In an RL series circuit, an inductor of 4.74 H and a resistor of 9.33 Ω are connected to a 26.4 V battery. The switch of the cir

cuit is initially open. Next close the switch and wait for a long time. Eventually the current reaches its equilibrium value. At this time, what is the corresponding energy stored in the inductor? Answer in units of J.

Answer:

The energy is   U =  18.98 \  J

Explanation:

From the question we are told that

   The inductor is  L  =  4.74 \ H

    The resistance of the resistor is R =  9.33 \  \Omega

    The voltage of the battery is V =  26.4 \  V

Generally the current flowing in the circuit is mathematically represented as

      I =  \frac{V}{R}

=>   I =  \frac{26.4}{9.33 }

=>   I =  2.83 \ A

Generally the corresponding energy stored in the circuit is  

       U =  \frac{1}{2} * L  *  I^2

        U =  \frac{1}{2} *  4.74  *  2.83 ^2

       U =  18.98 \  J

distant galaxy emits light that has a wavelength of 434.1 nm. On earth, the wavelength of this light is measured to be 438.6 nm.
a_sh-v [17]

Answer:

The speed of the galaxy relative to the Earth is 3.09\times 10^6\ m/s.

Explanation:

We have,

(a) Wavelength emitted by light at distant galaxy is 434.1 nm. On earth, the wavelength of this light is measured to be 438.6 nm. It can be seen that the wavelength of light reduces as it reaches Earth. It is called Red shift. As per Doppler's effect, we can say that the galaxy is receding from the Earth.

(b) Let v is the speed of the galaxy relative to the Earth. It can be given by :

v=c(\dfrac{\lambda'}{\lambda}-1)\\\\v=3\times 10^8\times (\dfrac{438.6 }{434.1 }-1)\\\\v=3\times 10^8\times (\dfrac{438.6}{434.1}-1)\\\\v=0.0103\cdot3\cdot10^{8}\\\\v=3.09\times 10^6\ m/s

So, the speed of the galaxy relative to the Earth is 3.09\times 10^6\ m/s.

What is the mathematical relationship between wavelength and velocity?
gavmur [86]

Answer:A wave has a wavelength λ, which is the distance between adjacent identical parts of the wave. The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ.
