The amplitude of a driven oscillator becomes maximum at a particular frequency known as

According to Galilean transformation equation what is invariant?

The operation by square of j vector operates on a vector rotates it through an angle

Rotation axis coupled with a translation parallel to the rotation axis will give rise to a symmetry  operation known as

Percolation is the process by which water moves downward through the soil, particularly through pores or spaces between soilparticles. 
This process allows water to spread quickly and evenly throughout the soil,ensuring that plants can access moisture and nutrients at various depths.

"Through which process does water spread quickly in soil?"

In an electric motor, the split ring commutator reverses the direction of current, allowing for continuous rotation of the motor in one direction
A split-ring commutator is essential in a d.c. motor because it reverses the direction of current in the coil every half turn. 
This ensures that the torque acting on the coil is always in the same direction, allowing continuous rotation.
