Answer:
<em>A. a shooting star:-</em>
<em> Definitely we can't find a shooting star.</em>
<em>B. Extremely high temperatures :-</em>
<em>The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. </em>
<em>C. Clouds:-</em>
<em>As the troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. Air gets colder as one rises through the troposphere.Therefore the clouds are present in the troposphere.</em>
<em>D. The ionosphere:-</em>
<em>The of region ionosphere that includes the thermosphere and parts of the mesosphere and exosphere</em>
<em></em>
<em>Therefore the answer is C. Clouds</em>

Answer:
The EMF of the batteries connect in series in the circuit is 12 V.
Explanation:
Given;
two batteries, each is 6 V
The EMF of the batteries connect in series in the circuit is calculated as sum of the voltage of the two batteries since they are connected in series.
EMF = V₁ + V₂
EMF = 6V + 6V
EMF = 12 V
Therefore, the EMF of the batteries connect in series in the circuit is 12 V.
