why do we slip on wet floor

We require friction for walking or running or driving, that is, the surface that we think of as non-slippery are the ones that provide some friction to our motion. Liquids, when spread over a surface, reduces the friction that surface can offer to another surface. This happens due to low shear of water and many other liquids. Because of this the two surfaces do not come in contact with each other at as many points as two surfaces without any liquid would. ...

why do we need to celebrate valentines day

You get rejected and drown your entire day in sorrows because you feel not good enough for the guy you asked out.

Poop-eating has got to be one of the most disgusting habits of dogs. Why do some dogs eat poop? How can you stop your dog from eating poop?

 why do palm tree leaves turn yellow

why do palm tree leaves turn yellow

Nitrogen deficiency can cause yellowing (chlorosis) of the older leaves on palms. Controlled-release fertilizer of 18-6-12 (N-P-K) to replace nitrogen is recommended to correct the imbalance. Iron deficiency, caused by a lack of soil aeration and by planting palms too deeply, can also cause yellow leaves. This yellowing tends to occur most often on younger leaves. Chelated iron rather than iron sulphate added to the soil can help the problem to some extent, but the underlying problem in cultivation must be corrected. A lack of magnesium can also cause yellowing of both older and younger leaves, as well as darkening (necrosis) of leaf tissue. It can be difficult to treat. Fertilizer with magnesium micronutrient added, such as 8-2-12+4Mg with additional dolomite is suggested to correct the

 why do priests wear purple during advent

why do priests wear purple during advent

In the Roman Catholic Church, the color a priest wears when celebrating Mass coincides with the liturgical color of the season, the colors that the Church has specified for a particular period or day within the Churchвs calendar. The priestвs outer robe--the chasuble--and supplemental vestments, such as the stole, mirror the colors that adorn the church. Currently, the Church designates black, green, red, purple and white for its liturgical calendar, with rose as an optional sixth color. Each color has retained some sort of symbolic meaning to the Church. Black has long been the symbol of death.
