1) Force is a quantity that is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N." To say "10.0 N" means 10.0 Newton of force. One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. 2) The Principle of Moment states that when a system is in equilibrium the sum of its CLOCKWISE MOMENTS equals the sum of its ANTICLOCKWISE MOMENTS. Some examples where moments (turning effect) are applied involve levers, like seesaws, opening and closing doors, nutcrackers, can openers, and crowbars. 3) the size of the force applied.
the perpendicular distance from the pivot to the line of action of the force. 4) The principle of moments states that when in equilibrium the total sum of the anti clockwise moment is equal to the total sum of the clockwise moment. When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out. 5) Force is equal to mass times acceleration. Force is measured in Newtons. You can use the force equation to also find the mass or acceleration of an object. To calculate the net force acting on an object, it helps to draw a free body diagram.
for self pollination, pollen grains are transferred to the stigma of another plant on the same species while on cross pollination is transferred to the stigma of another plant on a different species of plant.
Bacteria recycle matter in an ecosystem through breaking down of the organic debris.
<h3>What is decomposition?</h3>
Decomposition is defined as the break down of dead organic matter in nature by microorganisms such as bacterias thereby releasing elements such as nitrogen that can be reused again.
Bacterias, protozoa and some fungi are known as decomposers in the food chain of an ecosystem which recycles elements found in dead organic matter by breaking them down.
