<h2>Equation of state of an ideal gas</h2>
<em>The </em><em>ideal gas law is derived</em><em> from the ga</em><em>s laws of Boyle, Charles, Gay Lussac and General.</em>
To solve this exercise, we obtain the data of the exercise:
- V₁ = 52 Lt
- P₁ = 1,2 atm
- P₂ = 0.75 atm
- V₂ = ¿?
<em>The general formula of the </em><em>Equations of state of an ideal gas is:</em>
<h3>P₁V₁=P₂V₂, Where</h3>
- P₁ = Initial pressure
- V₁ = Initial volume
- P₂ = End Pressure
- V₂ = Final Volume
We clear the formula, since it is the value that we must calculate.
<h3>
V₂ = P₁V₁ / P₂</h3>
To solve, we substitute our data in the formula; and we solve
<h3>
V₂ = (1,2 atm)·(52 Lt) / 0.75 atm</h3><h3>
V₂ = 0.832 Lt</h3>
Answer:<em> The </em><em>volume that the gas will occupy</em><em> if the pressure increases to 0.75 atm is </em><em>0.832 lt.</em>

A force is the push or pull acting on an object as a result of its interaction with another object. Here the net force acting on the box is 297 N
From the question
Given that,
Mass of the box ,m = 102 kg
Acceleration of the box ,a = 2.5 m/s²
Frictional force acting between the box and the floor ,<em>f =</em> 42 N
Here we have to find the net force acting on the body, F = ?
By Newton's second law of motion,
∑F = ma,
where, F is the net force
m is the mass of the body
a is the acceleration of the moving body
If the body is considered moving in the x-direction then,
F-<em>f = ma</em>
<em>F - 42 = 102 x 2.5</em>
<em> = 255</em>
<em>F = 255 + 42 = 297 N </em>

Answer: A. land-based</h2>
Explanation:
An artificial satellite is one that is launched into space to orbit the Earth (or another body of the solar system) for various purposes.
In this sense, the characteristics of an artificial satellite will depend on its purpose and functionality. From there we can list: meteorological satellites (for weather) , telecommunications satellites, remote sensing satellites, global positioning systems satellites, environmental satellites, research satellites, among others.
In addition, their orbits can be classified according to their height and inclination, depending on the use they have.
On the other hand, one of the main conditions for a satellite to be considered as such is that it must be kept orbiting. This means, it must not touch land during its useful life, even if it remains in constant contact with its earth based control stations.
Therefore,<u> a land-based is not a type of satellite.</u>
The Coulomb’s law is expressed mathematically as:
F = k * q1 * q2 / d^2
Where,
F = force of attraction between 2 particles = 2.0 N
<span> k = Coulomb’s
constant = 8.988 * 10^9 N m^2 / C^2</span>
q = charge of the particle
d = distance between the 2 particles = 1.35 m
Since the two coins have identical charges therefore q1 =
q2 =q
F = k* q^2 / d^2
2.0 N = (8.988 * 10^9 N m^2 / C^2) * q^2 / (1.35 m)^2
q =
2.01 * 10^-5 C
<span>Therefore each coins have charges equivalent to 2.01 *
10^-5 C.</span>
