4) Capital gain is the benefit obtained on selling a capital asset and if we face loss on selling the capital asset it results in capital loss. Capital assets are like stock, bonds, properties, etc.
Answer:
The hydrostatic force of 313920 N is acted on each wall of the swimming pool and this force is acted at 1 m from the ground. The hydrostatic force is quadruple if the height of the walls is doubled.
<u>Explanation:</u>
To calculate force on the walls of swimming pool whose dimensions are given as <em>8-m-long, 8-m-wide, and 2-m-high</em>. We know that formula for hydrostatic force is
, we know ρ=density of fluid=1000
,
g=acceleration due to gravity=9.81
, h=height of the pool=2 m and l=length of the pool=8 m.
hydrostatic force on each wall=
= 313920 N.
<em>The distance at which hydrostatic force is acted is half of the height of the swimming pool.
</em>
At 1 m from the ground this hydrostatic force is acted on each wall.
The force is <em>quadruple if the height of the walls of the pool is doubled</em> this is because, the<em> height is doubled and taken as h=4 m</em> and substitute in the equation =
=
= 1255680 N. This is 4 times 313920 N.
Answer:
paleopathology
Explanation:
Paleopathology is a relatively new discipline.
Paleopathology is mainly the study of the traces of disease left in fossils and mummies. It also includes the study of the signs related to the disease in archaeological objects.
