Why can television satellites, which broadcast information as electromagnetic radiation, send signals from the vacuum of space?
a) because electromagnetic radiation increases as the distance increases
b) because electromagnetic radiation does not need a medium to travel through
c) because space does not provide a medium that will block the satellite signals
d) because space is so vast that light waves can spread out to their full size and strength

The correct answer is Option B.

Explanation:

Electromagnetic waves are defined as the waves which have electrical and magnetic component associated with them. These waves are known as  transverse waves.

In these waves, particles of the medium travel perpendicular to the direction of the wave. These waves does not require any medium to travel through. They can travel through the vacuum.

Hence, the correct answer is Option B.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
