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,
Answer: Two celestial objects are in space: one with a mass of 8.22 x 109 kg and one with a mass of 1.38 x 108 kg. If they are separated by a distance of 1.43 km, then, the magnitude of the force of attraction (in newtons) between the objects will be 52.9kN
Explanation: To find the answer we need to know more about the Newton's law of gravitation.
<h3>What is Newton's law of gravitation?</h3>
- Gravitation is the force of attraction between any two bodies.
- Every body in the universe attracts every other body with a force.
- This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between these two masses.
- Mathematically we can expressed it as,
<h3>How to solve the problem?</h3>
- Here, we have given with the data's,
- Thus, the force of attraction between these two bodies will be,
Thus, if two celestial objects are in space: one with a mass of 8.22 x 109 kg and one with a mass of 1.38 x 108 kg and, If they are separated by a distance of 1.43 km, then, the magnitude of the force of attraction (in newtons) between the objects will be 52.9kN.
