Aspace shuttle travels at the rate of 3,094 miles per hour to reach its orbit at a height of 300 km from earth. if 1 kilometer equals 0.62 miles, which of these conclusions is correct about the space shuttle?
it reaches its orbit in about 4 minutes.
it reaches its orbit in about 30 minutes.
after 5 minutes, it is 60 kilometers away from its orbit.
after 10 minutes, it is 60 kilometers away from its orb

Option A, It reaches its orbit in about 4 minutes.

Explanation:

The speed with which the space shuttle moves miles per hour.

The distance to which this space shuttle has to move is kilometers

Given

KM miles

So KM miles

Lets explore each option one by one

Option D-

So, the distance covered by space shuttle in 10 minutes is equal to

hence , option D is incorrect

Option C -

the distance covered by space shuttle in 5 minutes is equal to

miles

hence , option C is incorrect

Option B-

Time taken by space shuttle to reach orbit at 186 miles distance

hence , option B is incorrect

Therefore option A is correct

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
