Answer:
k = 1,250 N/m
Explanation:
Use the formula F=kx, with F=5N and x=0.04m
Then the spring constant (k) is 5/0.04
The dimension of force, F is ML/T².
<h3>What is force?</h3>
Force is a push o push agent which causes a change in the state of rest or motion of an object.
From a fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass.
Mathematically; acceleration ∝ F/m
F = ma
dimension of Mass = M
dimension of acceleration = L/T²
dimension of force, F = ML/T²
In conclusion, the dimension of force is obtained from the dimensions of mass and acceleration.

Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:

<h3>What is a chemical formula?</h3>
A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.
From the chemical formula;
We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;
Carbon = 1 atom
Hydrogen = 1 atom
Chlorine = 3 atoms
So, in 5 molecules of the compound;
Carbon = 1 x 5 = 5 atoms
Hydrogen = 1 x 5 = atoms
Chlorine = 3 x 5 atoms = 15 atoms
In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of .
