Based on the information given, it should be noted that sound travels through air, and putting your ear to a wall will not allow the person to hear the noise on the other side better. Therefore, it is false.

It should be noted that when sound is created, the air particles vibrate and collide with each other. The vibrating particles pass the sound through to a person's ear and then vibrate in the eardrum.

Sound travels through air, and putting your ear to a wall will not allow the person to hear the noise on the other side better. In such a case, the noise will be better heard when it travels through the air.

In conclusion, sound needs a medium such as air to travel.

Explanation:

The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails

The percent error in the initial measurement would be 6.47%

Percent error in any measurement is mathematically given as:

                    absolute error/true measurement x 100%

In this case;

True measurement = 1.34 qt

Absolute Error = 1.34 - 1.25

                         = 0.09 qt

Percent error = 0.09/1.34 x 100%

                      = 6.47%

Answer: An arbitrary rigid rotor is a 3-dimensional rigid object, such as a top

Explanation: The rigid rotor is a mechanical model of rotating systems. ... A special rigid rotor is a linear rotor requiring only two angles to describe, for example, a diatomic molecule. More general molecules are 3-dimensional, such as water (asymmetric rotor), ammonia (symmetric rotor), or methane (spherical rotor).

Answer:

1. a = 2, b = 1 and c = 2

2. a = 1, b = 3, c = 2 and d = 2

Explanation:

According to law of conservation of mass, the mass can neither be created nor destroyed.

Hence, for a chemical equation the left hand side should be equal to the right hand side.

Therefore, the two balanced equations are;

2 CO + O₂ → 2 CO₂

C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O

Answer:

1.1328 g left after 15.6 years

Explanation:

First we need to find, that how many times it decays: 15.6 ÷ 2.60 = 6 times

Then we know the formula: mass of original ÷ 2^n = remaining mass.

                                           :     72.5   ÷   2^6 = 1.1328 g left.

Answer:

remaining mass = 1.13 grams (3-sig figs)

Explanation:

All radioactive decay follows 1st order kinetics and is defined by the expression ...

A = A₀e^⁻kt

A = final mass activity

A₀ = initial mass activity

k = rate constant = 0.693/t(half-life) = 0.693/2.60 yrs = 0.2665 yrs⁻¹

t = time of decay = 15.6 yrs

A = (72.5 g)(e^[-(0.2665 yrs⁻¹)(15.6yrs)] = 72.5 grams x 0.0156

= 1.13381331 grams (calc. ans.) ≅ 1.13 grams (3 sig figs)

Hello!

Complete ionic equations separate the equations into ion forms. Weak electrolytes and solids (precipitate) are exempt from this rule.

Net ionic equations are complete ionic equations but the ions that don't form as a precipitate are left out of the equation.

Anything cancelled out from the complete ionic equations are considered the spectator ions.

Looking at the equation, there are no weak electrolytes (you might have not covered this material yet), and the only precipitate in the solution is [tex]V(OH)_3[/tex].

1. What is the complete ionic equation?

Let's ionize the equation. Make sure all the atoms are correspondent with their coefficients. Don't forget their charges.

[tex]3Li^+(aq)+3OH^-(aq)+V^3^+(aq)+3Cl^-(aq)= 3Li^+(aq)+3Cl^-(aq)+V(OH)_3(s)[/tex]

Label every ion as (aq), and check the periodic table for their charges. Even without looking for V, we know that it is a 3+ charge since there are 3 chlorines attached to it.

2. What is the net ionic equation?

Get rid of all of the ions that don't do anything. Consider them lazy if they don't precipitate or form a solid. In this case, anything other than V and OH should be removed since they don't react. Think of it as cancelling out the ions that are still ions both sides.

[tex]V^3^+(aq)+3OH^-(aq)=V(OH)_3(s)[/tex]

3. What are the spectator ions?

Spectator ions are the cancelled out ions from the previous problem.

[tex]3Li^+(aq)~, 3Cl^-(aq)[/tex]

Answer:

Explanation:

if you walk one mile North and then turn and walk another two miles you walk 3 miles and then turn around and walk back in the same direction you would end backup at the one-mile Mark he began. So three miles there two miles back

Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.

Cassidee's motion forms a right triangle. Her first leg is 1 mile north, and her second leg is 2 miles west. Using the Pythagorean theorem:

Distance = √(1 mile)² + (2 miles)²

Distance = √1 + 4 = √5 ≈ 2.24 miles.

For displacement, we consider her initial and final positions. The horizontal component (westward) is 2 miles, and the vertical component (northward) is 1 mile. Using the Pythagorean theorem:

Displacement = √(Horizontal)² + (Vertical)²

Displacement = √2² + 1²

Displacement ≈ √4 + 1 = √5 ≈ 2.24 miles.

However, displacement needs a direction. Since she moves west, displacement is -2 miles west.

In summary, Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.
