Answer:
Explanation:
energy for photon is calculated in same wasy as for electromagnetic radiation
energy for electromagnetic radiation = hf
where f is the frequency of photon
h is Planck's constant = h = 4.14 × 10−15 eV · s.
thus
energy of photon = 4.14 × 10−15 eV · s * 2.36 x 10-19 Hz
energy of photon = 9.77 * 10−(-15+ -19) eV
energy of photon = 9.77 * 10−34eV answer
Answer:
4. Atmospheric pressure decreases as altitude increases.
Explanation:
hope this helps and is right. p.s i really need brainliest :)
Answer:
Explanation:
Endothermic reactions absorb energy from the surrounding, but exothermic reactions release energy to the surrounding.
