Which statement best describes how scientists and engineers work together in the research and development cycle?
A. Engineers develop a new technology, and then scientists use it to
make a new discovery.
B. Engineers do experiments to answer questions about nature, and
then scientists use the results to create a new technology.
C. Scientists develop a theory, and then engineers perform
experiments to verify its accuracy.
D. Scientists make designs based on engineering knowledge and
then make it available for public use.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

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.
