Answer:
Hemoglobin is a protein (because it's a molecule that's not a living part of the cell but aids in cell processes).
Answer:
Δ P = 13.24 Pa
Explanation:
Given that
Density of oil ,ρ₁ = 9 x 10² kg/m³
We know that density for mercury ,ρ₂ = 13.6 x 10³ kg/m³
The change in the height of column ,Δh = 1.5 mm
The pressure given as
P = ρ g h
Change in the pressure
Δ P = ρ₁ g Δh
Now by putting the values
Δ P = 9 x 10² x 9.81 x 1.5 x 10⁻³ Pa
Δ P = 13.24 Pa
Therefor the change in the pressure will be 13.24 Pa.
Answer:
4°C
Explanation:
Water is densest at 4°C. Since dense water sinks, the bottom of the lake will be 4°C.
<h3>Answer: 2 seconds</h3>
This problem is equivalent to kicking the ball 8 m/s and it rolls to a point 16 meters away, and everything is on a flat ground (with no cliff). This is because the horizontal component of the velocity does not get affected by how tall the cliff is and the force of gravity. Note how the height of the cliff isn't even mentioned. So that's a clue that we can ignore it.
If x is the number of seconds, then 8x is the distance in meters it travels. So we have 8x = 16 solve to x = 2. The ball travels for 2 seconds before reaching its target.
Is that the question? What? I'm so confused is this some sort of riddle or something
