What does "a" mean in the equation f=ma

Acceleration

300

What is Newtons Third Law

For every action there is an equal and opposite reaction.

400

What is Newtons First Law

A object stays in motion until an unbalanced object is acted upon it and A object at rest stays at rest until a unbalanced object is acted upon it.

B Electromagnetic waves need a medium to travel through and mechanical waves can travel through a vacuum.

C There isn't a difference between the two.

D They both have wavelengths and frequencies and therefore are the same thing.Mechanical waves take place on Earth, but electromagnetic waves only take place in space.
