Which of these is one way that mechanical waves differ from electromagnetic waves?

question 4 options:

mechanical waves require energy and electromagnetic waves do not.

mechanical waves require a medium and electromagnetic waves do not.

electromagnetic waves require a medium and mechanical waves do not.

mechanical waves transmit matter and electromagnetic waves transmit energy.

Ineed the answer to question 1 , i’m desperate

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

If forces acting on an object are unbalanced. true or false
