First read the introduction.
Seconds look at the pictures how to build it.
the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
Answer:
atom 2 and 3 or d is should be your answer
Explanation:
.....
a.The gas pressure will decrease.
Explanation:
If in a rigid container, the amount of gas particles and volume of the container is held constant, the pressure will decrease if the temperature is reduced.
- Gases are highly random particles and they require a high amount of kinetic energy to be in their state of matter.
- In a condition where volume of container is fixed, the amount of gas particles is fixed and the temperature reduced, the kinetic energy of the gas particles will directly reduce.
- The kinetic energy of gases is directly related to temperature.
