Answer:
According to our present theory of solar system formation, why were solid planetesimals able to grow larger in the outer solar system than in the inner solar system? Because only metal and rock could condense in the inner solar system, while ice also condensed in the outer solar system.
Explanation:
Answer:
Explanation:
The total charge in the disks
must be conserved before and after bringing them together.
Lets equate the sum of the initial charge with the sum of the final for the disk:
So, the initial charges must sum +17 μC.
Now, as there are no charges over +17 μC, this means that both charges must be positive.
As the only positive charges are 
and 
, this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:
When you put ice in the freezer, the water expands when in gets cold.
the sidewalks have cracks in them to make room for the expansion and contraction when it heats up and cools down.
as you drive a car, the heat from combustion causes metal to expand. when you turn the car off, the metal cools down and contracts
