A.) 你昨天给我打电话吗？Did you call me yesterday?——你昨天给我打电话了吗？“了”shows that it happened in the past.it is used in the past tense.if you want to know if something will happen,you can say"你明天给我打电话吗？”will you call me tomorrow.——don't forget “了”when you talk about something that has already happened.

A.) 对不住, 在很忙的。I'm sorry, I was very busy.——对不起（对不住also right),当时很忙的。（i was very busy at that time)"在“is used when you are talking something you are doing.  eg:"我在读书”（i was reading),or "我在睡觉“（i was sleeping.)...but "忙”is an adjective,so "在“is not needed.  eg:"我很生气”（i was very angry), or "我很伤心“(i was very sad.)
