We know that plants take nutrients from soil and thus exhaust the soil of most of the nutrients with passage of time. Thus, continuous plantation of crops in the field results in loss of fertility for the soil. The soil may become infertile in the long run.

The SI unit of pressure is Pascal (represented as Pa) which is equal to one newton per square metre (N/m-2 or kg m-1s-2). Interestingly, this name was given in 1971. Before that pressure in SI was measured in newtons per square metre.

Sprinkler system
In this system, there are perpendicular pipes with rotating nozzles on top. These pipes are joined to the main pipeline. Water flows through main pipeline under pressure by a pump. Water escapes from the nozzles & reaches the field.

Suppose two forces of same magnitude F are acting on an object in the same direction. In this case the forces adds up to give the net force. Thus, the net force on the object is given as:
F = F + F = 2 F.

The reasons why some of the fibres are called synthetic is because man has prepared them by using chemicals. These are made of small units that join together to form long chains. Some of the examples of synthetic fibres are nylon, rayon, acrylic, polyester etc.

Contact forces : Force that arises with the contact of 2 or more objects involved. Examples : Muscular force and Frictional Force
Non-contact forces: Forces that arise without the contact of 2 or more objects involved. Examples: Magnetic Force, Electrostatic Force, Gravitational force.

Synthetic fibres melt very soon on heating. If the clothes catch fire, it can be disastrous. The fabrics melt and stick to the body of a person wearing it. We should therefore not wear synthetic clothes while working in the kitchen.

Contact forces : Force that arises with the contact of 2 or more objects involved. Examples : Muscular force and Frictional Force
Muscular force is the type of force wherein we use our physical strength to change the state of motion of an object. Eg: Man pushing a car, Bullocks pulling a cart of load, Cycling, Weight Lifting
Frictional Force is a force that acts on all moving objects by the surface which it is in contact with. Eg: A ball rolling on the ground encounters friction by the ground surface and it eventually comes to a halt. When the rowing of the boat has stopped, the boat comes to a stop because of the frictional force exerted by water on it. The Frictional force is always in the direction opposite to the applied force.
Non-contact forces: Forces that arise without the contact of 2 or more objects involved. Examples: Magnetic Force, Electrostatic Force, Gravitational force.
Magnetic Force is a force that attracts certain metal objects (like iron and iron filings) towards a magnet.
