Question 22 A VHF television station assigned to channel transmits its signal using radio waves with a frequency of . Calculate

aleksklad [387]

The question is incomplete, here is the complete question:

A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.

Answer: The wavelength of the radio waves is 4.54 m

<u>Explanation:</u>

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light

c = speed of light = $3\times 10^8m/s$

$\nu$ = frequency of light = $66.0MHz=66.0\times 10^6s^{-1}$

Putting the values in above equation, we get:

$\lambda=\frac{3\times 10^8m/s}{66.0\times 10^{6}s^{-1}}=4.54m$

Hence, the wavelength of the radio waves is 4.54 m

In fission, a ________ _________ is one where a neutron imbeds itself in the nucleus of a U-235 atom causing it to break apart.

SVEN [57.7K]

a. chain reaction

Explanation:

In a fission, a chain reaction is one where a neutron embeds itself in the nucleus of an U-235 atom and causes it to break apart. After this, more neutrons are created. The neutrons carry on the cycle by starting the fission process over and over again.

Chain reactions typifies most nuclear reactions taking place in the nucleus of an atom.

They are repeated loops that takes place until an atom reaches it state of stability.

They are not exclusive to fission reactions alone.
Chain reactions also takes place during nuclear fusion
In fusion two atoms combines to produce a single nuclide.
The steps goes on and on
This why the sun keeps burning and bursting with energy

Butterflies are cold-blooded and need the light from the sun to warm the muscles they use to fly. Not only do butterflies like the sun, the plants the they thrive on need full direct sun. Most plants need at least 8 hours of sunlight to bloom properly and provide enough nectar.

The equation below represents the combination of gaseous atoms of non-metal X and of hydrogen to form gaseous X2He6 molecules. 2

vichka [17]

Answer:

D +405.0kJ mol-¹

Explanation:

Since bond energy is the energy required to break a bond, the energy of dissociation of X₂H₆ = +2775 kJmol⁻¹.

Since there is one X-X bond and six X-H bonds,

Bond energy of one X-X bond + Bond energy of six X-H bonds = energy of dissociation of X₂H₆.

Since bond energy of one X-H bond = 395 kJ mol⁻¹, then

Bond energy of one X-X bond + Bond energy of six X-H bonds = energy of dissociation of X₂H₆

Bond energy of one X-X bond + 6 × one X-H bond = +2775 kJmol⁻¹.

Bond energy of one X-X bond + 6 × 395 kJ mol⁻¹ = +2775 kJmol⁻¹.

Bond energy of one X-X bond + 2370 kJ mol⁻¹ = 2775 kJmol⁻¹

Bond energy of one X-X bond = 2775 kJmol⁻¹ - 2370 kJ mol⁻¹

Bond energy of one X-X bond = +405 kJmol⁻¹
