It depends also of what the box is made of
You weigh an object to determine its mass. Weight is directly proportional to mass, and in fact most balances are calibrated in mass units such as kilograms.
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
Put it on a balance and determine its mass.
It is near Earth in size. About 81.5% of Earth's mass.
No, the mass of a planet does not equal the size of that particular planet.
The answer depends on the size of the box!
But you CAN determine the size of the planets: in diameter, overall mass, and in density.
Density = mass/volume. 12.9g/15cm3 = 0.89g/cm3.
Once you know their distances, you can determine basic properties of the planets such as mass, size, you can determine its linear diameter.
by size,volume and gravity
You can determine the circumference of a reduction gear box by multiplying its diameter by pi. This is because its outer portion is a circle.
the stars amount of mass
Mass and Charge
By size I think you mean the volume. And no, you also need the density of the object. Which tells you how much a given size weighs.
The mass of 14 books in a box would depend on the individual weight of each book and the weight of the box itself. Without specific weights to provide an accurate calculation, we would need more information to determine the total mass.
determining its mass from its gravitational pull on a spacecraft, satellite, or planet.
Mass and distance. Greater the mass the more force the closer the distance the more force as well
