You are a high school track & field coach and you have a young female athlete who is running a competitive mile pace (5:20). This would make her competitive at the state and national level. You want to help this athlete to maintain and even increase her competitive potential. What would you do?
Answer:
By ensuring she is giving speed endurance training
Explanation:
Speed endurance training would be the most ideal in helping an athlete to maintain and even increase her competitive potential.
The speed endurance training would help the athlete maintain and attain a high speed for a longer duration of time.
This would make the athlete get used to running an improved time for much longer distances.

How many particles in 32.0 liters of helium
Number of particles : 8.603 x 10²³
Further explanationStandard conditions for temperature and pressure are used as a reference in certain calculations or conditions
Assumption⇒ Standard Conditions
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
1 mol = 6.02 x 10²³ particles (atoms, ions, or molecules)
32.0 liters of Helium
[tex]\tt mol=32:22.4=1.429[/tex]
Number of particles :
[tex]\tt 1.429\times 6.02\times 10^{23}\\\\=8.603\times 10^{23}[/tex]
Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R
Answer:
Unit of resistance is Ω (Omega).
Explanation:
The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :
V = IR
R is resistance
Its unit is Omega and it is represented by Ω.
The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer
What is resistance?Resistance is simply the measure of the opposition to current flow in an electrical circuit.
Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.
V = I × R
Where;
V is the voltage or potential difference. I is the current.R is the resistance.The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer

Describe how the particle motion is different from state to state.
Answer:
The particles in a gas are moving very quickly in random directions.
The particles in a solid are tightly packed and locked in place, and they are vibrating in their place.
The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other.

A student determines the density of an element to be 2.73 g/cm 3 . If the accepted value is 2.70 grams per cm 3 , what is the student's percent error? Identify the element. What is the boiling of this element in Celsius degree
Answer:
Explanation:
percentage error = error x 100 / correct value
= (2.73 - 2.70) x100 / 2.70
= 1.11 %
The element is Aluminium whose density is 2.702 grams / cc
Boiling point of Aluminium = 2519⁰C .

What is the relationship between the atomic mass of an element and a mole of that element's atoms?
Answer:
Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).
Explanation:
The relationship between the given terms is provided below throughout the below segment.
One mole of such a component's atomic weights is approximately equivalent to that component's atomic mass. This same atomic mass of the oxygen element, for example, is about 16g. As a result, one mole containing oxygen atoms equals 16g of oxygen ([tex]O_2[/tex]). 1 mole containing oxygen atoms weighs 16g.We can say that,
→ [tex]1 \ mole \ in \ gram \ of \ an \ element = Atomic \ mass \ of \ an \ element[/tex]

H2 + 02 --> H20
2H2 + O2 --> 2H20

2H₂ + O₂ ⇒ 2H₂O
Further explanationConservation of mass states that
In a closed system, the masses before and after the reaction are the same
So it can be concluded
mass of the reactants = mass of the productsmass cannot be created or destroyedThe number of atoms involved in a reaction remains the same⇒ number of moles also the samechemical equation in balanced formSo let's see which of the several options , which one has the same number of atoms on both sides of the equation
