Answer:

The electron moved down to an energy level and has an energy of

10.92 \times 10^{-19} \textsf{J}

Step-by-step explanation:

\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}

\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

\triangle E=E_2-E_1

\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1

\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}

\implies E_1= 10.92 \times 10^{-19}

<u>Answer</u>:

The electron moved down to an energy level and has an energy of

10.92 \times 10^{-19} \textsf{J}

HELP ME OUT PLS!!!!!​
miskamm [114]

Answer:

x = 26

Step-by-step explanation:

Supplementary angles mean that when the two angles are added together, they add up to 180. With this info, we can set the two expressions equal to 180

124 + (2x + 4) = 180.    

128 + 2x = 180    combine like terms

2x = 52      subtract both sides by 128

x = 26.      divide both sides by 2

A new car battery is sold with a two-year warranty whereby the owner gets the battery replaced free of cost if it breaks down du
Mariana [72]

Answer:

4.01% probability that the battery will break down during the warranty period

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 45, \sigma = 12

a. What is the probability that the battery will break down during the warranty period

Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.

Z = \frac{X - \mu}{\sigma}

Z = \frac{24 - 45}{12}

Z = -1.75

Z = -1.75 has a pvalue of 0.0401

4.01% probability that the battery will break down during the warranty period
