Each pure element has certain chemical properties, a specific atomic arrangement and a specific crystalline structure that distinguish this pure element from other elements.
On the other hand, the mass of any substance/object depends on the AMOUNT or the QUANTITY of matter in the object.
Based on the above, three objects made of pure iron would have:
Different masses
Same arrangement of atoms
Same crystal structure
Same chemical properties
Comparing the above to the given choices, we would find that the best choice is:
b. They have the same chemical properties

Answer:
The transmission of energy is one thing that is carried out by all kinds of waves. They transmit energy from one point, known as the source, to another point.
For instance, in electromagnetic waves, energy is transmitted as a result of vibrations between the magnetic field and electric field. In mechanical waves, energy is transmitted when the particles in the medium heat up and vibrate. Energy travels through particles in a medium.
Answer:
What is the acceleration of an object moving at a constant speed?
The Meaning of Constant Acceleration
The data table above show an object changing its velocity by 10 m/s in each consecutive second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second.
