Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which

notka56 [123]

Answer:

$a=5.66*10^{23} \frac{m}{s^2}$

Explanation:

In this case we will use the Bohr Atomic model.

We have that: $F=m*a$

We can calculate the centripetal force using the coulomb formula that states:

$F=k*\frac{q*q'}{r^2}$

Where K= $9*10^9 \frac{Nm^2}{C}$

and r is the distance.

Now we can say:

$m*a=k*\frac{q*q'}{r^2}$

The mass of the electron is = $9.1*10^{-31}$ Kg

The charge magnitud of an electron and proton are= $1.6*10^{-19}C$

Substituting what we have:

$[tex]a=\frac{9*10^{9}*(1.6*10^{-19} )*(2(1.6*10^{-19} ))}{9.1*10^{-31}*(2.99*10^{-11})^2 }$ [/tex]

so:

$a=5.66*10^{23} \frac{m}{s^2}$

Which of these results from destructive interference?

Mazyrski [523]

Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.
