What does a mechanical wave do with its energy?

Answers

Answer 1

Answer: A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission the material is limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy.

What percent of the gross domestic product (GDP) is currently generated by the service industry?


68 percent

71 percent

82 percent

95 percent

Answers

The answer is 71 percent. To be more exact, it is 70.38.

The global economy is heavily reliant on the service sector, which accounts for more than two-thirds of global GDP, over three-quarters of foreign direct investment in advanced nations, the majority of worker employment, and the majority of job growth. Thus, option B is correct.

What GDP is generated by the service industry?

The service sector, often known as the tertiary sector, makes up the third tier of the three-sector economy. Instead of creating products, this sector provides training, consulting, and maintenance and repairs.

The GDP of the nation is significantly impacted by the service sector. Through trade in services, it not only generates many jobs, but also significantly improves the country's economic performance.

Therefore, 70% of GDP is made up of consumer expenditure. The retail and service sectors are important to the American economy.

When looking at the effect of PH on sucrase activity, what was the wavelength of light used in the spectrophotometer?

Answers

Answer:

540 nm

Explanation:

Sucrase is a digestive enzyme. It is the catalyst in the hydrolysis of sucrose into the two subunits that it is made up of namely; fructose and glucose.

Enzymes are known to function best at optimum pH. As the pH of sucrase departs from its ideal pH, its activity decreases.

The activity of sucrose is studied using a spectrophotometer of wavelength about 540nm.

In the diagram, q1 = -6.39*10^-9 C and q2 = +3.22*10^-9 C. What is the electric field at point P? pls help

Answers

Answer:

Below

Explanation:

First draw the vectors that represent both electric fields.

E1 is the elictric field created by q1, E2 is the one created by q2.

● q1 is negative so E1 will point from P.

● q2 is positive so E2 will point out of P

(Picture below)

■■■■■■■■■■■■■■■■■■■■■■■■■■

The resulting electric field is equal to the sum of the two fields since both vectors are colinear.

Let E be the total field.

● E = E1 + E2

The formula of the electric field intensity is:

● E = K ×(q/d^2)

-K is Coulomb's constant

-d is the distance between the charge and the object ( here P)

-q is the charge

■■■■■■■■■■■■■■■■■■■■■■■■■■

● E1 = K × (q1/d1^2)

The distance between q1 and P is the qum of 0.15 m 0.25 m. (0.4 m)

Coulombs constant is 9×10^9 m^2/C^2

● E1 = 9×10^9 ×[-6.39 × 10^(-9)/ 0.4^2]

● E1 = -359.43 N/C

■■■■■■■■■■■■■■■■■■■■■■■■■■

● E2 = K ×(q2/d^2)

The distance between q2 and P is 0.25 m.

● E2 = 9×10^9×[3.22×10^(-9) /0.25^2]

● E2 = 463.68 N/C

■■■■■■■■■■■■■■■■■■■■■■■■■■

● E = E1 + E2

● E = -359.43+463.68

● E = 105.25 N/C

In the diagram, q1= +8.0 C, q2= +3.5 C, and q3 = -2.5 C. q1 to q2 is 0.10 m, q2 to q3 is 0.15 m. What is the net force on q2? Label sign for charges (+ or -). (Unit = N). pls help?

Answers

Answer:

f(t) =  28,7 [N]

Explanation: IMPORTANT NOTE: IN PROBLEM STATEMENT CHARGES ARE IN C (COULOMBS) AND IN THE DIAGRAM IN μC. WE ASSUME CHARGES ARE IN μC.

