Answer: Approximately 15,192 kilometers
Answer:
Poynting vector,
Explanation:
It is given that, The electric and magnetic fields of an electromagnetic wave are given by :
Electric field,
Magnetic field,
We need to find the Poynting vector for this wave. the Poynting vector is given by :
So, the Poynting vector for this wave is . Hence, this is the required solution.
Matter is radioactive and decays over time
Henri Becquerel discovered that <span>uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
hope this helps</span>
The answer would be B. because the object is falling with constant velocity its acceleration is zero .
This is false. Atom in Greek means indivisible, or unable to be divided into smaller parts. We know now that it is not true, but they didn't.
