Answer:
The column number tells us the amount of valence electron the element has
Answer:
10.2 kg
Explanation:
Assuming the object is on Earth:
w = mg
m = w / g = 100 / 9.81 = 10.2kg
Mechanical weathering is actually breaking down of rocks into smaller pieces by natural forces. Any weathering processes that can cause the physical breakdown of rocks without any type of change in the chemical composition of rocks, called mechanical weathering.
So, looking at each of the definitions in the options, we can easily choose:
1. Hydration : It's a process of absorbing water by substance.
2. Carbonation: It's a process of Carbon Dioxide dissolving in liquid (mostly water).
3. Oxidation : It's a process of oxygen reacting with some element.
4. <span>Exfoliation: It's a process where the rocks erodes by peeling off in sheets or layer by layer rather than grain by grain.
As you can see the last one </span><span>Exfoliation matches with the definition of mechanical weathering. It's one of its types.</span>
Answer:
Explanation:
Given that,
1.00 in = 2.54 cm
We know that,
1 feet = 12 inches
We calculate the number
We need to converted 
to 
The number required is
Hence, This is the required solution.
If the speed of an object does NOT change, the object is traveling at uniform speed.
