Answer:
The values is  
The  direction is out of the plane 
Explanation:
From the question we are told that 
   The  magnitude of the electric field is  
   
The  magnitude of the magnetic field is mathematically represented as 
        
 where c is the speed of light with value 
       
      
Given that the direction off the electromagnetic wave( c ) is  northward(y-plane ) and  the electric field(E) is eastward(x-plane ) then the magnetic field will be acting in the out of the page  (z-plane  )
      
 
        
             
        
        
        
Answer:
The new period will be √6 *T
Explanation:
period ,T=2π√(L/g)       ................equation 1
where T is the period on earth
gravitational acceleration on the moon is g/6
T1 = 2π√[L/(g/6)]
T1=2π√(6L/g)               ...............equation 2
divide equation 2 by 1
T1/T =2π√(6L/g)÷2π√(L/g)
T1/T =√(6L/L)
T1/T =√6
T1 = √6 *T
 
        
             
        
        
        
 W work
F force 
s distance
If F = constant:
W₁ = F·s
If you triple the force and the distance:
W₂ = 3F · 3s = 9 F·s = 9 W₁
        
                    
             
        
        
        
Answer:
Hyperopia
Explanation:
      In hyperopia ,people face difficulties  to see close up object , but can see object easily which are at a distance.
The main reason of hyperopia is our eyeball.When our eyeball become too  short , then light focus behind the retina. Sowe will face problem to see near object but we can see distance object easily. Hyperopia is the opposite of nearsightedness. Hyperopia can be corrected by using contact lenses.
 
        
             
        
        
        
Answer:
 14 N 
Explanation:
The tension in the second string is puling both the masses of 20 kg and 8 kg with acceleration of 0.5 m s⁻²
So tension in the second string = total mass x acceleration 
= 28 x .5 = 14 N . Ans..
