What is the wavelength of light with 2.89 x 10-19 J of energy? (The speed of

Alika [10]

Let's see

$\\ \rm\rightarrowtail E=hv$

$\\ \rm\rightarrowtail E=\dfrac{hc}{\lambda}$

lambda is wavelength
h is Planck constant
c is velocity of sound in air
E in energy

$\\ \rm\rightarrowtail \lambda=\dfrac{hc}{E}$

$\\ \rm\rightarrowtail \lambda=\dfrac{6.626\times 10^{-34}\times 3\times 10^8}{2.89\times 10^{-19}}$

$\\ \rm\rightarrowtail \lambda=6.878\times 10^{-7}m$

$\\ \rm\rightarrowtail \lambda=68.8\mu m$

What is maximum mass of carbohydrate in a 6-oz serving of diet soda that contains less than 1 Calorie per can if the average num

masya89 [10]

Answer:

0.24 g

Explanation:

Given that:

The average number of the calories for the carbohydrates = 4.1 calorie / g

Also,

6 - oz serving of the diet soda contains less than 1 calorie per can

So,

Maximum mass of carbohydrate = Maximum calorie / Average number of the calories for the carbohydrates

The maximum of the calorie can be 1 calorie per can

So,

<u>Maximum mass of carbohydrate = 1 calorie / 4.1 calorie / g = 0.24 g</u>
