Meteorologists look at data help from the computer about temperature, pressure, humidity, and wind speed, among many other data points to try and accurately predict the weather.
 
        
             
        
        
        
Answer : The correct option is, Malleable, shiny, and able to conduct heat or electricity.
Explanation:
Metals : Metals are the elements which can easily loose electrons and forms cations.
Properties of metals :
- They are lustrous (shine).
- They are malleable and ductile (flexible).
- They conduct heat and electricity.
- The metallic oxides are basic in nature.	
- They form cations in an aqueous solution.	
Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.
Properties of non-metals :
- They are non-lustrous.
- They are brittle and hard in nature.
- They do not conduct heat and electricity.
- The non-metallic oxides are acidic in nature.	
- They form anions in an aqueous solution.
Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.
 
        
                    
             
        
        
        
Answer: B. Was twice as tall
Explanation: The strength of the gravitational force between two objects depends on two factors, mass and distance. If the distance is doubled, the force of gravity is one-fourth as strong as before.

Answer:
C3H8 + 5O2 => 3CO2 + 4H2O 
Explanation: 
Hydrocarbon combustion is the reaction between a hydrocarbon and O2 producing CO2 and water. 
C3H8 + O2 => CO2 + H2O 
First we balance the C and H.
C3H8 + O2 => 3CO2 + 4H2O 
Now we balance O for the answer!
C3H8 + 5O2 => 3CO2 + 4H2O
