Answer:

  • 4) x = 4

Explanation:

Using <u>Intersecting Chords Theorem</u>,

AB × CB = BE × BD

  • ( 4x + 2) × 8 = 9 × ( 4x )
  • 32x + 16 = 36x
  • 16 = 36x -32x (Subtract)
  • 16 = 4x (Divide both sides by 4)
  • x = 16/ 4 (Divide)
  • x = 4

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.
likoan [24]

Given :

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.

To Find :

The volume of the gas after it is heated.

Solution :

Since, their is no information about pressure in the question statement let us assume that pressure is constant.

Now, we know by ideal gas equation at constant pressure :

\dfrac{V_1}{V_2} = \dfrac{T_1}{T_2}\\\\\dfrac{3.82}{V_2}= \dfrac{204.9}{304.8}\\\\V_2 = \dfrac{304.8}{204.9} \times 3.82\\\\V_2 = 5.68 \ L

Hence, this is the required solution.

Why are only certain colors absorbed by and emitted from an atom?
zavuch27 [327]
The way I would explain it is quite difficult to understand, so this is what Google says. "The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's spectrum. The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted." I hope this helped.
