<span>A portion of the atmosphere that becomes warmer than surrounding air will expand and rise. The warmer atmosphere the more space between the molecules. Therefore, warmer atmosphere </span><span>expands to allow more space for the molecules. Cool air on the other hand, contracts because the molecules in cool air need less space.</span>
To calculate the force between two negative charges, we use the formula which is given by the Coulomb`s Law as
Here, 
and
are the charges on the pith balls, r is the separation between the charges and k is constant and its value is 
.
Given 
and 
.
Substituting these values in above formula we get,
Thus, the repulsive force between two pith balls is 
.

Determine the parametric equations
Differentiate with respect to t
Let t = 1 (i.e )
To solve for x, y and z, we make use of:
This implies that:
So, we have:
By comparison:
Divide by i
Divide by j
Divide by k
Hence, the parametric equations are:
We can determine a planet's orbital period and separation from its star using any detection method. The transit method can yield sizes, whereas the astrometric and doppler approaches can provide minimum masses.
We can calculate average density by combining the transit and doppler approaches. Numerous physical properties, including the semi-major axis, stellar mass, star radius, planet radius, eccentricity, and inclination, are calculated from these observable data. The mass of the planet is also calculated using the star's combined radial velocity readings.
List briefly the planetary characteristics that, in theory, can be detected with the present detection techniques. We can determine a planet's orbital period and separation from its star using any detection method. The transit method can yield sizes, whereas the astrometric and doppler approaches can provide minimum masses.

<span>That could be letter B: flowchart. Flowchart diagrams
can be used to easily service an electronic circuit board with ICs because they
let you see the flow of the current as you could imagine it. You can use
different shapes to further your explanation and illustration on how the
electricity flows from a source, to its medium to the switches. You could also
decide on flowcharts and be able to see where that decision leads you and you
could also try to learn different decision methods which is basically
illustrated on the chart.</span>
