It would mean that only one side of earth would be light and the other dark all the time also we would only see the sun on one side and on the other we see the moon
First one, for instance they become conductors or insulators depending on the temperature!
The force of gravity between two objects is:
F = G*m1*m2/r^2
So, it is dependent of the two masses and the distance between their centers of mass.
Answer:
Explanation:
Given
--- initial volume
--- initial temperature
--- final temperature
--- coefficient of thermal expansion:
Required
The change in volume
To do this, we make use of cubic expansivity formula
So, we have:
The volume will expand by
