Given:
Radius of earth,
Radius of of orbit,
mass of earth,
Formula used:
By Kepler's third law,
Solution:
Using the given values in above mentioned formula:
Therefore, time period of satellite is
(a) The block has a weight of (27.0 kg) <em>g</em>, and the normal force of the surface pushing upward on the block has the same magnitude, so that static friction exerts a maximum force of
<em>µ</em> (27.0 kg) <em>g</em> = 70.0 N
where <em>µ</em> is the coefficient of <u>static</u> friction. Solving for <em>µ</em> gives
<em>µ</em> = (70.0 N) / ((27.0 kg) <em>g</em>) ≈ 0.265
(b) As it's moving, the block still has the same weight and thus feels the same normal force, (27.0 kg) <em>g</em>. In order to move at a constant speed, kinetic friction must exert the same force as the push, so
<em>µ</em> (27.0 kg) <em>g</em> = 64.0 N
where <em>µ</em> is now the coefficient of <u>kinetic</u> friction. Solve for <em>µ</em> :
<em>µ</em> = (64.0 N) / ((27.0 kg) <em>g</em>) ≈ 0.242

Because when plants and animals die the decomposers recycle the nutrients making then available again for the growth of plants or animals. So without decomposers the essential nutrients needed for the growth of plants and animals cannot be replaced.
