Answer:
a. The temperature and precipitation will both differ.
Answer:
You determine the net force of an object by adding up all of the individual forces.
Explanation:
If N is the number of forces acting on the body, the net force formula is:
= + + ....+
Where , , and as forces acting on a body.
When a body is at rest, the net force formula is given by
Fa = Applied force and
Fg = Gravitational force.
<u>Example:</u>
A truck is standing still and a force of 70 N is applied on it. If the frictional force is 20 N, then what will be the net force?
Solution:
Given
Applied force Fa = 70 N
Frictional force Ff = 20 N
The net force formula is given by
FNet = Fa + Ff
FNet = 70 + (-20)
FNet = 50 N
Therefore, the net force is 50 N
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:
182.156g
Explanation:
grams = 49/.269 = 182.156g needed
They are called the noble gasesbecause they are very unreactive. The highest occupied energy levels (outermost shells) of their atoms are full: helium atoms have two electrons in their outer energy level. atoms of the other noble gases have eight electrons in their outer energy level.
