An astronaut is taking a space walk near the shuttle when her safety tether breaks. what should the astronaut do to get back to
sergeinik [125]
The best way in handling in this situation is that in order for the astronaut to be able to get back to the shuttle is that he or she should take an object from his or her tool belt and to be thrown out away from the shuttle. This will allow her to weight lightly and safely return to the shuttle and would be easier for his or her to do so.

Study the interaction of the light rays with the mediums. Classify the medium in each image as being transparent or opaque.
Tresset [83]

Answer:

a) transparent

b) transparent

c) opaque

Explanation:

In the first one, the light rays go completely through, so it is transparent.

The second one I'm not too sure about. It is refraction so it's going through a different material, but the fact that it went through makes me say transparent.

Last one, the light rays are reflecting off the surface so it's opaque.

Please feel free to correct me if I'm wrong. This is just my understanding

How long does it take a message to travel from earth to a spacecraft at mars at its farthest from earth (about 400 million km)?
seraphim [82]
<span>A message needs to be traveled to mars from earth. Distance between Earth and Mars (given) s = 400 million km
 Speed of light = 3.00—10^5 km/ sec
 We know Velocity = distance / time => time = distance / velocity
 Time taken t = 400 million km / 3.00—10^5 = 400 x 10^6 / 3 x 10^5 = 1333.3 sec Time taken t = 22 min</span>
