How did the ideas of einstein and freud contribute to a sense of uncertainty?

Ipatiy [6.2K]

Einstein's Theory of Relativity was a theory which carried about hesitation in Newton's gravity which was measured as an important part of science. Which brings one to query what we detect as being factual.
Freud's thoughts about the subliminal questions one's own mind to what we have faith in. Is a dream just a dream, or is it your subliminal trying to tell you a little? It brought about a feeling of being ignorant of what is going on in your own mind.
These and maybe other bring persons to doubt about the world about them and within themselves.

Vf=V0+at solve for a

dangina [55]

Answer:

See below

Explanation:

vf = vo + at subtract vo from both sides

vf - vo = at now divide both sides by t

(vf-vo) / t = a

The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660 . A beam of white light in

Alinara [238K]

Answer:

The angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°

Explanation:

Given:

Refractive index for red light $n _{1} = 1.620$

Refractive index for violet $n' _{1} = 1.660$

Refractive index for air $n_{2} = 1$

Incident angle $\theta _{1} =$ 28.30°

According to the snell's law,

$n_{1} \sin \theta _{1} = n_{2} \sin \theta _{2}$

For red light,

$1.620 \times \sin 28.30 = 1 \sin \theta _{2}$

Where $\theta _{2} =$ transmitted angle for red light

$\theta _{2} =$ 50.18°

For violet light,

$1.660 \times \sin 28.30 = 1 \sin \theta' _{2}$

Where $\theta' _{2} =$ transmitted angle for violet light

$\theta' _{2} =$ 51.9°

Angular separation between red and violet light is given by,

$\theta ' _{2} - \theta _{2} = 51.9 -50.18 =$ 1.72°

Therefore, the angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°

A 6.89-nC charge is located 1.76 m from a 4.10-nC point charge. (a) Find the magnitude of the electrostatic force that one charg

iogann1982 [59]

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:

$F=\frac{k*q1*q2}{d^{2}}$

Replacing the dat we obtain F=82 nN.

The force is repulsive because the points charged have the same sign.
