what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
Explain how changes in atmospheric pressure affect the height of barometer?
Pressure is
proportional to volume, if the pressure increases the volume decreases and when
the pressure decreases the volume increases , the height in the barometer is
our volume here.
