In subtraction, the result should be rounded to the least number of decimal places. 10.0 has one decimal place and 5.678 has three, so the answer should be rounded to one decimal place: 4.32 becomes 4.3.

When unpolarized light passes through a polarizer, its intensity is reduced to half of its original value.

Using the formula Vx/Vk = Lx/Lk, we have Vx = Vk * (Lx/Lk). Here, Lx = 4 m, Lk = 10 m, Vk = 12 V, thus Vx = 12 V * (4/10) = 4.8 V.

The condition for balance in a potentiometer is that the potential difference across the galvanometer must be zero, indicating that the unknown voltage is equal to the voltage across the potentiometer wire.

The circuit must be open when measuring the emf of a cell with a potentiometer to ensure that no current flows through the cell, allowing for an accurate measurement.

At balance, the potential difference across the cell equals the potential drop across the potentiometer wire.

Keeping the circuit closed ensures that the current flows properly, allowing for accurate voltage measurements.

A diode is a semiconductor device that utilizes the p-n junction principle to allow current to flow in one direction.
