if you slide down a rope, it's possible to create enough thermal energy to burn your hands or your legs where they grip the rope. suppose a 40kg child slides down a rope at a playground, descending 2.0m at a constant speed. how much thermal energy is created as she slides down the rope? assume that all potential energy can be transformed into thermal energy.

Answers

Answer 1

Answer:

Given,

mass, m=40kg

length of rope, h=2m

Required,

Thermal energy.

Assumption;

The P.E can be transformed to thermal energy.

then,

P. E = Thermal energy.

Since,

P.E = mhg

Thermal energy = mhg

T.E = 40*2*9.8

T. E = 784J

Therefore the thermal energy created will be 784J.

The best summary of the theme that is developed in this section of the play is those who pursue revenge are often destroyed by it.

What is theme?

Theme is defined as a central message or underlying meaning that an author conveys in a literary work and that the reader interprets. A literary topic is the central idea or underlying meaning that a writer focuses on in a novel, short tale, or other literary work. Characters, setting, dialogue, storyline, or a combination of these aspects can all be used to convey a story's theme.

People ought to just stay away from revenge since it never ends well. No matter what, fighting is never a good way to address a problem. Fighting is foolish, and it would be preferable to discuss instead. Retaliation frequently results in destruction for its victims.

3.00 l of a gas is collected at 35.0°c and 705.0 mmhg. what is the volume at stp?

Answers

Answer:

2.47L

Explanation:

Using the combined gas law equation as follows:

P1V1/T1= P2V2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

P1 = 705mmHg

P2 = 760mmHg (STP)

V1 = 3.00L

V2 = ?

T1 = 35°C = 35 + 273 = 308K

T2 = 273K (STP)

Using P1V1/T1= P2V2/T2

705 × 3/308 = 760 × V2/273

2115/308 = 760V2/273

Cross multiply

308 × 760V2 = 2115 × 273

234,080V2 = 577,395

V2 = 577,395 ÷ 234,080

V2 = 2.47L

Hydrogen selenide (H2Se) reacts with water according to the following equation. H2Se H2O → SeH– H3O In three to five sentences, identify the acid, base, conjugate acid, and conjugate base in this reaction. Use patterns in the periodic table to explain why the substances you identified acted as the acid and the base in this reaction.

Answers

Taking into account the Brønsted-Lowry acid-base theory:

H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.

In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

In this case, you know:

H₂Se + H₂O → SeH⁻ + H₃O⁺

H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.

So, H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.

Answers

Answer:

do me parese en ingles tu preguntaano entien

Explanation:

      According to Hund's rule, all electrons in singly occupied orbitals in subshells have the same spin before any particular orbital becomes doubly occupied.

Does Hund's law explain the electron configuration with the lowest energy?

       According to the Hunds Rule of Maximum Multiplicity, the term with the greatest number of electrons falls into the lowest energy range for a certain electron configuration. This rule states that p, d, and f orbital electron pairing cannot take place until each orbital of a specific subshell has one electron in it or is solely occupied.

      Think about the substance silicon (atomic symbol Si). 14 electrons, 14 protons, and (in most cases) 14 neutrons make up silicon. According to the energy diagram on the left, silicon contains two electrons in the n = 1 energy level, eight in the n = 2 energy level, and four in the n = 3 energy level in its ground state.

     Silicon's electrical structure is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 2 in its ground state.
