Answer:
(a) 
(b) 
Explanation:
Hello.
(a) In this case, since the initial volume is 18.5 dm³ and the final volume is 21 dm³ (18.5 +2.5), we can compute the work at constant pressure as shown below:
Which is negative as it expands against the given pressure.
(b) Moreover, of the process is carried out reversibly, the pressure can change, therefore, we need to compute the work via:
Whereas the moles are computed from the given mass of argon:
Thus, the work is:
Regards.
Answer:
Explanation:
According to the statement, three confused sleigh dogs are trying to pull a sled across the Alaskan snow.
Forces in same direction gets added , so 35N + 42N=77N and the Net Force is 77N -53N as it is acting in opposite direction.
Net force is 25N in east to the maximum without any hassle.

Answer:
correct option is B
the absolute pressure will be less than 2p
Explanation:
given data
absolute pressure = p
depth = twice
to find out
what is correct option
solution
we know here that p absolute pressure so we consider atmospheric pressure p1
so we can say at some depth h pressure will be
pressure p = p1 + ρ g h
so if depth is double
pressure will be
2p = 2p1 +2 (ρ g h )
so
2p - p1 = p1 + 2 (ρ g h )
so correct option is B
the absolute pressure will be less than 2p
