Answer:
No
Explanation:
When a substance changes its state , there will not be any change in the mass of substance . For example , if we change 100 grams of water (liquid) to ice(solid) , the mass of ice will be same i.e., 100 grams . This shows there is no change in the mass even if a substance changes its state.

5g/cm³
it is not iron.
Explanation:
Given parameters:
Density of iron = 7.874g/cm³
Mass of metal = 2000g
Volume of metal = 400cm³
Unknown:
Density of bar = ?
Is it iron = ?
Solution:
The density of a substance is its mass per unit area. Every substance have an intensive density value that typifies them all.
The density of water and other substances are the same if they maintain their level of pureness.
Density = 
Density of metal bar = 
= 5g/cm³
Since this value is not the same as the given density of iron, it is not iron.

The x-component of a vector are < 106.6, 43.07 >
Depending on the angle we are provided, the x-component of a vector can either be cos or sin. Cos always corresponds to the right triangle's side that contacts the specified angle.
If a vector v with magnitude ||v|| makes an angle θ with the positive x-axis then,
v = ||v|| cos θi + ||v|| sin θj
= < ||v|| cos θ , ||v|| sin θ >
Magnitude p = 115 km
Angle = 22°
p = ||p|| < cos θ, sin θ >
p = 115 < cos 22°, sin 22° >
p = 115 < 0.927, 0.3746 >
p = < 106.6, 43.07 >
Therefore, the x-component of a vector are < 106.6, 43.07 >
