<u>Answer</u>
The distance must be one-third the original distance.
<u>Explanation</u>
Gravitational force is the force of attraction between two bodies of given masses. It is calculated by the formula;
Gravitational force = Gm₁m₂/r²
This means, for the gravitational force to remain unchanged, both numerator and denominator has to change by equal value.
The numerator changed by (1/3×1/3 = 1/9).
So, r² must change by the same value which is 1/9.
If r² ⇒ 1/9, then
r ⇒ √1/9
⇒ 1/3
So, this means, for the gravitational force to remain as 200, The distance must be one-third the original distance.
Answer:
Barium - Ba
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element.
Symbol: Ba
Atomic mass: 137.327 u
Electron configuration: [Xe] 6s2
Atomic number: 56
Van der Waals radius: 268 pm
Discoverers: Humphry Davy, Carl Wilhelm Scheele
Answer:
0.8 L
Explanation:
Ideal gas law: PV = nRT
At constant mass and pressure, nR/P = nR/P.
Therefore, V/T = V/T. (Remember to use absolute temperature.)
V/T = V/T
1 L / (37 + 273 K) = V / (-25 + 273 K)
V = 0.8 L
