Magnetic Battery

This is a device which converts magnetic field energy into electrical energy so in this part we got the electric energy out of it

Coil Magnet

This type of magnet is always in shape of coil which will produce the magnetic field along the axis.

Coil circuit

This is just type of the circuit which will produce the current in closed loop.

Electromagnet

In electromagnets we got the magnetic field energy which is converted by electric energy i.e. in this form we have to supply the current in the circuit and then it will produce the magnetic field of that current

So correct answer is electromagnet

A circular parallel plate capacitor is constructed with a radius of 0.52 mm, a plate separation of 0.013 mm, and filled with an

olya-2409 [2.1K]

Answer:

289282

Explanation:

r = Radius of plate = 0.52 mm

d = Plate separation = 0.013 mm

A = Area = $\pi r^2$

V = Potential applied = 2 mV

k = Dielectric constant = 40

$\epsilon_0$ = Electric constant = $8.854\times 10^{-12}\ \text{F/m}$

Capacitance is given by

$C=\dfrac{k\epsilon_0A}{d}$

Charge is given by

$Q=CV\\\Rightarrow Q=\dfrac{k\epsilon_0AV}{d}\\\Rightarrow Q=\dfrac{40\times 8.854\times 10^{-12}\times\pi \times (0.52\times 10^{-3})^2\times 2\times 10^{-3}}{0.013\times 10^{-3}}\\\Rightarrow Q=4.6285\times 10^{-14}\ \text{C}$

Number of electron is given by

$n=\dfrac{Q}{e}\\\Rightarrow n=\dfrac{4.6285\times 10^{-14}}{1.6\times10^{-19}}\\\Rightarrow n=289281.25\ \text{electrons}$

The number of charge carriers that will accumulate on this capacitor is approximately 289282.

zavuch27 [327]

Answer:

water is in the vapor state,

Explanation:

We must use calorimetry equations to find the final water temperatures. We assume that all energy is transformed into heat

E = Q₁ + $Q_{L}$

Where Q1 is the heat required to bring water from the current temperature to the boiling point

Q₁ = m $c_{e}$ ( $T_{f}$ -T₀)

Q₁ = 50 4180 (100 - 37)

Q₁ = 1.317 10⁷ J

Let's calculate the energy so that all the water changes state

$Q_{L}$ = m L

$Q_{L}$ = 50 2,256 106

$Q_{L}$ = 1,128 10⁸ J

Let's look for the energy needed to convert all the water into steam is

Qt = Q₁ + $Q_{L}$

Qt = 1.317 107 + 11.28 107

Qt = 12,597 10⁷ J

Let's calculate how much energy is left to heat the water vapor

ΔE = E - Qt

ΔE = 10¹⁰ - 12,597 10⁷

ΔE = 1000 107 - 12,597 107

ΔE = 987.4 10⁷ J

With this energy we heat the steam, clear the final temperature

Q = ΔE = m $c_{e}$ ( $T_{f}$ -To)

( $T_{f}$ -T₀) = ΔE / m $c_{e}$

$T_{f}$ = T₀ + ΔE / m $c_{e}$

$T_{f}$ = 100 + 987.4 10⁷ / (50 1970)

$T_{f}$ = 100 + 1,002 10⁵

$T_{f}$ = 1,003 10⁵ ° C

This result indicates that the water is in the vapor state, in realizing at this temperature the water will be dissociated into its hydrogen and oxygen components
