Answer:
Since the particle 1 and 2 are on the x-axis, the 3rd particle should also be on the x-axis in order the net force on it to be zero.
Let's denote the distance between particles 1 and 3 as x. Therefore the distance between particles 2 and 3 is (0.1 - x), since the distance between 1 and 2 is 0.1 m.
Coulomb's Law states the force between charges as
The question asks that 
, so
We will take the positive root:
away from the first particle.
Explanation:
Since Fig. 21-25 is not given in the question, the exact locations are not known. However, the location of the third particle is found to be 0.036 m away from the first particle and the third particle is located between the particles 1 and 2.
Answer:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Explanation:
Materials when heated emit a continuous spectrum with all wavelengths.
Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.
When reviewing the answers, the correct one is:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
A. One substance must dissolve in another
Answer:
Answer is A) Fermi
Explanation:
Fermi is the expressive unit for nuclear sizes. Fermi = 10^-15 meter.
The part that moves are called anti-nodes. The stationary pars are nodes
