I think the right one is b.
If you mean which of the two is denser, then you want the oceanic crust.
The scientist who discovered the first real evidence of the big bang was EDWIN HUBBLE.
Astronomer Edwin Hubble was an American astrophysicist. He contributed in so many ways to humanity during his lifetime. One of his contribution is that, his observation showed the existence of galaxies that are far beyond the milky way; these galaxies were moving away from one another. This observation serves as a concrete evidence for the big bang theory, which explain the origin of the universe.
The power used by Alex to drag the log across the yard is determined as 2,656 W.
<h3>Mass of the log</h3>
The mass of the log is calculated as follows;
W = mg
m = W/g
m = (400)/9.8
m = 40.82 kg
<h3>Velocity of the log</h3>
K.E = ¹/₂mv²
v² = 2K.E/m
v² = (2 x 900)/(40.82)
v² = 44.096
v = 6.64 m/s
<h3>Power used by Alex</h3>
P = Fv
P = 400 x 6.64
P = 2,656 W
