Answer:
The speed of radio waves is approximately 185 miles per second, which is also the speed of light.
Explanation:
The reason that radio waves travel at the speed of light is that they are a type of electromagnetic radiation.
Explanation:
Fgravity = G*(mass1*mass2)/D²
so, if you double one of the masses, what does that do to our equation ?
Fgravitynew = G*(2*mass1*mass2)/D²
due to the commutative property of multiplication
Fgravitynew = 2* G*(mass1*mass2)/D² = 2* Fgravity
so, the correct answer will be 2×45 = 90 units.
A). Scale.
You CAN measure volume with all the following except a scale.
