Answer:
36watts
Explanation:
Data obtained from the question include:
R (Resistor) = 4 Ohms
V (Voltage) = 12V
P (power) =?
P = IV
Recall: I = V/R
P = V^2 /R
P = (12)^2 /4
P = 144/4
P = 36watts
Therefore, power is 36watts
Under water turbans that are placed at the above to middle of the ocean they are used to capture kinetic motion
Duracell batteries are an example of an electrochemical cell that is powered between the reaction of Magnesium and Zinc, occurring in basic conditions (alkaline battery). This type of reaction has a precise output of 1.5 volts, and looks like this:
Zn + 2MnO2 ➡️ ZnO + Mn2O3
It’s not rechargeable.
Golf Cart Batteries are an example of an electrochemical cell that is powered by the reaction between Lead and Sulfuric Acid (Lead-Acid battery). This type of reaction occurs on larger scales than an alkaline battery, and thus can generate a variety of powers depending on how many instruments are present within the battery. The reaction looks like this:
PbO2 + Pb + 2H2SO4 ➡️ 2PbSO4 + H2O
This is a rechargeable cell, but is rather prone to discharging by the environment and surroundings of the battery.
I do believe that the answer is D.
Hope this is right! Have a great day! :-)
