The first three choices: a, b and c can be considered reconstruction except the last one which is letter d. I'm not really certain what reconstruction is, but judging from the patterns of the first three choices, reconstruction could mean that an inference is made after a part of an event has proved that event to be true.

two coils close to each other have a mutual inductance of 32 mh. if the current in one coil decays according to , where i0
Harlamova29_29 [7]

The EMF induced in the second coil is 43 Volts.

Michael Faraday was the first to discover electromagnetic induction back in the 1830s. Faraday discovered that moving a permanent magnet in and out of a coil or a single loop of wire caused an electromotive force, or EMF—otherwise known as a voltage—to be produced.

Changing magnetic flux results in varied currents flowing through the coil, which in turn generates its own magnetic field. This self-induced EMF opposes the change that is creating it, and the stronger the opposing EMF is, the faster the rate at which the current is changing. According to Lenz's law, this self-induced EMF will oppose the change in current in the coil, and because of its orientation, it is typically referred to as a back-EMF.

Answer:

Well, if you look up countries with the highest birth rates, also those countries poverty rates and what class the majority of the people are in then you should have a better understanding. Also, education is not passed through genes it is learned through expirience and being taught. Also being rich vs being poor probably doesn't have that big of an effect either. It is the living conditions.

You observe a star system for many weeks. The light curve does not show significant changes in brightness, but a series of spect
mariarad [96]

Based on the changes in the light curve and the behavior of the series of spectra, this is a<u> binary system. </u>

<h3>How is this is binary system?</h3>

The characteristics described are those of a binary system with the specific type of system being the spectroscopic binary system.

This is because in a spectroscopic binary system, there won't be significant changes in brightness but as a result of stars orbiting towards and then away from us, spectral features will appear as alternative absorption lines.

In conclusion, this is a binary system.

A moving freight car collides with an identical one that is at rest. If momentum is conserved, what happens to the second car af
yKpoI14uk [10]

For all elastic collisions we have

e = \frac{v_2 - v_1}{u_1 - u_2}

e = 1 = \frac{v_2 - v_1}{u_1 - u_2}

v_2 - v_1 = u - 0

also by momentum conservation we will have

m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2

since two cars are identical so we know that

m_1 = m_2 = m

u + 0 = v_1 + v_2

now by solving two equations we will have

v_2 = u

v_1 = 0

so the correct answer must be

It attains the same speed as the first car.
