5.0j as we know that work is derived as force into displacement so 5*1=5si force will be 5.0j

Answer:
Explanation:
The man is moving on a circular path . The reaction of wall is providing centripetal force .so 
R = mv² / r 
Frictional force = μR where  μ is coefficient of friction 
= μ x mv² / r 
Frictional force = μ x mv² / r 
 
        
             
        
        
        
Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
 
        
             
        
        
        
Answer:
doubled
Explanation:
F=ma1----------(1)
2F = ma2-------(2)
Divide 2nd equation by 1st one
we get a1×2=a2
