Answer :
Answer:
When you use desu"ne" you are saying something that( you think) someone you talk with agrees with what you say.
ex.)いい おてんき ですね。 (He is awake and knows it's fine.)
When you use desu"yo" you are giving new information to someone you talk to.
ex.) いい おてんき ですよ。（He’s still in bed and doesn't know today's weather.)
Explanation:
Desu-ne is used in a dialogue when you wish to hear out the other person you are talking to. It is like an invitation for the other to talk. is that right? Desu Yo is more assertive.
