Answer:To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Explanation:
Answer:
Resistance can increase relative to Temperature, Nature of Material, Length of Conductor or wire.,and Cross-section area.
Explanation:
The electric force between two charged particles can be increased by decreasing the distance between the two particles.

Answer:
work =p×v =3.27×10^5×1.5×10^-3 =490.5 joule
efficiency =w/q in
:. qin= w/efficiency =490.5/0.225=2180 joule
qout =q in - work =1689.5 joule
q out is work given as heat
