3. what is the wavelength (in meters) of the electromagnetic carrier wave transmitted by the
sports fan radio station at a frequency of 640 x 109 hz?
with work

The wave with the frequency of 640 × 10⁹ Hz have 5 × 10⁻⁴ m wavelength.

Explanation:

Given data:

Frequency of wave = 640 × 10⁹ Hz

Wavelength = ?

Solution:

speed of light = 3 × 10⁸ m/s

Formula:

wavelength =Speed of light / frequency

λ =  c / f

Now we will put the values in formula.

λ =   3 × 10⁸ m/s /  640 × 10⁹ Hz

Hz = s⁻¹

λ =   3 × 10⁸ m/s /  640 × 10⁹ s⁻¹

λ =  5 × 10⁻⁴ m

The wave with the frequency of 640 × 10⁹ Hz have 5 × 10⁻⁴ m wavelength.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

50.23 i believe is correct but don't quote me on that.
