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.
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.
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.
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.

Which action by one of the students is most disruptive to the discussion? One listener interrupts the speaker by inserting an opinion. One student laughs at the opinion presented by another student. One listener maintains eye contact with the speaker. The teacher calls on the next student to express a viewpoint.
Answer:A
Explanation:One listener interrupts the speaker by inserting an opinion.
One of the main things that prevents people from listening is noise, which is anything that makes it difficult to pay attention to and comprehend what is being spoken. Thus, option A is correct.
What are the interrupts affecting the listener by opinion?The act of interjecting communicates to the speaker your disinterest in what they have to say. You don't have time to actually listen to them or believe your voice is more essential.
It might even give the impression that you weren't paying attention at all and were simply waiting for an opportunity to speak.
Frequent interruptions can also double error rates, increase rates of tiredness, and stress-related illnesses. The next time you are tempted to interrupt a coworker who is hard at work with a brief comment, consider the effect you will have.

according to hund's rule, the lowest (ground) state of the silicon atom.....
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.
The starting point :The lowest energy state for an electron is called its ground state, which is the energy level it typically resides in.
