If the clock loses 15 minutes every hour, it effectively runs at 45 minutes for every hour that passes. When the slow clock shows 10 AM, 1 hour has passed for that clock, but only 45 minutes have passed in real time. Therefore, if the clock was set correctly at 9 AM, the correct time when the slow clock shows 10 AM will be 9:45 AM.

A clock that gain 30 second every hour will gain how many minutes in a day?
Precision is based on the cycle and not the time on the face. An hour is an hour no matter what the time is on the clock.

Yes, a clock that loses 1 second every hour is more accurate because it consistently maintains the correct time; it would only be off by 24 seconds after a full day. The clock that is consistently 3 seconds slow would accumulate a larger error over time.

Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
