The force between the planets will not change after doubling the masses of the planets and distance between them.
To find the answer, we need to know about the gravitational force of attraction.
<h3>What's the gravitational force attraction?</h3>
- According to Newton's gravitational law, the force between two objects is directly proportional to the product of their masses and inversely propertional to the square of the distance between them.
- Mathematically, Gravitational force= GMm/r². G is the gravitational constant.
<h3>What is the gravitational force between two planets when their masses and distance between them are doubled?</h3>
- Then masses are 2M and 2m. Distance is 2r.
- So gravitational force= G×2M×2m/(2r)²
= GMm/r²
Thus, we can conclude that the gravitational force will not change of the masses are doubled and the separation is also doubled between the planets.

Answer:
Say the full question I can't understand what it is
Answer:
3
Explanation:
From the question given above, the following data were obtained:
Length (L) = 3 m
Height (H) = 1 m
Mechanical advantage (MA) =.?
The ideal mechanical advantage for the system can be obtained as follow:
MA = L/H
MA = 3/1
MA = 3
Therefore, the ideal mechanical advantage for the system is 3
<span>When T = room temperature
L = 1.0000m+2.4×10^-5m/°C*0°C = 1.0000m+0=1.0000m
change in the length = l2-l1 = (1.0000m+2.4×10^-5m/°C*T2)-(1.0000m+2.4×10^-5m/°C*T1) = 1.0000m+2.4×10^-5m/°CT2-1.0000m-2.4×10^-5m/°CT1=2.4×10^-5m/°CT2-2.4×10^-5m/°CT1=2.4×10^-5m/°C(T2-T1)
So we don’t need at all the 1.0000m data, we just need T2-T1, which is the difference between room temperature and the current temperature, which is 13.6°C.
change in the length = 2.4×10^-5m/°C*13.6°C = 3.264*10^-4m = 0.3264 mm = 326.4 micrometers</span>
That's the so-called 'solar wind'.
