Answer:it should be Newton’s second law
Explanation: lmk if I’m wrong
Type of conductors determines rate of flow of current
Answer:
The change in volume is 
Solution:
As per the question:
Coefficient of linear expansion of Copper, 
Initial Temperature, T =
= 273 K
Final Temperature, T' =
= 273 + 100 = 373 K
Now,
Initial Volume of the block, V = 



where
V' = Final volume


The planets have (their) moons. So the answer would be planets.
