<span>1. A cylinder is submerged in water as illustrated in the diagram. Which of the following statements is true?
</span><span>The pressure at D is greater than at B. This is because D is trying to get back to the surface with an amount of pressure. B has less amount of pressure.
</span><span>2. A cylinder is submerged in water as illustrated in the diagram. If the area of the top and the bottom of the cylinder is the same, which of the following statements is true?
</span><span>buoyant force = (force D - force A).
Edit: If you ever notice. When you fill a sink full of water. Put a glass upside down and try forcefully to submerge it under the water it will resist. This is because of the pressure and air. The glass is less dense then water. (Also depends on the glass)</span>
(2) subtracting the atomic number from the atomic mass number, because the mass number is the total number of protons and neutrons in an atom and the atomic number is the number of protons in an atom.
Generally, leucine is hydrophobic in nature and it has a carbon-hydrogen side chain. Therefore, it is not advisable to use an hydrophobic solvent because the leucine zipper would interact with both the opposite alpha helix and the solvent. This will ultimately hinder the dimer creation. Thus, the best solvent which is the least polar in the list is hexane.
The reaction between C2H6 and
Cl2 by addition is C2H4Cl2 or dichloroethane. It must be under the presence of
sunlight because halogen such as chlorine cannot easily react with the sigma
bond of alkane such as ethane.
