The work function for silver is 4.73 eV. (a) Convert the value of the work function from electron volts to joules.
pogonyaev

Answer:

W=7.56\times 10^{-19}\ J

Explanation:

Given that,

The work function for silver is 4.73 eV.

We need to find the value of the work function from electron volts to joules.

We know that,

1\ eV=1.6\times 10^{-19}\ J

For 4.73 eV,

4.73\ eV=1.6\times 10^{-19}\times 4.73\\\\=7.56\times 10^{-19}\ J

So, the work function for silver is 7.56\times 10^{-19}\ J.

Countries create quotas and tariffs to increase the volume of trade with their neighbors.
Svetach [21]

Oooooo, that statement is not true.  Countries create quotas and tariffs to <em>LIMIT</em> the volume of trade with other countries, including their neighbors.

If we put negative charge between two similar positive charges then what is it's equilibrium? And how?​
Gnesinka [82]

Your question has been heard loud and clear.

Well it depends on the magnitude of charges. Generally , when both positive charges have the same magnitude , their equilibrium point is towards the centre joining the two charges. But if magnitude of one positive charge is higher than the other , then the equilibrium point will be towards the charge having lesser magnitude.

Now , a negative charge is placed in between the two positive charges. So , if both positive charges have same magnitude , they both pull the negative charge towards each other with an equal force. Thus the equilibrium point will be where the negative charge is placed because , both forces are equal , and opposite , so they cancel out each other at the point where the negative charge is placed. However if they are of different magnitudes , then the equilibrium point will be shifted towards the positive charge having less magnitude.

Thank you
