Existe una especie de pájaro en las islas Galápagos que puede ejercer una fuerza de 205N (Newton) con un pico para romper una semilla. Si su pico se desplazó 0,004m durante esta operación, ¿cuánto trabajo realiza el pájaro para conseguir la semilla? Ayuda por favor

In order to calculate the work that the spike did, you have to respect the following equation:

WORK = FORCE X DISPLACEMENT X COS (0)

Explanation:

Work is measured in joules, and is the amount of energy a body needs to make a certain force over a certain distance.

In the case of this bird we would be calculating with the equation written up in the previous item the work that said animal would do to grind a seed.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
