Answer:
A solution in which the maximum amount of solvent has been dissolved
Explanation:
For example, 36g of salt in 100g of water.
Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
Answer:
<em>By showing that changing the frequency of light causes the emission of faster electrons.
</em>
Explanation:
<em>The photoelectric effect happens when light strikes a metal surface causing the emission of electrons from it (photoelectrons).
</em>
<em>If you increase the intensity of the light you get, as acresult, more electrons emitted but their kinetic energy does not increase.
</em>
<em>If you increase the frequency of the incident light the number of photoelectrons emitted does not increase while the velocity, and so their kinetic energy, increases...the emitted electrons are more...energetic!
</em>
<em>
</em>
<em>This can be explained considering the incident light as a shower of particle-like packets of energy (photons); if you increase the intensity you simply increase the number of packets (all with the same energy) hitting the metal; these can be used by a lot of electrons to escape.
</em>
<em>On the other hand if you increase the frequency the number of packets remains the same (emitting fewer electrons perhaps) but the energy carried by each of them increases.
</em>
<em>Each packet carries an energy directly proportional to the frequency.</em>

Well according to the equation that relates the two.
F = M • a
A = acceleration = velocity/time
Velocity = displacement/time.
Assuming that there is no change in the displacement, in other words, one is pushing an object in one direction only.
Then distance can equal displacement.
Thus to keep pushing on an object in a straight line at a certain acceleration, maintaining the same speed over each time interval. You need to be applying a constant force.
The greater the distance that you need to push the object for at a specific acceleration the greater the force.
