Mercury is more dense than water.
The meniscus, which is creaded by adhesion of the liquid particles to the surface of the container. Water meniscus domes upwards - the water has greater bonding to its own molecules; Mercury meniscus domes downwards.
The meniscus of water curves downwards due to its adhesive properties, which cause water molecules to be more attracted to the polar surface of the container than to each other. This leads to a concave shape as the water molecules cling to the sides. In contrast, mercury has strong cohesive forces between its molecules, which dominate over adhesive forces with the container, resulting in a convex meniscus as the mercury pulls itself together rather than spreading out.
the rocket is pushing water downwards which means that the water pushes the rocket upwards very hard that it can overcome gravity and fly.
Boiling takes place and it leads to the movement of hot water upwards and the movement of cold water downwards.
Two forces that act on an object in water are buoyant force, which pushes the object upwards, and gravity, which pulls the object downwards.
It is from Lin Yutang writings "The Importance of Living", 1937. He talks about the duty of the adult male toward his parents and about the process of aging. It is a Chinese tradition the firstborn male has a duty to take care of his aging parents. It is considered the gravest of sins for those that do not fulfill their duties. Elders are respected in the Chinese culture. The quote is "Water flows downwards and not upwards"
Water flows downwards due to Earth's gravity.
An object floats in water when the buoyant force acting upwards on the object is greater than the weight of the object pulling it downwards. This is due to the principle of buoyancy, where the volume of water displaced by the object is equal to the weight of the object.
The hot air is less dense so cold air rushes in to shove it upwards like a cork on water.
Phloem transports sugars and organic nutrients from the leaves where they are produced through photosynthesis, down to other parts of the plant for growth and storage. This movement is known as translocation and generally occurs in a downward direction, from source (leaves) to sink (other parts of the plant).
The paired fins, pectoral and pelvic, act as hydroplanes and control the pitch of the fish, causing it to swim downwards or upwards according to the angle to the water at which they are held by their musclesalso the swim bladder - Novanet
