Answer: a) 8.2 * 10^-8 N or 82 nN and b) is repulsive
Explanation: To solve this problem we have to use the Coulomb force for two point charged, it is given by:

Replacing the dat we obtain F=82 nN.
The force is repulsive because the points charged have the same sign.
The difference between sublimation and condensation is that
Sublimation is used to in a separation technique to separate sublime substance from a mixture while condensation is the
is the process where water vapor becomes liquid
<h3>What is separation technique?</h3>
This technique is used in chemistry to separate two or more constituents from a mixture
In conclusion, sublimation differs from condensation because sublimation is used to in a separation technique to separate sublime substance from a mixture while condensation is the
is the process where water vapor becomes liquid

Light travels in waves AND in bundles called "photons".
It's hard to imagine something that's a wave and also a bundle.
But it turns out that light behaves like both waves and bundles.
If you design an experiment to detect waves, then it responds to light.
And if you design an experiment to detect 'bundles' or particles, then
that one also responds to light.
Answer:
F = MA
Explanation:
OP you didn't give us any examples, but force equals mass times acceleration is Newton's First Law.
Dropping a ball (mass) from the top of a building can show gravity, a form of acceleration.
