klio [65]

Answer:

The correct answer is - C.  Increasing the concentration increases the reaction rate.

Explanation:

In the given question the data with change in different factors affect the rate of reaction differently as it alters the time it takes to complete reaction:

Conditions                            Reaction Time

Original                                  10 seconds

Higher concentration            5 seconds

Higher temperature              5 seconds  

Metal added                           5 seconds

As it is given above, time is decreased in each condition including in the case of increasing the concentration of the reactants which means the rate of reaction increases as well.

Answer:

The wavelength of the radio wave is 3.003 m.

The energy of the radio wave is 6.6194\times 10^{-26} J.

Explanation:

Frequency of the radio waves, ν = 99.9 MHz = 99.9\times 10^6 Hz

Wavelength and frequency are related to each other by realtion:

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

\lambda = Wavelength of the wave

c = speed of the light

ν = Frequency of the wave

\lambda =\frac{3\times 10^8 m/s}{99.9\times 10^6 s^{-1}}=3.003 m

The wavelength of the radio wave is 3.003 m.

The energy of the electromagnetic wave is given by Planck's equation:

E=h\times \nu

h = Planck's constant = 6.626\times 10^{-34} Js

The energy of the radio wave with 99.9 MHz frequency will be:

E=6.626\times 10^{-34} Js\times 99.9\times 10^6 s^{-1}

E = 6.6194\times 10^{-26} J

The energy of the radio wave is 6.6194\times 10^{-26} J.
