Mercury is very different than Earth. I think Mercury is a very hot planet, and because of the gravity and other conditions - look these up online - Humans and other life on Earth cannot live on Mercury, much less visit without being fully protected. Temperature on Mercury 426 degrees Celsius, about 800 degrees fahrenheit - very hot. You would want your space craft to completely protected from these temperatures, think of some materials you could use, and how thick you would need them? What material protects from heat? As far as vacuum conditions, and gravity, you will need to have that included as well.Maybe you would just wear a type of clothing to protect against bumping around in your space craft since you will not have gravity, you will also want to think about food!
A survey of the entire population of students on the cross country team. That way, all the info you get back is 100% accurate as everyone participated and gave you an exact number of hours. With this info, you can find the average
the greatest possible error for meters is 1/2 the increments
since 18.9 is to the tenths place
1/2 x 1/10 = 0.05
so greatest possible error for 18.9 is 0.05m
