Question

Give reason for the following (i Buildings have wide foundations for safety. (ii) A pin sinks in water while it floats on honey

Answer 1

1.because if surface area increased pressure decrease so building have wider foundation
2.because it density is high than water
but honey density is higher than pin
mark it brainliest

Answer 2

ii) Density of pin is more than that of water so it sinks and density of honey of honey is more than that of pin so the pin floats in honey.
i) A building exerts a lot of force on ground to reduce the pressure on ground they have a wide foundation.
