;
Graphically, we have the data points which can be found by the straight line relation v = u + a×t,
Where ,
a = The slope = 8 m/s²
u = 10 m/s = The y-intercept
Which gives;
v = 10 + 8 × t
The following data can be calculated for various time t;
Time, t Velocity
, v
0, 10
1, 18
2, 26
3, 34
4, 42
5, 50
6, 58
From the graph, at t = 5 seconds, the velocity = 50 m/s as shown also in the above table
Please find attached the graph
By calculation, we have;
v = u + a×t
Where;
v = The final velocity
u = The initial velocity = 10 m/s
a = The acceleration = 8 m/s²
t = The time = 5 seconds
v = 10 + 5× 8 = 50 m/s.
Forces are considered balanced when all of the combined forces lead to no change in the motion of the object. For example, when a book is sitting on a table, the force of gravity is pushing downward and the normal force is pushing upward with exactly the same amount of force. Since they are equal and opposite forces, the book does not move.
Unbalanced forces exist when there are unequal forces acting upon the object, which leads to a change in the state of motion. Unbalanced forces can lead to a change in direction, a change in speed, or both a change in direction and in speed.
