Answer:
1.07 nT
Explanation:
We know that E/B = c where E = electric field amplitude = 320 mV/m = 0.32 V/m, B = magnetic field amplitude and c = speed of light = 3 × 10⁸ m/s.
So, B = E/c 
Substituting E and c into B, we have
B = E/c 
= 0.32 V/m ÷ 3 × 10⁸ m/s 
= 0.1067 × 10⁻⁸ T 
= 1.067 × 10⁻⁹ T 
= 1.067 nT 
≅ 1.07 nT
 
        
             
        
        
        
Answer:
C. Energy is used for life processes (e.g. Movement, breathing, etc.)
Explanation:
As we pass from one trophic level to the next, only 10% of energy is transferred from the first trophic level to the next. This is because a lot of energy is lost to the surroundings and rest is utilised by the organism.
 
        
                    
             
        
        
        
If your machine has a mechanical advantage of 2.5, then WHATEVER force you apply to the input, the force at the output will be 2.5 times as great.
If you apply 1 newton to the machine's input, the output force is 
                 (2.5 x 1 newton)  =  2.5 newtons.
If you apply 120 newtons to the machine's input, the output force is 
                 (2.5 x 120 newtons)  =  300 newtons.

Answer:
B ) Ascend using my buddy alternative air source / make an emergency Ascent
Explanation:
From the description it can be seen his buddy is close by of which he can easily use the alternative air source. Also we can see that he is closer to the water surface than his buddy, of which controlled emergency swimming ascent is highly favourable in this condition.
