Answer:
a)P/Po=0.263
b)γ=1.33 So gas is triatomic
c)
Explanation:
a)
initial pressure = Po
Initial volume = Vo
Final volume = 3.8 Vo
Lets take final pressure is P
we know that for free expansion process
PV= Constant
Po x Vo = P x 3.8 Vo
P=0.263 Po
So
P/Po=0.263
b)
Now gas is compressed in adiabatic manner
Final pressure = 1.56 Po
=1.56 Po
We know that for adiabatic process
γ=1.33 So gas is triatomic
c)
We know that average kinetic energy given as
\
Answer:
contains many young stars
Explanation:
Irregular galaxies have <em>no definite shape</em>, which means that the first option is incorrect. They are definitely not round.
However,<u> they contain many young stars because the degree of star formation is fast.</u> They also contain old stars. Thus, the second choice is correct.
The "spiral galaxy" is the type of galaxy that has arms that extend from the center. These arms look "spiral," which influenced its name. This makes the last choice incorrect.
They are actually <u>smaller than the other types of galaxies.</u> This makes them <em>prone to collisions</em>. This makes the last choice incorrect.
Answer:Agoraphobia
Explanation:
Acrophobia is a fear associated with heights i.e. fear of height
while Phobia characterized by intense fear is called Agoraphobia which is a anxiety disorder that can make you feel trapped so "Acrophobia" must be replace with "Agoraphobia" to make the sentence right.
The difference between the distance and the displacement is the speed is a scalar while displacement is a vector.
<h3>What is the distance an the displacement?</h3>
The distance is the difference between two points while the displacement is the difference between two points in a specified direction. Given that speed is a scalar and the displacement is a vector. It follows that we must take the displacement when obtaining the displacement.
Thus, the distance that is covered after one lap is the circumference of the circle = 2πr = 2 * 3.142 * 25 = 31 m Then for 2 laps = 62 m
The displacement is obtained when we take the direction into consideration. Owing to the fact that the runner returns to the starting point each time, the displacement is zero.
