The diagram shows the Earth's position relative to the Sun at different times of the year. In the northern hemisphere, the United States experiences the most direct sunlight during the summer solstice. This occurs around June 21st when the Earth's tilt causes the Northern Hemisphere to be inclined towards the Sun. At this time, the Sun's rays hit the Northern Hemisphere more directly. In the diagram, position C represents the location of the Earth during the summer solstice, where the Northern Hemisphere receives the most direct sunlight.

Commercial airline pilots primarily fly in the lower stratosphere and upper troposphere to avoid turbulence and ensure smooth flight conditions.

The troposphere is where weather phenomena and turbulence are common, so pilots seek stable conditions typically found at the boundary with the stratosphere.

The stratosphere offers stable atmospheric conditions, ideal for cruising altitudes. Reference:

*Gravitational force comparison:** Planet X has less gravity than Planet Y. - **Acceleration due to force:** The acceleration of an object is given by \( a = \frac{F}{m} \). With the same force applied, the acceleration will be higher where the gravitational pull is weaker. - **Initial acceleration:** Since Planet X has less gravity, the same force will cause the ball to accelerate more on Planet X than on Planet Y. - **Conclusion:** The ball will initially accelerate more on Planet X. **Reference:** Physics textbooks on Newton's laws of motion, principles of gravitation, and kinematics.

The early universe consisted primarily of hydrogen atoms, which began to coalesce due to gravitational attraction.

As these hydrogen atoms collected into large clouds, the gravitational force continued to draw them closer together, increasing pressure and temperature at the core.

Once the pressure and temperature were high enough, nuclear fusion ignited, forming the first stars.

This process was driven by the gravitational force, not by other forces like magnetic or momentum from the big bang. Reference:

The troposphere is the lowest layer of the atmosphere where weather phenomena, including cloud formation, occur.

Atmospheric scientists study cloud formation and other weather-related processes within this layer. Reference:
