For a storm to be a blizzard, the wind must be at least 35 miles per hour. This is just one criteria for considering a storm to be a blizzard. The wind speed of 35 miles per hour should reduce the visibility to less than 400 meters. The last criteria is that the storm must continue for a time frame of at least 3 hours.

Answer:

The magnitude of the angular acceleration ∝ = $\frac{rxF}{2.8[tex]r^{2}$ }[/tex]

Explanation:

The angular acceleration ∝ is equal to the torque (radius multiplied by force) divided by the mass times the square of the radius. The magnitude of angular acceleration ∝ will have the equation above but we have to replace the mass in the equation by 2.8kg as stated.

PLEAS HELP.

koban [17]

<span>A: put an atom on a poster in the exhibit
   Good luck. The poster itself is made of trillions of trillions of trillions
   of atoms. You could not see the extra one any easier than you could
   see the ones that are already there, and even if you could, it would be
   lost in the crowd.

B: use a life size drawing of an atom
   Good luck. Nobody has ever seen an atom. Atoms are too small
   to see. That's a big part of the reason that nobody knew they exist
   until less than 200 years ago.

D: set up a microscope so that visitors can view atoms
   Good luck. Atoms are way too small to see with a microscope.

</span><span><span>C: Display a large three dimensional model of an atom.
  </span> </span>Finally ! A suggestion that makes sense.
   If something is too big or too small to see, show a model of it
   that's just the right size to see.

A) See ray diagram in attachment (-6.0 cm)

By looking at the ray diagram, we see that the image is located approximately at a distance of 6-7 cm from the lens. This can be confirmed by using the lens equation:

$\frac{1}{q}=\frac{1}{f}-\frac{1}{p}$
