Answer:
The final pressure of the gas when its temperature returns to its initial value 
Pa.
Step-by-step explanation:
Given : An ideal gas is confined within a closed cylinder at a pressure of 
Pa by a piston. The piston moves until the volume of the gas is reduced to one-ninth of the initial volume.
To find : What is the final pressure of the gas when its temperature returns to its initial value?
Solution :
Since the temperature is constant
.
The relation between P and V is given by,
....(1)
The piston moves until the volume of the gas is reduced to one-ninth of the initial volume i.e. 
or 
Substitute in equation (1),
The final pressure of the gas when its temperature returns to its initial value Pa.
Answer:
b. 98
Step-by-step explanation:
May and June:
May: 223 Dinztop sales
June: 148 Dinztop sales.
So
In June, it sold 0.6637 = 66.37% the amount of computers sold in May.
How many Dinztop computers will be sold in July?
Because of the same percent rate, 0.6637 = 66.37% of the amoutns sold in June.
0.6637*148 = 98
The correct answer is given by option b.
Answer:
B. I and III
Step-by-step explanation:
I and III both have the same data:
March, 73
April 74
May 78
June 84
July 75
II has different data
March 71
April 72
May 85
June 90
July 60
Since I and III have the exact same data, choice B is the best answer
Hope this helps! :)
t N.
In the figure shown below
Answer:
A horizontal line segment M K intersects with line segment J L at their midpoint N.
∠J N M =(5x+2)°
∠ LN M=3( x+ 14)°
So, ∠J N M + ∠ LN M =180°[ These two angles form linear pair.Angles forming linear pair are supplementary.]
⇒5 x+ 2+ 3 (x+ 14) =180 [ By Substitution]
⇒ 5 x+2 +3 x+42°= 180°
⇒ 8 x=180°-44°
⇒8 x= 136°
⇒x= 136°÷8
⇒x=17°
So, ∠J N M =5×17 +2=87°
∠ LN M= 3×(17 +14)=3×31=93
∠J N M =∠K N L [Vertically opposite angles]
∠K N L=87°
Answer:
The three correct answers are B "The sine function increases on (0°, 90°) and (270°, 360°)." , E "Both the cosine and sine functions have a maximum value of 1.", and F "Both the cosine and sine functions are periodic."
