In an electrical circuit 200mC of charge flows through a 50kohm resistor in 90 seconds. What is the power

ss7ja [257]

Answer: $0.2464\ W$

Explanation:

Given

Charge $Q=200\ mC$

Resistance $R=50\ k\Omega$

Time $t=90\ s$

Charge is the amount of current flown in a particular time

$Q=It\\\Rightarrow 200\times 10^{-3}=I\times 90\\\\\Rightarrow I=\dfrac{200\times 10^{-3}}{90}\\\\\Rightarrow I=2.22\times 10^{-3}\ A$

Power is the given by $P=I^2R$

Insert values

$\Rightarrow P=\left(2.22\times 10^{-3}\right)^2\times 50\times 10^3\\\\\Rightarrow P=246.42\times 10^{-3}\ W\\\\\Rightarrow P=0.2464\ W$

The power is in the circuit is $0.2464\ W$ .

Two clear but non-mixing liquids each of depth 15 cm are placed together in a glass container. The liquids have refractive indic

vladimir1956 [14]

Answer:

The apparent depth d = 19.8495 cm

Explanation:

The equation for apparent depth can be expressed as:

$d = \dfrac{d_1} {\mu_1}+\dfrac {d_2}{\mu_2}$

here;

$d_1 = d_2 = 15 \ cm$

$\mu_1$ = refractive index in the first liquid = 1.75

$\mu_2$ = refractive index in the second liqquid= 1.33

∴

$d = \dfrac{15}{1.75}+\dfrac{15}{1.33}$

$d = 15( \dfrac{1}{1.75}+\dfrac{1}{1.33})$

$d = 15( 0.5714 +0.7519)$

d = 15(1.3233 ) cm

d = 19.8495 cm

choli [55]

Answer:

$\frac{dB}{dt} = 11.55 T/s$

Explanation:

As we know that flux of magnetic field from the closed loop is given by

$\phi = BAcos30[tex]now by Faraday's law we know[tex]EMF = \frac{d\phi}{dt}$

now we will have

$EMF = Acos30\frac{dB}{dt}$

now we have

$A = 1 m^2$

EMF = 10 Volts

$10 = 1 (cos30)\frac{dB}{dt}$

$\frac{dB}{dt} = \frac{20}{\sqrt3}$

$\frac{dB}{dt} = 11.55 T/s$
