a system absorbs 52 joules of heat and does work using 25 joules of energy. what is the change in the internal energy of the system? 25 joules 27 joules 52 joules 77 joules

Answers

Answer 1

The change in the internal energy of the system is 27 joules

From the question given above, the following data were obtained:

Heat absorbed (Q) = 52 JWork (W) = –25 J (since work is done by the system) Change in internal energy (ΔU) =?

The change in the internal energy of the system can be obtained as follow:

ΔU = Q + W

ΔU = 52 + (–25)

ΔU = 52 – 25

ΔU = 27 J

Therefore, the change in the internal energy of the system is 27 J

If you have a choice to earn simple interest on $10,000 for three years at 8% or annually compounded interest at 7. 5% for three years which one will pay more and by how much?.

Answers

Answer:

annually compounded interest at 7. 5% for three years will pay more by $22.97

Explanation:

Simple interest

A = P (1+ rt)

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

A = 10000(1+0.08x3) = $12,400

Annual compound interest

A = P (1+ r/n)^nt

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

A = 10000(1+0.075/1)^(1x3) = $12,422.97

$12,422.97 - $12,400 = $22.97

what is the effective nuclear charge for a 2nd row electron in sulfur?

Answers

Sulfur valence electrons have an effective nuclear charge of +6.

What are effective nuclear charge?

Effective nuclear charge is defined as the true positive nuclear charge that an electron in a multi-electron atom experiences. Electrons and protons are the two elements that cause the effective nuclear charge to rise. Zeff = Z - S is the actual nuclear charge.

A sulfur second row electron's effective nuclear charge is 14. Since sulfur contains 16 protons, or 16 atomic numbers, we know that there are 2 electrons in its first shell or orbit, which due to its rapid speed creates a shielding effect.

Thus, sulfur valence electrons have an effective nuclear charge of +6.

The valence electrons in an atom of phosphorus in the ground state are all found in.

Answers

Answer:

Valence electrons in an atom of phosphorus in the ground state are found in 3rd shell.

Explanation:

Phosphorus has an atomic number of 15. Its electronic configuration is 2, 8, 5. This configuration implies that, phosphorus electrons are distributed in three different shells and the number of electrons in the outermost shell, which is the third shell, is 5. The ground state refers to a state, where the atoms of phosphorus are not excited. Electrons move away from their ground states when they are excited.

The couple needs down payment of 20% of the purchase price for any home. Let d represent the most expensive home they can afford. If the couple has saved $35,000:

20% of d = 35000

0.2d = 35000

d = $175000

If you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at.

Answers

TIMESTAMPS

A timestamp is an indication (also called a marker) which tells us at what time / when the relevant text was spoken. They are represented in the format [HH:MM:SS]; where HH are hours, MM are minutes, and SS are seconds - from the beginning of the audio or video file.

There are different kinds of timestamps as below:

1. Periodic timestamps - Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.

2. Paragraph timestamps

3. Sentence timestamps

4. Speaker timestamps

Time stamping format used while transcribing audio files is:

[00:00:00]    

where [hour:minute:second]

so 5th minute is [00:05:00]

If the 5 - 15 minute part of an audio has to be transcribed stamping should be started at [00:05:00]

If a client requests time stamping every 30 seconds the next timestamp would be [00:05:30]

Similar Shapes

In order to get the height of the smaller rectangle, we will use the similarity theorem of shapes.

For the given rectangles:

Let B and b be the base of the larger and smaller rectangle respectivelyLet H and h be the height of the larger and smaller rectangle respectively

According to the theorem:

[tex]\frac{B}{H} = \frac{b}{h}[/tex]

Substitute the given parameters into the formula:

[tex]\frac{8}{3} =\frac{5}{h}\\8h = 3 \times 5\\8h = 15\\h =\frac{15}{8}\\h= 1.875in[/tex]

From the question, we have the following highlights

The quadrilaterals are similar (not congruent)Quadrilateral 2 is twice the size of quadrilateral 1

The above highlight (1) means that, quadrilateral 1 can be translated to get 2.

After the translation, the new quadrilateral 1 can then be dilated by 1/2 (this is so because quadrilateral 2 is twice the size of quadrilateral 1.
