Explanation:

first find the volume of room --->

$v \: = 10 \times 12 \times (400 \times {10}^{ - 2} ) \times = 480 \: {m}^{3}$

then find the mass

$mass \: = \: density \: \times \: volume \: = 480 \times 1.26 = 604.8 \: kg$

You are given a parallel plate capacitor that has plates of area 29 cm2 which are separated by 0.0100 mm of nylon (dielectric co

GalinKa [24]

Answer:

20.60 kV

Explanation:

Capacitance of parallel plates without dielectric between them is:

$C=\frac{\varepsilon_{0}A}{d}$

with d the distance between the plates, A the area of the plates and ε₀ the constant $8.85419\times10^{-12}\frac{C^{2}}{Nm^{2}}$ , so :

$C_0=\frac{(8.85419\times10^{-12})(0.0029)}{0.0100\times10^{-3}}=2.57\times10^{-9} F$

But the dielectric constant is defined as:

$k=\frac{C}{C_{0}}$

With C the effective capacitance (with the dielectric) and Co the original capacitance (without the dielectric). So, the new capacitance is:

$C=kC_0$

But capacitance is related with voltage by:

$C=\frac{Q}{V}$

with Q the charge and V the voltage, using the new capacitance and solving for V:

$kC_0=\frac{Q}{V}$

$V=\frac{Q}{kC_0}=\frac{0.18\times10{-3}}{(3.4)(2.57\times10^{-9})}=20599.68V=20.60 kV$

Why is a spectrum of colors produced when white light passes through a prism?

shutvik [7]

Answer:

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
