Neutrons
Explanation:
Atoms of the same elements are called isotopes. They differ from other atoms in the number of neutrons they posses. They share the same chemical properties but only differ with regards to their mass number.
- Isotopy is a phenomenon whereby an atom of an element exist in more than one form but they have the same atomic number.
- Atoms of such element only differ in the number of neutrons they contain.
- Since the mass number of an atom is the sum of protons and neutrons, they differ in this number too
- Isotopes have the same chemical properties.

Answer: Period T = 4.44secs
Explanation: see attachment
Answer:
three times the original diameter
Explanation:
From the wire's resistance formula, we can calculate the relation between the diameter of the wire and its length:
Here, d is the wire's diameter, 
is the electrical resistivity of the material and R is the resistance of the wire. We have 
The mass of moon is 1/100 times and its radius 1/4 times that of earth as a result the gravitational attraction on the moon is about one sixth when compared to earth.
Becomes older
Explanation:
As sea floor spreading occurs at divergent margins, the oceanic plate becomes older. Younger plate margin are the closest to the margin whereas the older plates bushes backward away from the spreading centers.
- The idea that the sea floor spreads was postulated by Harry Hess shortly after the second world war around the 1960's.
- At divergent margins new crust materials from the mantle are brought to the surface.
- They crystallize and settle at the flanks of plate margins.
- Older ones are pushed backward away from the margin into far away subduction zones.
