The SI unit of time is the second, which is defined as 9,192,631,770 cycles of radiation associated with a certain emission process in the cesium atom. Calculate the wavelength of this radiation (to three significant figures).

Answers

Given:

Radiation emission in Cs atom = 9,192,632,770 cycles

To determine:

The wavelength of the above radiation

Explanation:

It is given that :-

1 sec equivalent to 9,192, 631, 770

Now, frequency (ν) = cycles /sec = 9,192, 631, 770/sec

Wavelength of a radiation is given as:

λ = c/ν

where c = speed of light = 3*10⁸ m/s

λ = 3*10⁸ ms⁻¹/9,192, 631, 770 s⁻¹ = 0.0326 m

Ans: Thus the wavelength of this radiation is 0.033 m
To calculate the wavelength of this radiation if the SI unit of time is the second, which is defined as 9,192,631,770 cycles of radiation associated with a certain emission process in the cesium atom, the wavelength is one cycle of radiation, and therefore the wavelength is 1/9192631770

hich of the following statements is true about cocaine? multiple choice cocaine is a powerful central nervous system opiate. cocaine may cause users to become overweight. cocaine hydrochloride powder produces a higher rate of dependence than crack cocaine.

Answers

Injecting or smoking cocaine produces a quicker strong high than snorting it.


Cocaine is a powerfully addictive stimulant drug crafted from the leaves of the coca plant local to South the us. despite the fact that healthcare companies can use it for legitimate medical functions, including neighborhood anesthesia for a few surgical procedures, leisure cocaine use is unlawful. As a street drug, cocaine looks as if a best, white, crystal powder. road sellers regularly blend it with things like cornstarch, talcum powder, or flour to growth earnings. they will also blend it with other tablets including the stimulant amphetamine, or synthetic opioids, along with fentanyl. adding synthetic opioids to cocaine is specifically risky whilst humans using cocaine don’t recognize it carries this dangerous additive. increasing numbers of overdose deaths among cocaine users might be related to this tampered cocaine.

After 56.0 min, 40.0% of a compound has decomposed. What is the half‑life of this reaction assuming first‑order kinetics?

Answers

Answer:

Go ahead and plug in the percentages and time to find the answer.

Explanation:

The amount of a substance with half-life h, that remains after time t is 0.5t/h

 

Since 26% has decomposed, 74% remains.

 

So .74 = 0.580/h

 

ln .74 = (80/h) ln 0.5

 

h/80 = ln 0.5 / ln .74

 

h = 80 ln 0.5 / ln .74

 

h = 184.16 minutes
