Relative time is the physical subdivision of the rocks found in the Earth's geology and the time and order of events they represent. Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired
Explanation:
Answer:
(a) Moon has smaller diameter and lower density than earth
Explanation:
Moon has smaller diameter than earth earth has a diameter of 12742 km whereas moon has a diameter of 3474.21 km
So for density density is given by 
From the relation we can see that density is dependent on mass and volume directly proportional to mass and inversely proportional to diameter
But in case of earth and moon mass is more dominating than volume so density is less for moon than earth

Explanation:
CASE: A wire is moved through the field of a magnet
As the wire is moved through the field of a magnetic the magnetic flux through the circuit loop changes,; therefore current is induced.
CASE: A magnet is held close to a wire
There needs to be relative motion between the wire and the magnet for the current to be induced; therefore, simply holding a magnet close to a wire will not induce current in the circuit.
CASE: A magnet is moved into a coil of wire
As the magnet is moved into a coil of wire, the magnetic flux through the coil changes, and therefore, the current is induced.
CASE: A magnet is moved out of coil of wire
Moving a magnet out of coil of wire also changes the magnetic flux through the coil; therefore, the current is induced.
CASE: A magnet rests in coil of wire
There needs to be relative motion between the coil of wire and the magnet for the current to be induced; therefore, a magnet resting in the coil of wire will no induce any current in the coil.
