The relationship between frequency and wavelength for an electromagnetic wave is
c=f \lambda
where
f is the frequency
\lambda is the wavelength
c=3 \cdot 10^8 m/s is the speed of light.

For the light in our problem, the frequency is f=1.20 \cdot 10^{13} s^{-1}, so its wavelength is (re-arranging the previous formula)
\lambda= \frac{c}{f}= \frac{3 \cdot 10^8 m/s}{1.20 \cdot 10^{13} s^{-1}}=  2.5 \cdot 10^{-5}m

Wave power can be regarded as a reliable source of energy because the ocean currents are always moving.

<h3>What can be the challenges of wave power?</h3>

Wave power is a device that can be used to convert the mechanical energy of the ocean waves into electrical energy based on the principle of conservation of energy.

The major challenges that face the use of wave power in electricity generation is the unreliability of the waves which leads to uncertainty in the quantity of power generated Also, the wave direction and direction of ocean currents all limit the amount of power generated by this method. However, in spite of challenges, it can be regarded as a reliable source of energy because the ocean currents are always moving.

A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake.
ArbitrLikvidat [17]

Answer:

L = 499 m

Explanation:

  • If we assume that the speed of sound is constant, that travels along a straight line, and that the echo is instantaneous, we can find the total distance travelled by the sound, as follows, just applying the definition of average velocity:

       \Delta x = v_{s} * t = 343 m/s* 2.91 s = 998 m

  • If we assume that the time needed to reach to the cliff, is the same used for the return travel, the length of the lake will be exactly half of the total distance calculated:

        l_{lake} = \frac{\Delta x}{2} = \frac{998m}{2} = 499 m

  • The length of the lake is 499 m.

“instrucciones” para hacer los diagramas de Lewis de un compuesto iónico y luego para uno covalente. ¿En qué se diferencian y en
Mazyrski [523]

Answer:

- Se diferencian en que en los compuestos iónicos se ceden y aceptan electrones, mientras que en los covalentes de comparten.

- Se parecen en que los enlaces son formados por medio de los electrones de valencia y que en ambos compuestos la ley del octeto se debe cumplir.

Explanation:

¡Hola!

En este caso, debemos recordar que los compuestos iónicos se dan cuando se forman enlaces iónicos en los que el elemento más electronegativo tiene la capacidad de aceptar los electrones perdidos por el elemento menos electronegativo con el fin de cumplir la ley del octeto en la que 8 electrones deben ser exhibidos en la molécula. Por otro lado, los compuestos covalentes se forman cuando los átomos comparten sus electrones de valencia con el fin de alcanzar la ley del octeto.

De este modo encontramos que se diferencian en que en los compuestos iónicos se ceden y aceptan electrones, mientras que en los covalentes de comparten.

Por otro lado, ambos se parecen en que los enlaces son formados por medio de los electrones de valencia y que en ambos compuestos la ley del octeto se debe cumplir.

¡Saludos!

Please help Which graph shows the change in velocity of an object in free fall?
dmitriy555 [2]

The graph that shows the change in velocity of an object in free fall is graph B.

<h3>What is velocity?</h3>

Velocity is the speed of a body in a specified direction.

It is also defined as the ratio of displacement and tome.

Velocity is a vector quantity.

The change in velocity of a body is known as acceleration.

The velocity of a body undergoing free fall increases by a constant value given as by the acceleration due to gravity.

The graph which depicts this change in velocity is B.

Therefore, the graph that shows the change in velocity of an object in free fall is graph B.
