Electric Dipole

The given circuit consists of three logic gates:

• NOT gate: The output of the NOT gate is the negation of the input.
• AND gate: The output is 1 only when both inputs are 1, otherwise 0.
• OR gate: The output is 1 if at least one input is 1.

The first gate is a NOT gate. It takes input , so the output of the NOT gate, , will be:

The second gate is an AND gate, which takes inputs and . The output of the AND gate, , will be:

The third gate is an OR gate, which takes inputs and . The output of the OR gate, , will be:

Thus, the values of and are:

Thus, the correct answer is Option (1), .

The maximum power output from the river can be calculated using the formula for the kinetic energy of flowing water. The power is given by:

where:

• is the density of water,
• is the cross-sectional area of the river,
• is the velocity of water.

The cross-sectional area of the river is:

Now, substituting the values into the power formula:

Thus, the maximum power output from the river is 2 MW.
