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

URGENTEE:(​

Iam not sure but to me it with be a or dsorry if i was late! hope this ! : )if you really want me to find out the answer that is correct tell me and i will do more research but the a or d makes sense to me.

The casefor proofs

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
