Final answer:
The correct second option during the rescue sequence cannot be definitively determined without additional context. Depending on the situation, this could involve contacting rescue services, deploying a lifeboat, signaling for help, or providing first aid.
Step-by-step explanation:
The question refers to sequence of actions in a rescue situation. It is not possible to determine the correct second option without additional context as the sequence might vary depending on the situation. However, if we consider standard rescue protocols, common sense, and the scenarios described:
- Contact the coast guard is often a priority in maritime emergencies, but it may not always be the second step if immediate action is needed on site.
- Deploy a lifeboat could be the second step if there are people in water and the situation permits.
- Signal for help can be an initial step but might also follow attempts to deal with the emergency directly.
- Provide first aid might be the second step if there are injuries that need to be stabilized immediately.
The misconception that drowning people always shout and wave for help is dangerous because victims may actually be unable to vocalize or make noticeable movements. Therefore, awareness and close monitoring of people in the water are crucial.
Using the provided narrative as a hypothetical context, the captain calling for the swimmer to come to the boat suggests a rescue scenario where signaling for help has already occurred or assistance is at hand, hence 'Deploy a lifeboat' or 'Provide first aid' may be viable options for the next steps.
In the physics problem where a life preserver is thrown from a helicopter, the scenario implies that aid is already being provided, which again could point towards the second step being either deploying a means to assist or provide first aid once the person is reached.
