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.

Answer:
it probs gos fast then it was it would be easy if u asked us if their was any mass or friton
Explanation:
Answer:
V = 6.36 m³
Explanation:
For this exercise we will use fluid mechanics relations, starting with the continuity equation.
Let's write the flow equation
Q = v₁ A₁
The area of a circle is
A = π r²
Radius is half the diameter
A = π/4 d²
Q = v₁ π/4 d₁²
Q = π/ 4 15 0.03 2
Q = 0.0106 m3 / s
The volume of water in t = 10 min = 10 60 = 600 s
Q = V / t
V = Q t
V = 0.0106 600
V = 6.36 m³
Answer:22.6g
Explanation:
Mass of water(mw)=1liter=1000g
Final temperature=20°C
Temperature of ice=0°C
Temperature of water=56°C
Change in temperature of water=56-20=36
change in temperature of ice=20-0=20
Specific heat of water=1cal/g°C
Latent heat of ice=79.7cal/g
1000x1x36=mx79.7x20
36000=1594xm
Divide both sides by 1594
36000 ➗ 1594=1594xm ➗ 1594
22.6=m of ice
m of ice=22.6g
Agree cause it is that persons environment not the law or the law makers
