Mass

Explanation:

They physical property that is not the same among the four objects is their masses.

Mass is the amount of matter contained in a substance.

Specific heat is the amount of energy needed to raise the temperature of 1g of a substance by 1k.
Since the materials are made of the same metal, they have the same specific heat.
They will also have the same magnetism and electrical conductivity.
These properties are intensive property and do not depend on the amount of matter present.
Mass is an extensive property that depends on the amount of matter present.

Answers:

a) $T_{2}>T_{5}>T_{1}>T_{3}=T_{6}>T_{4}$

b) $a_{4}>a_{6}>a_{1}>a_{3}>a_{5}>a_{2}$

Explanation:

a) Since we are told the satellites circle the space station at constant speed, we can assume they follow a uniform circular motion and their tangential speeds $V$ are given by:
