Which of the following phenomena is not due to gravitational force?a)m...
Introduction:
Gravitational force is a fundamental force of nature that attracts objects with mass towards each other. It is responsible for many phenomena in the universe. However, there are certain phenomena that are not directly caused by the gravitational force.
Movement of satellites around planets:
Satellites are objects that orbit around planets, moons, or other celestial bodies. The movement of satellites around planets is primarily due to the gravitational force between the satellite and the planet. The gravitational force provides the necessary centripetal force to keep the satellite in orbit. Therefore, the movement of satellites around planets is a result of gravitational force.
Rainfall and snowfall:
Rainfall and snowfall are phenomena that occur due to the water cycle on Earth. The water cycle involves the evaporation of water from the surface, condensation of water vapor into clouds, and precipitation of water back to the surface in the form of rain or snow. While gravity does play a role in the water cycle by causing water to fall back to the surface, it is not the primary force responsible for the formation of clouds or the condensation of water vapor. Other factors such as temperature, humidity, and air pressure are involved in these processes.
Tides in oceans:
Tides are the rise and fall of sea levels caused by the gravitational forces of the Moon and the Sun acting on the Earth's oceans. The gravitational force exerted by the Moon is stronger on the side of the Earth facing the Moon, causing a high tide. On the opposite side of the Earth, there is also a high tide due to the centrifugal force resulting from the Earth-Moon system's rotation. The gravitational force of the Sun also contributes to the tides, although to a lesser extent. Therefore, tides in oceans are primarily caused by the gravitational force.
Conclusion:
In conclusion, all the given phenomena - movement of satellites around planets, rainfall and snowfall, and tides in oceans - are due to the gravitational force. Therefore, the correct answer is option 'D', which states that all of these phenomena are caused by gravitational force.
