Option C is the untrue statement.
 
        
                    
             
        
        
        
We can use the kinematic equation

where Vf is what we are looking for
Vi is 0 since we start from rest
a is acceleration
and d is the distance
we get
(Vf)^2 = (0)^2 + 2*(2)*(500)
(Vf)^2 = 2000
Vf = about 44.721
or 44.7 m/s   [if you are rounding this by significant figures]
 
        
        
        
C. Amount of oxygen
The others either change but don’t decrease or they increase.

Answer:
M = 222 fringes
Explanation:
given
λ = 559 n m = 559 × 10⁻⁹ m
radius = 0.026 mm = 0.026 ×10⁻³ m
length of the glass plate = 22.1 ×10⁻² m
using relation


  = 221.79  
  = 221 (approx.)
hence no of bright fringe
M = m + 1
    = 221 +1 
M = 222 fringes
