Answer:
377 m 
Explanation:
number of turns, N = 65 
θ = 36°
B1 = 200 micro Tesla 
B2 = 600 micro tesla 
t = 0.4 s 
induced emf, e = 80 mV 
Let a be the side of the square coil. 



a = 1.45 m 
Total length of the wire, L = N x 4a = 65 x 4 x 1.45 = 377 m 
Thus, the length of the wire is 377 m. 
 
        
             
        
        
        
False, it does create pollution form the smoke stacks and after the process is done they have barrels of toxic waste 
        
             
        
        
        
Answer:
The true weight of the aluminium is  4.5021 kg
 4.5021 kg
Explanation:
Given data
 = 4.5 kg
 = 4.5 kg
 = 1.29
 = 1.29 
 = 2.7×
 = 2.7× 
The true mass of the aluminium is given by 

Put all the values in above equation we get

 4.5021 kg
 4.5021 kg
Therefore the true weight of the aluminium is  4.5021 kg
 4.5021 kg
 
        
             
        
        
        
From the equations of linear motion,
v² = u² + 2as where v is the final velocity, u is the initial velocity and a is the gravitational acceleration, and s is the displacement,
Thus, v² = u² -2gs, but v=0
hence, u² = 2gs
                = 2×9.81×0.43
                = 8.4366
            u = √8.4366
               =2.905 m/s
Hence the initial velocity is 2.905 m/s
 Then using the equation v= u +gt .
Therefore, v = u -gt. (-g because the player is jumping against the gravity)
but, v = 0
Thus, u= gt
Hence, t = u/g
              = 2.905/9.81
              = 0.296 seconds
        
             
        
        
        
Off the top of my head, I only know 9 and 11, so I'll answer those two.
9) A heterotroph is an organism that relies on other organisms for food/energy
    An autotroph can produce its own food from inorganic compounds (light)
11) Vascular plants have specialized tubes for transporting nutrients
      Nonvascular plants do not have such tubes and are simpler
