Tenemos que calcular la energía necesaria para lle- nar un tanque. Recuerden que P = E/∆t. Necesitamos co-
nocer el tiempo que tarda una bomba en llenar el tanque.

Supongamos que, típicamente, una bomba de 3⁄4 de HP

(750 Watts), demora 30 minutos (0,5 hs) en llenar un tan-
que de 500 litros a 4 metros de altura. Por lo tanto E = P. ∆t

= 750W. 0,5 hs = 375 Wh

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.
