The outer sections are called emitter and collector.

Explanation

Remember that water has 2 lone pairs on oxygen.

Hence, according to VSEPR theory, the water molecule arrives at a bent or a V-shape

Due to the presence of lone pair-lone pair, lone pair-bond pair and bond pair-bond pair repulsions

Explanation

The molality (m) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0mol of NaCl dissolved into 1.0kg of water is a "one-molal" solution of sodium chloride.

The symbol for molality is a lower-case m written in italics.

Light glare can be reduced by the process of polarization.

Polarization is a process that involves filtering out light waves that are oscillating in certain directions.

Glare occurs when light waves from a source, such as the sun or a bright artificial light, are scattered in various directions, leading to a harsh and uncomfortable brightness.

The induced current can be positive or negative depending on the direction of the change in magnetic flux and the orientation of the coil

However, the term "induced current" is used to refer to the current that flows

As a result of electromagnetic induction, regardless of its direction being positive or negative
