(a) f = 5.00 × 10²⁰ Hz, E = 3.32 × 10⁻¹³ J;
(b) f = 1.20 × 10¹⁰ Hz, E = 7.96 × 10⁻²⁴J.

What's the similarity between a gamma ray and a microwave?
Both gamma rays and microwave rays are electromagnetic radiations. Both travel at the speed of light at 
in vacuum.
where
- f is the frequency of the electromagnetic radiation,
- c is the speed of light, and
is the wavelength of the radiation.
(a)
Convert all units to standard ones.
.
The unit of 
shall also be standard.
.
For each particle,
,
where
is the energy of the particle,
is the planck's constant where 
, and- is the frequency of the particle.
.
(b)
Try the steps in (a) for this beam of microwave with
.
Expect the following results:
, and
.
2 x 3 = 6 + 3 x 3 = 9. 6 +9= 15 + 5 = 20. 10 + 15 = 25.
So, The Al2 O 3 is 20.
And the Fe is 15?
So the total of whatever it is is 25.
Sorry if it's wrong, I am a 13year old 7th grader, not in high school so it's probably wrong.
Answer:
Explanation:
Hello!
In this case, considering the given chemical reaction:
Thus, by applying the law of rate proportions, we can write:
Whereas the stoichiometric coefficients of reactants are negative due their disappearance and that of the product is positive due to its appearance. In such a way, when we relate the rate of disappearance of hydrogen gas to the rate of formation of hydrogen iodide, we obtain:
Best regards!
Answer:
Freezing
Explanation:
When a liquid goes to a solid, this process is called freezing.
A foliated rock forms when the minerals are realigned due to the presence of high temperature and pressure. The minerals align in such a way that the axes are directed to where the pressure was applied.
