Answer:
The resulting liquid at the top is the plasma.
Explanation:
This question seeks to compare the difference between the methods of preparation of plasma and that of serum.
To obtain serum from a blood sample, the blood sample is collected in a plain bottle (usually red capped) and the blot is allowed to clot by leaving it standing/alone for about 15 - 20 minutes after collection. This clotted blood is then centrifugated at 2000 - 3000 revolution per minutes (rpm) for 10 minutes. The liquid at the top after centrifugation here is the serum.
In preparing plasma, the blood sample is collected in a bottle that has anticoagulant like the EDTA bottle (which contains an anticoagulant called EDTA) and then inverted slightly about 7 times to allow the EDTA mix with the blood. This blood sample is then centrifugated at 2000 - 3000 for 15 mins. <u>The resulting liquid at the top is the plasma.</u>
1.5*9.8*1.2
since the formula is force * distance.
1.2 is the distance. the force is gravity on the object (1.5*9.8)
The answer is 17.64 J . (18 J with sig figs)
A single slit with a width of 2019 * 109 m creates its initial minimal for 624 nm light at an angle of 18°.
How does diffraction work?
Waves spreading outward around obstructions are known as diffraction. Diffraction happens with sound, electromagnetic radiation like light, X-rays, and gamma rays, as well as with incredibly minuscule moving particles like atoms, neutrons, and electrons that exhibit wavelike qualities. Diffraction prevents the creation of sharp shadows as one of its effects. In order to spread out and illuminate regions at which a shadow is anticipated, light must be bent around corners, which is known as diffraction.
Calculation:
Provided for a single slit, m=1
λ = 624 *10⁻⁹
sinθ = sin 18⁰
Therefore,
asinθ=mλ
a =
⇒a = 2019 *10⁻⁹ m
Therefore the width of a single slit is 2019 *10⁻⁹ m.

The hydrogen bonds that form between water molecules account for some of the essential and unique properties of water. The attraction created by hydrogen bonds keepswater liquid over a wider range of temperature than is found for any other molecule its size.
