Which describes how electromagnetic waves travel

a. they can only travel through a medium.

b. they can travel through a vacuum but not through matter.

c. they can travel through matter and through a vacuum.

d. they can only travel through matter.

c. They can travel through matter and through a vacuum.

Explanation: Electromagnetic waves are waves which do not require medium to travel. Example: Light

Mechanical waves are waves which require material medium to travel through them.  Mechanical waves require the presence of a material medium in order to transport their energy from one location to another. Example: Sound

Mechanical waves  can only travel through a medium and they can only travel through matter.

not moving. pos accel,

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
