There are many kinds of natural disaster. One of which
is flood. Flood is a condition that the water level increases because of the
stuffing off of the water current in the river or moat. Rain usually
occurs because of heavy rains and human activities.
Flood happen because human activities, such as illegal
logging, littering, and so on. For example people throw garbage in the river,
so the river became clogged, and if heavy rains come, the river will overflow
and cause flooding
Flood has many effects like death, financial loss,
disease, damage to
public facilities and infrastructure, and many
more. We can prevent flood by cleaning the environment by doing reforestation,
dispose of waste in place, clean gutters and clogged rivers, etc.
How The fuel lamp working
Many cars, motorcycles
and other modern vehicles have fuel warning light devices. the warning light is
usually red which switches on automatically when the level of fuel in the tank
is very low. The warning light gives the driver information about the amount of
petrol in the tank. When the light switches on red, it tells the driver that
the petrol in the tank is almost empty. Therefore he have to put more fuel into
the tank. However do you know how the fuel warning works?
Well this is the way the fuel warning light work and gives the driver information about the accurate amount of the petrol in the tank. When the level of the fuel falls, the float inside the tank moves downwards. When this condition happens, the arm also moves downwards and it make the lever touch an electrical contact. This switches on the fuel light in the car dashboard.
The red light which appears in the fuel panel of the dashboard tells the driver that he needs more petrol for his car. When he pours more petrol into the tank, this condition makes the fuel level rise and it pushes the float upwards. In return it disconnects to the electrical contact and makes the red light switch off.
