Answer:
an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
 
        
             
        
        
        
Average acceleration  =  (change in speed) / (time for the change) .
  
Change in speed = (ending speed) - (beginning speed)
                       =  (9.89 miles/hour) - (2.35 yards/second)  = 26,839.2 ft/hr
Acceleration  =  (26,839.2 ft/hr) / (4.67 days)  =  2,873.58 inch/hour²

Answer:
 5.71×10¹⁴ Hz
Explanation:
Applying,
v = λf................. Equation 1
Where v = speed of the electromagnetic radiation, λ = wavelength of the electromagnetic radiation, f = frequency
make f the subject of the equation
f = v/λ............. Equation 2
From the question,
Given: λ = 525 nm = 5.25×10⁻⁷ m,
Constant: Speed of electromagnetic wave (v) = 3.0×10⁸ m/s
Substitute these values into equation 2
f = (3.0×10⁸)/(5.25×10⁻⁷)
f = 5.71×10¹⁴ Hz
Hence the frequency of light is 5.71×10¹⁴ Hz
 
        
             
        
        
        
The answer is destructive interference.  You have this for both C and D.  I suspect one of C or D is supposed to be constructive interference...  But destructive interference is the answer
