How long is the penalty for a second unsportsmanlike conduct penalty assessed?

In the context of NFHS football rules, a second unsportsmanlike conduct penalty results in an automatic ejection of the player from the game. This rule is in place to maintain sportsmanship and player conduct on the field. The rationale behind this is that repeated unsportsmanlike behavior indicates a disregard for the game's integrity, and by enforcing ejection, officials deter such actions and promote a more respectful environment for all participants.

The other options, while they may seem plausible, do not accurately reflect the outcomes prescribed by the NFHS rules. A 5-minute suspension, a 15-yard penalty, or a 10-year ban from the game do not apply to the situation described in the question regarding a second instance of unsportsmanlike conduct. Instead, the emphasis is on the immediate consequence of ejection, ensuring that players understand the seriousness of their behavior on the field.
