Answer:
0.000311 m³
Explanation:
The formula that connect volume, mass and density is given below
D = m/v ...................... Equation 1
Where D = Density of the gold, m = mass of the gold, v = volume of the gold.
make v the subject of the equation
v = m/D .................. Equation 2
Given: m = 6 kg,
Note the density of pure gold = 19300 kg/m².
Substitute into equation 2
v = 6/19300
v = 0.000311 m³
Hence the volume that will verify that it's a pure gold = 0.000311 m³
Explanation:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault labeled "E" cuts through all three sedimentary rock layers (A, B,and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen and known of.
The nitrogen fixation is the process of conversion of nitrogen gas into a usable form.
Answer: Option 3
<u>Explanation:
</u>
The nitrogen fixation is the process where the nitrogen gas present in air gets trapped and converted into ammonia or other nitrogenous compounds. This is the first step of nitrogen cycle.
The atmospheric nitrogen will get absorb in soil and gets converted to either ammonia which acts as nutrition for plants or other nitrogen related compounds which acts as fertilizers.
So, the nitrogen which get converted to usable stable form of nitrogen compounds can be used by plants, microorganisms and other organisms in the ecosystem.
Friction made it difficult because an object in motion may not always stay in motion due to the friction caused by its movement. For instance, if you roll a ball down a straight platform, it will not go on forever. The friction of the platform and the ball with eventually slow it down and stop it.
