Answer:
0.82 mm
Explanation:
The formula for calculation an  bright fringe from the central maxima is given as:
 bright fringe from the central maxima is given as:

so for the distance of the second-order fringe when wavelength  = 745-nm can be calculated as:
 = 745-nm can be calculated as:

where;
n = 2
  = 745-nm
 = 745-nm 
D = 1.0 m
d = 0.54 mm
 substituting the parameters in the above equation; we have:

 = 0.00276 m
 = 0.00276 m
 = 2.76 × 10 ⁻³ m
 = 2.76 × 10 ⁻³ m
The distance of the second order fringe when the wavelength  = 660-nm is as follows:
 = 660-nm is as follows:

 = 1.94 × 10 ⁻³ m
 = 1.94 × 10 ⁻³ m
So, the distance apart the two fringe can now be calculated as:

 = 2.76 × 10 ⁻³ m - 1.94 × 10 ⁻³ m
 = 2.76 × 10 ⁻³ m - 1.94 × 10 ⁻³ m
 = 10 ⁻³ (2.76 - 1.94)
 = 10 ⁻³ (2.76 - 1.94)
 = 10 ⁻³ (0.82)
 = 10 ⁻³ (0.82)
 = 0.82 × 10 ⁻³ m
 = 0.82 × 10 ⁻³ m
 =  0.82 × 10 ⁻³ m
 =  0.82 × 10 ⁻³ m 
 = 0.82 mm
 = 0.82 mm
Thus, the distance apart the second-order fringes for these two wavelengths  = 0.82 mm

Explanation:
The area of the circular loop is given by:

The magnetic flux is given by:

 is parallel to
 is parallel to  and
 and  is constant in magnitude and direction therefore:
 is constant in magnitude and direction therefore:

Part A)
initially the flux is 
after the interval ![\Delta t= 2.4 [m/s]](https://tex.z-dn.net/?f=%5CDelta%20t%3D%202.4%20%5Bm%2Fs%5D) 
 
the flux is

now, the EMF is defined as:
 ,
,
if we consider ![\Delta t= 2.4 [m/s]](https://tex.z-dn.net/?f=%5CDelta%20t%3D%202.4%20%5Bm%2Fs%5D) very small then we can re-write it as:
 very small then we can re-write it as:

 
 
then:
![\epsilon =- \frac{-0.12}{0.0024} = 50 [V]](https://tex.z-dn.net/?f=%5Cepsilon%20%3D-%20%5Cfrac%7B-0.12%7D%7B0.0024%7D%20%3D%2050%20%5BV%5D)
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
 
        
             
        
        
        
Answer:the pressure depends on gas and it will be half as much underwater 
Explanation:
Water pressure increases with the depth of the water. This is because the weight of the column of water above the object increases. But a large, shallow pond may have more water in it than a small, deep pond. 
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .
