The work function of rubidium smaller than the work function of potassium.
<h3>How can we compare the work function of rubidium and potassium?</h3>
The work function of the films was determined photoelectrically. So we can say that which particle shows a better photoelectric effect that particle has a greater work function.
Films of rubidium were deposited on quartz substrates by evaporation at pressures of less than 10⁻¹⁰ Torr.
At 140 K the work function of rubidium was determined photoelectrically, so the work function of Rubidium was found to be (2.261 ± 0.015) eV.
And now for the potassium we can show that, At 140 K the work function of Potassium was found to be 2.3eV.
So from the above data we can conclude that,
2.26± 0.015 < 2.3
The work function of rubidium smaller than the work function of potassium.

Answer:
when a force is applied by one object to a second object, an equal and opposite force is applied back on the first object
Explanation:
Answer:
b. The current stays the same.
Explanation:
In the case given current is supplied by the battery to a bulb . Here, we should know that bulb also apply resistance to the flow of current .
Now, when an identical bulb is connected in parallel to the original bulb .
Therefore, both the resistance( bulb) are in parallel.
We know, when two resistance are in parallel , current through them is same and voltage is divided between them.
Therefore, in this case current stays same in the original bulb.
Hence, this is the required solution.
