how do the patterns of diffracted light from the bulb and glowing hydrogen tube differ in appearance?

1 answer:

4 0

<span>Light given off from a hot object, in this case an incandescent bulb containing a hot filament, emits colors that appear smooth and continuous in wavelength, producing a bell curve. By contrast a hydrogen tube emit colors at different places on the spectrum, rather than continuously. For a white light, green, red, and blue must emit.</span>

An overseas flight leaves New York in the late afternoon and arrives in London 8.50 hours later. The airline distance from New Y

Evgesh-ka [11]

Answer:

v = 658.82 km/h

Explanation:

The distance between New York and London is $5.6\times 10^3\ km$

Time taken from New York to London is 8.5 hours

We need to find the average speed of the plane.

Total distance covered divided by the total time taken is equal to the average speed of an object. So,

$v=\dfrac{d}{t}\\\\v=\dfrac{5.6\times 10^3\ km}{8.5\ h}\\\\v=658.82\ km/h$

So, the average speed of the plane is 658.82 km/h.

How many grams do 3.6 x10^20 atoms of silicon weigh?

creativ13 [48]

First, we divide the number of atoms of silicon given in the problem above by Avogadro's number 6.6022 x10^23. This will give us the number of moles of silicon. Then, we multiply the number of moles by the molar mass of silicon.
number of moles = (3.6 x 10^20 atoms/6.022x10^23 atoms) = 5.97x10^-4 moles
Then, multiplying by the molar mass
(5.97x10^-4 moles)(28.0855 g/mol) = 0.017 grams
