What is meant by polarization? Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. In linear polarization, the fields oscillate in a single direction. Are mirrored lenses […]

What is the minimum resultant?
What is the minimum resultant? The resultant of a number of forces acting on a body is the vector sum of all the forces acting on the body. The maximum resultant forces is found when all the forces have the same direction (parallel forces). The minimum resultant force is found when forces act in exactly […]
What is an example of dissolve?
What is an example of dissolve? Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. The sodium chloride (salt) dissociates into sodium and chloride ions when it is mixed with water. Releasing the helium from a balloon into the atmosphere is also an example […]
Why do they sweep in curling?
Why do they sweep in curling? Curlers sweep the ice to help the stone travel farther and straighter. This film reduces the friction between the stone and ice. The curling team is strategic in how much sweeping they do in front of each stone. If they want a stone to travel farther with less curl, […]
What is symbol for current?
What is symbol for current? Symbol. The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity).
