Physics

LekaFEV [45]3 years ago
6 0

Answer:

Group 18 elements are noble gasses which are stable. They have a full valence shell so they are don't typically react too much. Group 17 only needs one more valence electron so these are most often paired with group 1 elements. Group 17 are Halogens and most often react with Alkali metals. Example: NaCl (Na group 1 | Cl group 17)

How many seconds will it take for a the International Space Station to travel 450 km at a rate of 100 m/s?
SVEN [57.7K]

Time = (distance) / (speed)

<em></em>

Time = (450 km) / (100 m/s)

Time = (450,000 m) / (100 m/s)

Time = <em>4500 seconds </em>(that's 75 minutes)

Note:

This is about HALF the speed of the passenger jet you fly in when you go to visit Grandma for Christmas.

If the International Space Station flew at this speed, it would immediately go ker-PLUNK into the ocean.

The speed of the International Space Station in its orbit is more like 3,100 m/s, not 100 m/s.