The net force on +q₂  is the sum of the force of +q₁  on +q₂ ( is a repulsion force since charges of equal sign repel each other ) and the force of -q₃ on +q₂ ( is an attraction force, opposite sign charges attract each other)

The two forces have the same direction to the right of charge q₂, we have to add them

Then

f(t) = f₁₂ + f₃₂

f₁₂ = K * ( q₁*q₂ ) / (0,1)²

q₁  = + 8 μC     then   q₁ = 8*10⁻⁶ C

q₂ =  + 3,5 μC  then  q₂ = 3,5 *10⁻⁶ C

K = 9*10⁹  [ N*m² /C²]

f₁₂ = 9*10⁹ * 8*3,5*10⁻¹²/ 1*10⁻²   [ N*m² /C²]* C*C/m²

f₁₂ = 252*10⁻¹ [N]

f₁₂ = 25,2 [N]

f₃₂ =  9*10⁹*3,5*10⁻⁶*2,5*10⁻⁶ /(0,15)²

f₃₂ =  78,75*10⁻³/ 2,25*10⁻²

f₃₂ =  35 *10⁻¹

f₃₂ =  3,5 [N]

f(t) =  28,7 [N]

Both acids and bases produce ions when dissolved in water. Propose a way to describe what

hydroxide ions (OH-) and H+ (hydrogen) ions are. What do they have to do with acids and

bases and the pH scale?

Answers

Answer:

See explanation

Explanation:

Acids and bases contain ions that interact with water. According to the Arrhenius definition, acids are substances that produce hydrogen ion in water while bases are substances that produce hydroxide ion in water.

The pH scale is a graphic description of the hydrogen or hydroxide ion present in a sample. Since pH= -log[H^+], the higher the pH , the lower the hydrogen ion concentration and vice versa.

Similarly, pOH= -log [OH^-] , hence the more the OH^- concentration the lower the pOH.

However pH + pOH =14.

Thus the concentration of hydrogen or hydroxide ions present determines the pH of any solution.

Explanation:

It is given that,

Number of mol of Neon is 2 mol

Temperature, T = 308 K

Mass, m = 0.02 kg

Value of R - 8.31 J/mol-K

We need to find the average velocity of atoms in 2.00 mol of neon. Neon is a monoatomic gas. Let v is the velocity. So,

[tex]\dfrac{1}{2}mv^2=\dfrac{3}{2}nRT\\\\v=\sqrt{\dfrac{3nRT}{m}} \\\\v=\sqrt{\dfrac{3\times 2\times 8.314\times 308}{0.02}} \\\\v=876.47\ m/s[/tex]

A ladder rests in limiting equilibrium against a rough vertical wall and with its foot on rough horizontal ground, the coefficient of friction at both points of contact being 0.5. The ladder is uniform and weighs 300N. Find the angle which the ladder makes with the horizontal ground. Find also the normal reactions at the wall and the ground.

Answers

Answer:

θ = 36.9°

N = 240 N

R = 120 N

Explanation:

Draw a free body diagram.  There are five forces on the ladder:

Weight force mg pulling down at the center of the ladder,

Normal force N pushing up at the ground,

Friction force Nμ pushing right at the ground,

Reaction force R pushing left at the wall,

and friction force Rμ pushing up at the wall.

Sum of forces in the x direction:

∑F = ma

Nμ − R = 0

R = Nμ

Sum of forces in the y direction:

∑F = ma

N + Rμ − mg = 0

N + Nμ² − mg = 0

N (1 + μ²) = mg

1 + μ² = mg / N

Sum of torques about the base of the ladder.

∑τ = Iα

mg (L/2 cos θ) − R (L sin θ) − Rμ (L cos θ) = 0

mg (L/2 cos θ) = R (L sin θ) + Rμ (L cos θ)

mg (1/2 cos θ) = R (sin θ + μ cos θ)

mg / 2 = R (tan θ + μ)

mg / (2R) = tan θ + μ

Substitute:

mg / (2Nμ) = tan θ + μ

(1 + μ²) / (2μ) = tan θ + μ

(1 − μ²) / (2μ) = tan θ

Given μ = 0.5:

tan θ = (1 − 0.5²) / (2 × 0.5)

tan θ = 0.75

θ = 36.9°

The reaction forces are:

N = mg / (1 + μ²) = 240 N

R = Nμ = 120 N

It is 120n I hope this helpsss
