Heisenberg's Uncertainty Principle states that we cannot simultaneously measure both the position and momentum of an object bett

er than a certain accuracy. This limitation is not a consequence of imperfect technology, but is a fundamental law. It applies to all objects -- photons, electrons, baseballs, etc.. A highly monochromatic, continuous beam of laser light of wavelength 470 nm passes through an electro-optic shutter. The shutter opens and closes in a time interval of Δt = 90 ps . After passing through the shutter to what uncertainty, Δx, have the photons been localized?

For this specific problem, the photons have been localized to D<span>x = </span>0.027m uncertainty. I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.

What is the strength of an electric field that will balance the weight of a 3.3 g plastic sphere that has been charged to -7.6 n
sp2606 [1]

As the plastic sphere is charged, therefore it experience an electric force when placed in an electric fields and also experiences gravitational force acts downward so the electric force must act upward.

Let  F_{E} is electric force and F_{G} is gravitational force.

If these forces are balanced, thereforeF_{E} = F_{G}

or                                                                      \left | q \right |E=mg\\\\\ E=\frac{mg}{\left | q \right |}

Given, q=-7.6 nC=-7.6\times10^{-9} C and  m=3.3 g= 3.3\times10^{-3} kg.

Substituting these values in above equation we get,

E=\frac{3.3\times10^{-3} kg\times9.8 m/s^{2} }{7.6\times10^{-9} C}\\\\E=4.2\times10^{6} N/C

Thus, the magnitude of electric field is 4.2\times10^{6} N/C.

As the charge is negative, the electric field at the location of the plastic sphere must be pointing downward.

What distinguishes a nebula and a star?
Kryger [21]

What distinguishes a nebula and a star is that a nebula is a cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter. And a star is a<span> type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.</span>

what will be evidence of a galaxy moving toward earth? A. The galaxy has a loose, disorganized appearance b. the stars in the ga
oksano4ka [1.4K]
Choice D). is on the right track, but it's stated incorrectly.

The wavelengths of light coming from a galaxy that's moving toward us <em>are </em>
<em>shorter</em> than they were when they left the galaxy.  When we see them, they're
shorter than they should be.

(This is called a "blue shift" in the spectrum of the galaxy, because blue is the
short-wavelength end of the spectrum of visible light.  If the wavelength of some
light somehow becomes shorter, then the color of the light changes toward the
direction of blue.)

If the source of light is moving toward us, then the wavelength we see is shorter
than it should be.  If the source is moving away from us, then the wavelength
we see is longer than it should be.  The whole trick to this is knowing <u>what</u> the
wavelength of the light we see <em>should be</em> !
