The correct answer is D. All the above.
Nature plays an important role in the launch of a satellite because the satellite is launched into space by a rocket, which is powered by fuel that is derived from natural resources. The earth’s gravity reduces the speed of a satellite by 32 km per second because the satellite is constantly falling towards the earth. The gravitational force relents as the satellite climbs higher because the earth’s gravity is weaker at higher altitudes.
Here is a more detailed explanation of each option:
- Option A: Nature plays an important role in the launch of a satellite.
The satellite is launched into space by a rocket, which is powered by fuel that is derived from natural resources. The fuel is burned to create thrust, which pushes the rocket upwards. The rocket also has fins that help to stabilize it in flight.
- Option B: The earth’s gravity reduces the speed of a satellite by 32 km per second.
The satellite is constantly falling towards the earth. The force of gravity pulls the satellite towards the earth, and the satellite’s speed increases as it falls. However, the satellite is also moving sideways, and this sideways motion keeps the satellite from falling directly to the earth. The satellite will continue to fall towards the earth, but it will also continue to move sideways. This sideways motion will eventually cause the satellite to orbit the earth.
- Option C: The gravitational force relents as the satellite climbs higher.
The earth’s gravity is weaker at higher altitudes. This is because the earth is not a perfect sphere. The earth is slightly flattened at the poles, and this flattening causes the earth’s gravity to be weaker at higher altitudes.
As the satellite climbs higher, the earth’s gravity becomes weaker. This means that the satellite does not need to travel as fast to stay in orbit. The satellite’s speed will decrease as it climbs higher, and it will eventually reach a point where it is moving slowly enough to stay in orbit.
