Latest information on quantum dots.

1 answer:

7 0

Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms. They are used as labels for imaging molecules because of their very narrow fluorescence, brightness, and resistance to photobleaching.

This is the most recent information I could find.

I hope this helps:)

You place a small air cart on a 4.00 m air track and set it into motion with a speed of 0.75 m/s. Due to very good elastic bumpe

san4es73 [151]

Answer:

6 seconds

0.167 Hz

Explanation:

Distance = 4 m

Velocity = 0.75 m/s

Period is given by

$T=2\times Distance\times Velocity\\\Rightarrow T=2\times 4\times 0.75\\\Rightarrow T=6\ s$

The period of the motion is 3 seconds

Frequency is given by

$f=\frac{1}{T}\\\Rightarrow f=\frac{1}{6}\\\Rightarrow f=0.167\ Hz$

The frequency of the motion is 0.33 Hz
