The efficiency of any machine is given by:

efficiency = output obtained / input given

Substituting the values,

Efficiency = 105 / 150

Efficiency = 0.7

Converting this to a percentage, the efficiency of the hammer is 70%.

This is a fairly high efficiency, and this is due to the fact that the hammer is a simpler machine. The more complex a machine is, the greater are the losses in it due to friction, meaning there is a lower efficiency.

Explanation:

im not entirely sure what you're asking.

first of all the mood needs to be defined: it is obviously a mood of deceitful relief and serenity. why? because the cape horn is one of the most violent maritime regions of earth and although it has been left behind, it is a personification of ahab’s delirium and the fact that the end of the passage speaks about it about being “hidden” but “raving” immediately conveys the feeling the calm is not permanent but fleeting.

furthermore, the oxymoron “mild stun'sails” is the first instance of such feeling as the adjective “mild” is associated with “stunned” underscoring the fleeting nature of this “tranquil” moment. and the contrasts keep piling up, with the opposition between “dark den” and “blessed light and air” to end with the final conclusion that leaves the reader with the uneasy knowledge that this is just a reprieve.
