Answer:
![\Delta U = 1640 J](https://tex.z-dn.net/?f=%5CDelta%20U%20%3D%201640%20J)
Explanation:
As we know by first law of thermodynamics that for ideal gas system we have
Heat given = change in internal energy + Work done
so here we will have
Heat given to the system = 2.2 kJ
Q = 2200 J
also we know that work done by the system is given as
![W = 560 J](https://tex.z-dn.net/?f=W%20%3D%20560%20J)
so we have
![\Delta U = Q - W](https://tex.z-dn.net/?f=%5CDelta%20U%20%3D%20Q%20-%20W)
![\Delta U = 2200 - 560](https://tex.z-dn.net/?f=%5CDelta%20U%20%3D%202200%20-%20560)
![\Delta U = 1640 J](https://tex.z-dn.net/?f=%5CDelta%20U%20%3D%201640%20J)

Answer:
D. only briefly while being connected or disconnected.
Explanation:
As we know that transformer works on the principle of mutual inductance
here we know that as per the principle of mutual inductance when flux linked with the primary coil charges then it will induce EMF in secondary coil
So here when AC source is connected with primary coil then it will give output across secondary coil because AC source will have change in flux with time.
Now when we connect DC source across primary coil then it will not induce any EMF across secondary coil because DC source is a constant voltage source in which flux will remain constant always
So here in DC source the EMF will only induce at the time of connection or disconnection when flux will change in it while rest of the time it will give ZERO output
so correct answer will be
D. only briefly while being connected or disconnected.
Answer:
C. Code of ethics
Explanation:
The code of ethics of a company is the document where all the values that the members of the company should live and obbey, they are often guideliness on how to act and beheave and how to treat customers, providers and co-workers. IT also has all of the standards for all managers ethical responsabilities, and ethical responsabilities of the general of the employees of the company.
