A volcano erupted on an island. The entire plant community was destroyed and the island was covered with grey ash. Slowly, liche

ns and mosses started growing on the island. They helped in the process of soil formation and later other plants started growing too.

Answer:

There are several kinds of plants who grow and thrive near volcanic locations. For example coffee, grape vines, moss and the rare Hawaiian argyroxiphium, or "silversword." These plants grow and survive using the nutrients from the ashes of the volcanic eruptions along with cooled lava.

Mosses and Lichens form a protective layer over the land which helps it to retain water inside it, rather than drying out which is the case in volcanic sites. Therefore, the retained water helps the land to form and become appropriate for other plants to grow as well.

When landing after a spectacular somersault, a 35.0 kg gymnast decelerates by pushing straight down on the mat. calculate the fo
Sliva [168]

The deceleration experienced by the gymnast is the 9 times of the acceleration due to gravity.

Now from Newton`s  first law, the net force on gymnast,

F_{net} =F-W=ma

Here, W is the weight of the gymnast and a is the acceleration experienced by the gymnast (9\times g acceleration due to gravity)  

Therefore,

F= ma+W OR F=ma+mg=m(g+a)

Given m = 30 kg anda=9\times g=9\times 9.8 m/s^{2} =88.2 m/s^{2}

Substituting these values in above formula and calculate the force exerted by the gymnast,  

F=(40 kg) (88.2 m/s^{2} +9.8 m/s^{2} )

F=3.537\times10^{3}N
