Answer:
The initial volume of the system: <u>V₁ = 53.06 L</u>
Explanation:
Given: heat absorbed by system: q = 50.5 J, Pressure: P = 0.491 atm, Final volume: V₂ = 56.2 L, The change in the internal energy: ΔE = -106.0 J
Initial volume: V₁ = ? L
<u>According to the First Law of Thermodynamics</u>:
ΔE = q - PΔV
⇒ PΔV = q - ΔE = 50.5 J - (-106.0 J) = 156.5 J
As, 1 L∙atm = 101.3 J ⇒ 1 J = (1 ÷ 101.3) L∙atm
⇒ PΔV = 156.5 J = (156.5 ÷ 101.3) L∙atm = 1.54 L∙atm
So,
ΔV = 1.54 L∙atm ÷ P = 1.54 L∙atm ÷ 0.491 atm = 3.14 L
∵ ΔV = V₂ - V₁ = 3.14 L
⇒ V₁ = V₂ - 3.14 L = 56.2 L - 3.14 L = <u>53.06 L</u>
<u>Therefore, the initial volume of the system: V₁ = 53.06 L</u>
Answer:
Option C (nuclear binding energy) is the appropriate choice.
Explanation:
- At either the nuclear scale, the nuclear binding energy seems to be the energy needed to remove and replace a structure of the atom itself into the characterize elements (to counteract the intense nuclear arsenal).
- Nuclear warheads (bargaining power) bind everything together neutrons as well as protons within an elementary particle.
Some other options in question aren't relevant to the particular instance. So that the option preceding will also be the right one.
The phospholipid head is hydrophilic which means it has an affinity for water. And it is true.
<h3>What is phospholipid , its component and how come it is hydrophilic?</h3>
- Phospholipid contains of a head and a tail , the head part of phospholipid consist of phosphate group and for further clarification the tail part of phospholipid consist of fatty acids.
- As we know already phosphate group that is OH- is negatively charged which clearly which its head is going to be polar .
- Since its polar , its hydrophilic. There is a specific function performed by phosphate group that cannot be filled by other compound present simultaneously.
- Phosphate group grabs a role to provide space to other compounds too.

Answer: The fault is younger than the layers of rock, according to the law of crosscutting.
Explanation:
Then Law of Crosscutting which was described by James Hutton explains that whenever a fault is seen on a rock, the fault will always be younger than the rock it is one.
This makes sense because if there was no rock in the first place, the fault would not have cut through it. But because there was a rock and an object exacted a force in order to move through the rock, the fault appeared showing that the rock came first, then came the fault.
