Sven has recently developed a new type of solar cell. When he tests how efficient it is at converting light energy into electrical energy, he finds that it is 54% efficient. Sven publishes these findings in a scientific journal. Martha decides to repeat Sven's experiment, but she finds that the new solar cell is only 38% efficient at converting light energy into electrical energy. What should Martha do with her new findings?

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.
