Answer: yeah it is reflection
When all of the objects are lifted to the same height, the object
that has the most mass also has the most potential energy.
If we knew anything about the masses of the objects in this question,
then we could be more specific.
Calculation:
<em>Potential energy = (mass) x (gravity) x (height above the reference level)</em>.
Answer:
0.12
Explanation:
The acceleration due to gravity of a planet with mass M and radius R is given as:
g = (G*M) / R²
Where G is gravitational constant.
The mass of the planet M = 3 times the mass of earth = 3 * 5.972 * 10^24 kg
The radius of the planet R = 5 times the radius of earth = 5 * 6.371 * 10^6 m
Therefore:
g(planet) = (6.67 * 10^(-11) * 3 * 5.972 * 10^24) / (5 * 6.371 * 10^6)²
g(planet) = 1.18 m/s²
Therefore ratio of acceleration due to gravity on the surface of the planet, g(planet) to acceleration due to gravity on the surface of the planet, g(earth) is:
g(planet)/g(earth) = 1.18/9.8 = 0.12
I think the correct answer from the choices listed above is the first option. The statement that best accounts for these different opinions would be that <span>scientists propose contradictory ideas to include all possibilities. Hope this answers the question. Have a nice day.</span>
