Let the forces on two pillars are N1 and N2
so we will have force balance equation as


also by torque balance we will have
![N_2\times L = 40000 ]times \frac{L}{2} + 19600 \times 8](https://tex.z-dn.net/?f=N_2%5Ctimes%20L%20%3D%2040000%20%5Dtimes%20%5Cfrac%7BL%7D%7B2%7D%20%2B%2019600%20%5Ctimes%208)
here we know that
L = 20 m



The argon molecules become solid when the temperature decrease from 20C to -190 C.
<h3>What changes occur in argon?</h3>
The changes in arrangement and movement of the particles of the argon occurs as the temperature of the air decreased because the argon gas begins to freeze. The freezing point of argon is -189 Celsius so when the temperature decrease from 20C to -190 C, the argon molecules becomes solid.
So we can conclude that the argon molecules become solid when the temperature decrease from 20C to -190 C.

Answer:
Explanation:
Formula to calculate the distance between two points
and
is,
d = 
Therefore, length of CD having coordinates C(3,1) and D(3, 3),
CD = 
= 2 units
Formula to find the midpoint of CD is,
M = 
= 
= (3, 2)
Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.
Electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.
<h3>What is electricity?</h3>
Electricity is the movement or flow of negatively charged electrons through a suitable conductor where a charge is applied.
Moreover, magnetism is a natural phenomenon caused by the generation/movement of electric charges.
In conclusion, electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.

Since force is mass*acceleration,
F = 70kg * 9.8 m/s
