Bruce Lee's famous one-inch punch is a technique he taught many of his students. This punch is able to produce 681 N of force in a very short amount of time. Assuming Bruce Lee had rectangular fists measuring 0.0889m in length and 0.0508m in width, F how much pressure was produced by this punch?

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

the answer is 0.42 is that is an option. this question provides no info
