The answer is substance A
That's false. Displacement would be (r2 - r1) .
What is actually happening is that energy is being used then "recycled" in a sense.
Answer:
Explanation:
Speed of light is the product of its wavelength and frequency, expressed as
S=fw
Where s represent speed, f is frequency while w is wavelength
Making f the subject of the formula then
f=s/w
Substituting 2.99x10^8 m/s for s and 3.012x10^-12 m for w then
Therefore, the frequency equals to
Anything that is made up of atoms.
