Answer:
I think it should be Carbon.
Answer: X: High and Y: High
Explanation: When comparing plasma with solids it is seen that solids are more denser than plasma and has less kinetic energy as compared to plasma.
So among the difference plasma will have high kinetic energy and solids will have high density in comparison with each other.
Answer: It minimizes fossil fuels and is a pollution-free mode of transport. Bokes reduce the need to build, servie and dispose cars.
Hope this helps you out.
The mass is
Explanation:
First, we need to find the volume of the cube.
v = lwh
v = (4)(4)(4)
v = 64 cubic cm
Now, since we know the volume and the density, we can figure out the mass.
The formula is mass = volume x density
Mass = 64 x 2.7
Mass = 172.8 g.
Therefore, the mass is 172.8 grams.
