Answer:
P(final) is 2.4 times P(initial).
Explanation:
Here we can assume that the cylinder did not break and it's volume and number of moles of gas present in the cylinder remains constant.
Given the temperature increases by a factor of 2.4. Let us assume that the initial temperature be
and the final temperature be
.
Given that 
Now we know the ideal gas equation is PV=nRT
here V=constant , n=constant , R=gas constant(which is constant).





Explanation:
Let us assume that piece 1 is
is facing west side. And, piece 2 is
facing south side.
Let
= m and
= 2m. Hence,


= 10.5 m/s


= 10.5 m/s

= 
= 14.84 m/s
or, = 15 m/s
Hence, the speed of the third piece is 15 m/s.
Now, we will find the angle as follows.

= 
= 
= 
Therefore, the direction of the third piece (degrees north of east) is north of east.
I have no clue sorry maybe try applying the answers and questions then I'll answer for u
