To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.
The equation that meets these parameters is given by
Where,
c = Speed of light
f = Frequency
Our values are given as
velocity of light in free space
f = 2Hz
Replacing we have that
Therefore the correct answer is B.
The electrical charge is neutral. I hope this helps!
The answer is: Mouse/Herbivore.
First organism is always a producer (plant) such as grass.
The 2nd organism is the first level or primary consumer. Ex. Mouse - It eats the producer, so it is a herbivore.
'a', 'b', and 'c' are all reasonable statements.

Explanation:
According to the Third Kepler’s Law of Planetary motion<em> </em><em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.
</em>
In other words, this law states a relation between the orbital period 
of a body (moon, planet, satellite) orbiting a greater body in space with the size 
of its orbit.
This Law is originally expressed as follows:
(1)
Where;
is the Gravitational Constant and its value is 
is the mass of Mars
is the semimajor axis of the orbit the spacecraft describes around Mars (assuming it is a <u>circular orbit </u>and a <u>low orbit near the surface </u>as well, the semimajor axis is equal to the radius of the orbit)
If we want to find the period, we have to express equation (1) as written below and substitute all the values:
(2)
(3)
(4)
Finally:
This is the orbital period of a spacecraft in a low orbit near the surface of mars
