Answer:

Explanation:
Mass of Earth, 
Mass of Moon, 
The distance between Earth and the Moon is, 
We need to find the force of gravitational attraction between the Earth and the moon. The force of gravity is given by :

So, the required force is  .

Answer:
Number of turns on the secondary coil of the adapter transformer is 10.
Explanation:
For a transformer,
     
where  is the voltage induced in the secondary coil
 is the voltage induced in the secondary coil
             is the voltage in the primary coil
 is the voltage in the primary coil
            is the number of turns of secondary coil
 is the number of turns of secondary coil
           is the number of turns of primary coil
 is the number of turns of primary coil
From the given question,
      =
 = 
⇒     =
 = 
             = 9.999733
   ∴    = 10 turns
 = 10 turns
 
        
                    
             
        
        
        
Answer: Sara tries turning a test tube upside down to collect a gas. 
A scientist is considered to be creative when he approaches a problem with new different ways. The conventional way is to design an experiment and take detailed notes, reading referenced studies previously done. Sara tries turning a test tube upside down to collect a gas is a creative way as Sara tries something different. 
 
        
                    
             
        
        
        
Answer:
D
Explanation:
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
