An automobile company displays a die-cast model of its first car, made from 8.70 kg of iron. To celebrate its hundredth year in

lakkis [162]

Answer:

21.28 kg

Explanation:

Density of iron = 7890 kg/m³ = $\rho_i$

Mass of iron = 8.7 kg= $m_i$

Volume of gold = Volume of iron = v

Density = Mass / Volume

$\rho_i=\frac{m_i}{v}\\\Rightarrow v=\frac{m}{\rho}\\\Rightarrow v=\frac{8.7}{7890}$

Density of gold = 19300 kg/m³= $\rho_g$

Mass of iron = $m_i$

$\rho_g=\frac{m_g}{v}\\\Rightarrow m=\rho_g v\\\Rightarrow m_g=19300\times \frac{8.7}{7890}\\\Rightarrow m_g=21.28\ kg$

Mass of gold needed to make the new model is 21.28 kg

If an R = 1-kΩ resistor, a C = 1-μF capacitor, and an L = 0.2-H inductor are connected in series with a V = 150 sin (377t) volts

fgiga [73]

Answer

given,

R = 1-kΩ = 1000 Ω

C = 1-μF

L = 0.2-H

V = V_max sin( ω t)

comparing

V = 150 sin ( 377 t)

ω = 377

$\chi_c = \dfrac{1}{\omega C}$

$\chi_c = \dfrac{1}{377 \times 1 \times 10^{-6}}$

$\chi_c = 2652.5\Omega$

$\chi_L =377 \times 0.2$

$\chi_L =75.4\ \Omega$

Impedance,

$Z = \sqrt{R^2+(\chi_L-\chi_c)^2}$

$Z = \sqrt{1000^2+(75.4 -2652.5)^2}$

Z = 2764.3 Ω

now,

V_{max} = 150 V

$I_{max} = \dfrac{V}{Z}$

$I_{max} = \dfrac{150}{2764.3}$

$I_{max} = 0.0543$

$I_{max} = 54.3\ mA$
