As charges move in a closed loop, they
mamaluj [8]

As charges move in a closed loop, they gain as much energy as they lose.

<h3>What is principle of conservation of energy?</h3>
  • According to the principle of conservation of energy, in a closed or isolated system, the total energy of the system is always conserved.
  • The energy gained by the particles or charges in a closed system is equal to the energy lost  by the charges.

Thus, we can conclude the following based on principles of conservation of energy;

  • As charges move in a closed loop, they gain as much energy as they lose.

Estimate the distance (in cm) between the central bright region and the third dark fringe on a screen 5.00 m from two double sli
Artist 52 [7]

Answer:

y = 1.75 cm

Explanation:

In the double-slit experiment the equation for destructive interference is

           d sin tea = (m + ½)

λ

let's use trigonometry to find the angle

         tan θ = y / L

as all the experiment does not occur at small angles

          tan θ = sin θ / cos θ = sin θ = y / L

we substitute

        y = (m + 1/2 ) λ  L / d

we calculate

         y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³

         y = 1.75 10⁻² m

         y = 1.75 cm
