It should be noted that the angular momentum remain constant  and kinetic energy of the skater increases.

<h3>What is Angular momentum?</h3>

Angular momentum  can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then  angular momentum is constant.

Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.

Which of the following species has the same number of protons as fe³⁺?
mafiozo [28]

The number of protons in an element is the atomic number of the element, and it is not affected by the charge on the element. Hence, the species which has similar Number of proton is Fe²⁺

To know the species which the same number of protons as Fe³⁺, we need to obtain the <em>atomic number of the elements on the periodic table</em> :

  • Fe³⁺, Atomic number = 26; Number of protons = 26

  • Mn³⁺, Atomic number = 25; Number of protons = 25

  • Co²⁺, Atomic number = 27; Number of protons = 27

  • Fe²⁺, Atomic number = 26; Number of protons = 26

  • Ni, Atomic number = 28; Number of protons = 28

Therefore, only Fe²⁺ has the same number of protons as Fe³⁺

explain why the percentage of people with $300,000 or more increases so substantially across the age groups.
MrRa [10]

The percentage of people with $300,000 or more increases so substantially across the age groups because older individuals have an edge when it comes to accumulating wealth.

<h3>What are the age groups?</h3>

Simply put, older folks have more money because:

1. They have worked for longer periods of time and are thus anticipated to earn higher incomes and hold higher positions.

2. They have had more time to save and invest their money.

Every age group has a greater ability to save money during their working years. Young individuals just starting out in their jobs are less likely to amass enough money to be worth that much.

More about the age group link is given below.
