Answer:
Metal vase
Explanation:
Pure water is not a good conductor, and neither is plastic or cotton. Metal is the only one of the four that actually is a good conductor. For example, lighting hitting metal, this happens because the lightning connects to anything that has some kind of conductant.
 
        
             
        
        
        
Well, I'll try to write the formula in a way that's not confusing, 
but I'm afraid it might be slightly confusing anyway.
When you're working with dB, the basic rule is
       A change of 10 dB means either multiplying or dividing by 10 .
     Multiply something by 10  ==>  it increases by 10 dB.
     Divide something by 10   ==>  it decreases by 10 dB.
It turns out that another way to write all of this is . . .
     An increase of 10 dB ===> multiply the original amount by 10¹  
     An increase of 20 dB ===> multiply the original amount by 10² 
     An increase of, say, 7 dB ===> multiply the original amount by 10⁰·⁷ 
     A decrease of 10 dB ===> multiply the original amount by 10⁻¹ 
     A decrease of 30 dB ===> multiply the original amount by 10⁻³ 
     A decrease of, say, 13 dB ===> multiply the original amount by 10⁻¹·³
This question says:  The sound increases by  5 dB .
That means the original 'intensity' or 'power' of the sound
is multiplied by
                           10⁰·⁵  =  √10  =  about 3.162 (rounded) .  
From the choices listed, the closest one is  (c).
        
                    
             
        
        
        
Answer:
Because the force one needs to apply is reduced.
Explanation:
- Work can be expressed in terms of force and distance as follows,
                         Work = Force × distance
- To be more precise, the selection of these two parameters should be in a manner that the distance is what the line of action of the force traces.
- It is obvious that for a given amount of work when one parameter is changed the other changes to counteract the change of the first one.
- Imagine the situation shown in the attached figure. The amount of work that needs to be done during the lifting of the mass to a height of  vertically is vertically is . .
- On the slope, however, one needs to push the object an  distance up to get the object to that distance up to get the object to that height ultimately. height ultimately.
- The work he does on the slope is  and since and since , , . .
- The force that needs to be applied is less than that applied in the vertical lift. Hence it feels easier.             #SPJ4
