A source charge generates an electric field of 1236 N/C at a distance of 4 m. What is the magnitude of the source charge?
guajiro [1.7K]

The correct answer to the question is-  2.2\ \mu C

CALCULATION:

As per the question, the electric field generated by the source charge is 1236  N/C at a distance of 4 m.

Hence , electric field  E =  1236 N/C.

The distance of the point R = 4m

We are asked to calculate the charge possessed by the source.

The electric field produced by a source charge of Q at a distance R is calculated as -

                    Electric field E = \frac{1}{4\pi \epsilon_{0}}\frac{Q}{R^2}

Here, \epsilon_{0} is called the absolute permittivity of the free space.

Hence, the charge of source is calculated as -

                                         Q = E\times 4\pi \epsilon_{0}\times R^2

                                            = 1236\times \frac{1}{9\times 10^9}\times (4)^2\ Coulomb

                                            = 2197.33\times 10^{-9}\ C

                                             = 2.19733\times 10^{-6}\ C

                                             = 2.2\ \mu C

Hence, the charge of source is 2.2\ \mu C

Which statement correctly describes magnetism? (2 points) Metals can become magnetic if they have many spinning electrons that c
m_a_m_a [10]
I can interpret this as it's somewhat of all of those, due to the fact that for one thing think of the earth it's a spinning ball of liquid iron, nickel due to one law stating hot liquid metal spinning around creates magnetic fields, ferro magnetic metals are ones such as magnetite which is a natural magnet, it can be found in nature theres a region in the gobi desert that will make a compass needle dance since its surrounded by magnetic rock, ferro magnetic atoms like iron, nickel are great at being and creating magnetic fields due to their ability to change from non magnetic to magnetic quickly and with different ways from inducing as in electromagnetic coils forcing atoms spinning differently to spin the same direction or changing the north south alignment. you can take a iron pipe and hit it with a hammer and after enough wacks the atomic structure will be disrupted and all the atoms line up in tightly compacted lines like grains in wood creating a stronger magnetic pull than if it was just a iron pipe. I hope that helps I like metaphors for understanding those kinds of concepts I hope that's helped.

The blackbody radation emmitted from a furnace peaks at a wavelength of 1.9 x 10^-6 m (0.0000019 m). what is the temperature ins
krek1111 [17]

Answer:

Temperature, T = 1542.10 K

Explanation:

It is given that,

The black body radiation emitted from a furnace peaks at a wavelength of, \lambda=1.9\times 10^{-6}\ m

We need to find the temperature inside the furnace. The relationship between the temperature and the wavelength is given by Wein's law i.e.

\lambda\propto \dfrac{1}{T}

or

\lambda=\dfrac{b}{T}

b = Wein's displacement constant

\lambda=\dfrac{2.93\times 10^{-3}}{T}

T=\dfrac{2.93\times 10^{-3}}{\lambda}

T=\dfrac{2.93\times 10^{-3}}{1.9\times 10^{-6}\ m}

T = 1542.10 K

So, the temperature inside the furnace is 1542.10 K. Hence, this is the required solution.
