Does energy can be transmitted when wave pulses or disturbances are created? Why?

Yes, since the movement itself is an energy.

No, because wave pulse cannot transmit energy.

Maybe

It depends on how strong and slow it is.

How can we distinguish mechanical wave from electromagnetic waves?

Mechanical wave occur without the aid of a medium, while electromagnetic wave occur when waves travels through medium.

Mechanical waves occur when waves travel through a medium like solid, liquid, or gas, while electromagnetic waves occur without the aid of a medium.

Mechanical waves exist in sun’s ultraviolet rays while electromagnetic waves exist in radio waves.

Mechanical waves - wave movement would still exist without medium, while electromagnetic waves occur when only when there is medium like solid, liquid, or gas.
