Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
Answer:
B). Danny.
Explanation:
As per the given description, Danny has the most probable chances of success as his therapist uses hypnosis(extremely focused concentration) that would help him to remain relaxed during the time of dental surgery as his entire concentration or focus would be devoted to a specific thing. Thus, he would not be able to experience pain while undergoing surgery and feel relaxed. Therefore, Danny has the most probable chances of being successful as the others are either using the method inappropriately or for an inappropriate cause('recall the night he was supposedly abducted by aliens'). Hence, <u>option B</u> is the correct answer.
