Answer:
Explanation:
In this case we will use the Bohr Atomic model.
We have that:
We can calculate the centripetal force using the coulomb formula that states:
Where K=
and r is the distance.
Now we can say:
The mass of the electron is = Kg
The charge magnitud of an electron and proton are=
Substituting what we have:
[/tex]
so:
Answer:
greater than 0.10
Explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the statistic, is the mean, is the standard deviation and n is the size of the sample.
We have that:
We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.
z = 0.45 has a pvalue of 0.6736
1 - 0.6735 = 0.3264
So our pvalue is 0.3264, which is greater than 0.10.
So the correct answer is:
greater than 0.10
From what is known in the law of reflection, the angles of the incident light that are not polarized and the polarized angle are equal, so that physical relationship can be written as
Where
= Angle of polarized light with the normal
n = Refractive Index of the Glass
Our value of the Angle is 54.2°, then
n = tan 54.2
n = 1.39
The correct answer is B.
Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of sphere = 2000 kg
= Mass of other sphere = 2.1 kg
r = Distance between spheres
Force of gravity is given by
The gravitational force is
The gravitational force is
