Answer: bismuth and nitrogen, because they have the same number of valence electrons

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.

The number of valence electrons in Bismuth and nitrogen are 5 and thus thus they will show similar chemical properties and thus belong to the same group.

The atomic masses of elements in a group will differ drastically.

The group number has got nothing to be the isolation year.

Thus bismuth and nitrogen belong to same group because they have the same number of valence electrons

The Capacitive reactance of a 0.094uF capacitor when a frequency of 25kHz is applied is lus 68 Ohms 0.68 Ohms luf

Nana76 [90]

Answer:

Capacitive reactance of the capacitor is 68 ohms

Explanation:

It is given that,

Capacitance, $C=0.094\ \mu F=0.094\times 10^{-6}\ F$

Frequency, $f=25\ kHz=25\times 10^3\ Hz$

Capacitive reactance is given by :

$X_C=\dfrac{1}{2\pi fC}$

$X_C=\dfrac{1}{2\pi 25\times 10^3\times 0.094\times 10^{-6}}$

$X_C=67.72\ \Omega$

$X_C=68\ \Omega$

So, the capacitive reactance of the capacitor is 68 ohms. Hence, this is the required solution.

Explanation:

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. ... This means that some individuals would survive and be able to reproduce and generate more offspring.

A circular loop of wire lies in the plane of your screen. An increasing magnetic field (produced by another source) points out o

Rashid [163]

Answer:

clockwise direction

Explanation:

Direction of induced current is found with the help of Lenz's law . According to this law , the direction of induced current is such that it tries to neutralize or oppose the reason which creates this current .

In the given case , magnetic field is towards the viewer of the screen and it is increasing , so the induced current will have to create magnetic field in opposite to it . It means magnetic field will be created towards the screen into it . So the current will be induced in clockwise direction . This current will create magnetic field into the screen which will oppose increasing magnetic field out of screen .
