Four copper wires of equal length are connected in series. Their cross-sectional areas are 1.6 cm2 , 1.2 cm2 , 4.4 cm2 , and 7 c

EleoNora [17]

Answer:

63.8 V

Explanation:

We are given that

$A_1=1.6 cm^2=1.6\times 10^{-4} m^2$

$1 cm^2=10^{-4} m^2$

$A_2=1.2 cm^2=1.2\times 10^{-4} m^2$

$A_3=4.4 cm^2=4.4\times 10^{-4} m^2$

$A_4=7 cm^2=7\times 10^{-4} m^2$

Potential difference,V=140 V

We know that

$R=\frac{\rho l}{A}$

According to question

$l_1=l_2=l_3=l_4=l$

In series

$R=R_1+R_2+R_3+R_4$

$R=\rho l(\frac{1}{A_1}+\frac{1}{A_2}+\frac{1}{A_3}+\frac{1}{A_4})$

$R=\rho l(\frac{1}{1.6\times 10^{-4}}+\frac{1}{1.2\times 10^{-4}}+\frac{1}{4.4\times 10^{-4}}+\frac{1}{7\times 10^{-4}})$

$R=\rho l(18284.6)$

$I=\frac{V}{R}=\frac{140}{\rho l\times 18284.6}$

Potential across 1.2 square cm= $V_1=IR_1=\frac{140}{\rho l\times 18284.6}\times \rho l(\frac{1}{1.2\times 10^{-4}}=63.8 V$

Hence, the voltage across the 1.2 square cm wire=63.8 V

The wavelength of light visible to the human

lapo4ka [179]

Answer: 4.2817 × 10^14 s^-1

Explanation:

The term "wave speed" is described as the distance covered by a wave in specific time duration. The wave speed (v) can be mathematically expressed as:

v=fλ

Where;

F= frequency which is the number of waves that pass a fixed point per unit time and it is also the number of cycles or vibrations undergone during pet unit of time by a body in periodic motion

λ= wavelength which is the distance between successive crests of a wave.

Given the data,

Wavelength λ= 7×10^-7m

Speed of light c= 2.99792 × 10^8 m/s

Frequency of visible light can be given as:

Frequency= speed of light/wavelength

Frequency = (2.99792 × 10^8 m/s) / (7×10^-7m)

Frequency= 4.2817 × 10^14 s^-1

Therefore, the frequency of the light wave is 4.2817 × 10^14 s^-1
