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
They led the household was the role of women as industry increased. So C
Answer:
Moon and Earth both exert equal force on each other
Explanation:
As we know by the universal law of gravitation the force of gravitation is given by the formula
This is the mutual gravitational force on Earth and Moon by which they attract each other.
So here the force of attraction due to Earth on Moon as well as the Force due to Moon on Earth both will be same in magnitude and opposite in direction.
So here both forces is given as
Moon and Earth both exert equal force on each other
