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:
42$
Step-by-step explanation:
So there's an easy way to know this.
100%--$70
60%--x
<em>cross multiply </em>
100x=4200
÷100 ÷100
______________
x=42
So he saved 42$. Hope this helps :D
Answer:
Step-by-step explanation:
- Let's assume that it is rational , so this number can be represented as
<h3>
-Since the denominator is not a natural number then the 1/√2 is respectively an irrational number</h3>
Answer:
Percentage of x free throws =
Step-by-step explanation:
We are given the following in question:
Total number of throws = 50
Number of free throws made = 42
Percentage of x free throws made is given by:
Putting x = 42, we get,
Percentage of free throws made =
Thus, Liam made 84% free throws this morning.
45x5 = 225 minutes a week
225 x 12 = 2700 minutes in 12 weeks
2700 / 60 = 45 hours
1800 / 45 = 40 laps per hour
answer: average 40 laps per hour
