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

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. Therefore, it would be the last one because both metalloids and metals are shiny and both are solids at room temperature because it is not a high enough melting point. 
ANSWER: Both are shiny and are solid at room temperature.
        
                    
             
        
        
        
Pretty sure physical, a chemical change would be something of the time of acid rain, meanwhile physical changes are the ones that affect the form not the actual chemical composition
