We should be worried about deforestation as it would lead to floods, increase in earth’s temperature, decreasing animals habitats and soil erosion. Damage to forests directly or indirectly affects human habitat and environment so it must be a matter of concern among us.

A sport person and athletes drink more water to fluid loss from the body. Fluid loss mainly happens four different ways, of which only some may apply to you and your athletes:
Exercise Intensity: Exercising for hours (like in endurance sports) means a greater need for fluids and an increased need to create a hydration plan to avoid becoming dehydrated.
Sweating: Some athletes sweat more than others, and those that sweat a large amount are at a greater risk of severe dehydration.
Temperature: Exercising in hot weather increases the amount of fluid lost through sweating. Conversely, exercising in the cold can impair the ability to recognize dehydration and also increases the amount of fluid lost through breathing.
Altitude: Exercising at higher altitude has a dehydrating effect on the body and increases the amount of fluid needed to feel sufficiently hydrated.

Electric Bell: It consists of a coil of wire wound on an iron piece. The coil acts as an electromagnet. An iron strip with a hammer at one end is kept close to the electromagnet. There is a contact screw near the iron strip. When the iron strip is in contact with the screw, the current flows through the coil which becomes an electromagnet. It, then, pulls the iron strip. In the process, the hammer at the end of the strip strikes the gong of the bell to produce a sound. However, when the electromagnet pulls the iron strip, it also breaks the circuit. The current through the coil stops flowing. The coil is no longer an electromagnet. It does not attract the iron strip. The iron strip comes back to its original position and touches the contact screw again. This completes the circuit. The current flows in the coil and the hammer strikes the gong again. The clapper strikes the gong rapidly producing almost continuous sound. This is how the bell rings.

An electric bell consists of an iron core, on which is wound a wire as a coil. One end of the coil is connected to one terminal of a battery, and the other end to a steel rod that acts like a spring for the hammer touching the screw contact. The other terminal of the battery is connected to the screw contact with a switch in the middle.
