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.
If the mass of the Earth remains the same and the radius decreases by 1%, then the value of ‘g’ at the surface of the Earth will increase by will increase by 2%. This is because gravitational acceleration ‘g’ is ...
Ink comes out from a fountain pen in an aeroplane because air pressure decreases with increase in altitude. As the plane ascends, the surrounding air pressure decreases, causing the air inside the pen to expand. This expansion can force ink ...
