Answer:
These are the two statements with scientific facts that explain the described phenomenon
<span>
Gravitation between two objects increases when the distance between them decreases.</span>
When the mass of an object increases, its gravitational pull also increases.
Justification:
Those two facts are represented in the Universal Law of Gravity discovered by the scientific Sir Isaac Newton (1642 to 1727) and published in his book <span>Philosophiae naturalis principia mathematica.</span>
That law is represented by the equation:
F = G × m₁ × m₂ / d²
The product of the two masses on the numerator accounts for the fact that the gravitational force is directly proportional to the product of the masses, which is that as the masses increase the attraction also increase.
The term d² (square of the distance that separates the objects) in the denominator accounts for the fact that the gravitational force is inversely proportional to the square of the distance; that is as the separation of the objects increase the gravitational force decrease.
Answer:
A.
B.
C.
D.
Explanation:
Given:
- no. of moles of oxygen in the cylinder,
- initial pressure in the cylinder,
- initial temperature of the gas in the cylinder,
<em>According to the question the final volume becomes twice of the initial volume.</em>
<u>Using ideal gas law:</u>
A.
<u>Work done by the gas during the initial isobaric expansion:</u>
C.
<u>we have the specific heat capacity of oxygen at constant pressure as:</u>
Now we apply Charles Law:
<u>Now change in internal energy:</u>
B.
<u>Now heat added to the system:</u>
D.
Since during final cooling the process is isochoric (i.e. the volume does not changes). So,
The first one is B. I think and the second one is A.
It is imperative that the system-grounded conductors remain buried and is denoted as option D.
<h3>What is a Conductor?</h3>
This is referred as a substance which allows electricity and heat to flow through it and examples include metals.
These conductors have to be buried so as to prevent the risk of contact and electrocution of individuals thereby making it a safe method.
