A geostationary satellite moves continuously in its orbit due to the gravity applied by the Earth on the satellite. Gravity keeps the satellite in orbit, and the centrifugal force generated by its motion balances this gravitational pull, allowing the satellite ...

A sudden drop in the reading of the barometer indicates that the weather will be stormy. This drop signals a decreasing atmospheric pressure associated with stormy weather conditions, including precipitation, strong winds, and turbulent weather patterns.
We slip on muddy roads due to lack of friction. Muddy surfaces have reduced frictional force between our shoes and the ground, causing slipping. Option A (Gravitational force) and B (Relative velocity) aren’t directly responsible, while option D (Excess of ...
The pressure inside the soap bubble is less than atmospheric pressure. Surface tension of the soap film creates a pressure slightly higher than outside, but still less than atmospheric pressure. This pressure difference keeps the bubble stable. Therefore, the correct ...
Water boils at temperatures below 100°C at high altitudes because atmospheric pressure decreases. With reduced pressure, water’s boiling point lowers. Gravity’s effect and mountain winds don’t significantly impact boiling point. Therefore, the correct explanation is the decrease in atmospheric pressure.
