Explanation:
Distance covered by the satellite in 24 hours
s=2πr
=2×3.14×42250=265464.58 km
Therefore speed of satellite,
v=
time taken
distance travelled
=
24×60×60
265464.58
=3.07 km s
−1
Answer:
i think the answer is 12 ohms
plz mark me as brainliest :)
Metals are not brittle so it can’t be the first one or the third one, both metalloids and metals are shiny so it can’t be the second one.
