What is the energy of an electromagnetic wave with a electromagnetic wave with a frequency of 3 * 10 Hz ?
Olin [163]

Answer:

E=1.989*10^{-32}J

Explanation:

From the question we are told that:

Frequency f=3 * 10 Hz

Generally the equation for Energy of an electromagnetic wave is mathematically given by

 E=hf

Where

  h=Planck's constant

  h=6.62607015 * 10^{-34}

Therefore

 E=6.62607015 * 10^{-34}*3 * 10

 E=1.989*10^{-32}J

A molecule of antifreeze, ethylene glycol, has the formula c2h4(oh)2. how many atoms are there in one molecule of antifreeze?
kifflom [539]
Answer is: there are ten atoms in one molecule of antifreeze.
One molecule of ethylene glycol (C₂H₄(OH)₂) has two carbon atoms, six hydrogen atoms (4 + 2 · 1) and two oxygen atoms (2 · 1). So there are:
2 + 6 + 2 = 10 atoms.
Ethylene glycol (C₂H₄(OH)₂) is an odorless, sweet-tasting, colorless viscous liquid.
