Radio waves in a vacuum travel at the speed of light because they are a type of electromagnetic radiation like a light has been measured as traveling at 3×10^8 m/s in a vacuum.
Charged particles that are accelerating, like time-varying electric currents, are what produce radio waves. Radio and television signals are transmitted using radio waves, and microwaves used in radar and microwave ovens are also radio waves. Radio waves are emitted by a lot of celestial bodies, including pulsars. High RF exposure levels have the potential to heat biological tissue and raise body temperature. The body's inability to handle or remove the extra heat that could be generated by high RF exposure in humans could result in tissue damage.

Critical Thinking means to rush to find a solution for a problem - Inference means to having a conclusion to the situation you were facing.
What they both have in common is that if you are facing a problem, you have to come up with a good solution so that you would have a conclusion to the problem you had in the first place.
it occurs when the energy of the combination has lower energy than the separated atoms
Answer:
direction, speed
means the object is staying still, 0
newtons, N
the sum of all the forces acting on an object
Explanation:
Answer:
Its density decreases, and its volume increases
Explanation:
Density is defined as Mass/Volume. What happens when water transforms into ice is that its density decreases because the volume the molecules now occupy increases.
The denominator of the rational expression 
is now larger (while the numerator stays the same), so the quotient gives a smaller number.
