The weight of a space shuttle is about 20.0 million newtons. what is the space shuttle's weight when it is traveling through outer space?

the answer is 0.0 newtons

Answer

when a space shuttle traveled through outer space that time it is far away from the gravity of any planet, star or moon. It means gravitational force acting on the space shuttle is zero(g=0)

We know that weight of space shuttle=

here m- mass of space shuttle

and g=gravity

but gravity in outer space= 0

therefore,

weight of space shuttle in outer space=0

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
