Since any first distanced1=λ(2N1−1)/4, whereN1= 1,2,3,· · ·will do, the first distance only cannot be used to know the wavelength.The space between the resonances is ½ a wavelength, soλ= 2 [d2−d1]= 2 [(35 cm)−(25 cm)]= 20 cm.
The frequency isF = vλ=343 m/s2 [(35 cm)−(25 cm)]= 1715 Hz.
The energy is 3.06 electronvolts, E = 3.06eV
1eV = 1.6 * 10^-19 J
3.06 eV = 3.06* 1.6 * 10^-19 J = 4.896 * 10^-19 J
Answer:
B splits and goes through two components
Explanation:
- A series circuit is a circuit in which the components are all connected along the same branch: as a result, the current flowing through the components is the same, while the sum of the potential differences across each component is equal to the emf of the battery
- A parallel circuit is a circuit consisting of separate branches, so that each branch has a potential difference equal to the emf of the battery. As a result, in such a circuit the current in the circuit splits and goes through the different branches/components.
So, the correct answer is
B splits and goes through two components
