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.

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.

Both Thomson and Rutherford used charged particles in their experiments.

Explanation:

The x-component of the vector is 36.55 m.

The components of a vector include both x and y components. The x-component is determined along x-axis, while y-component is determined along y-axis.

Vx = Vcosθ

Vy = Vsinθ

where;

The x-component of the vector is calculated as follows;

x = 47.3 x cos(39.4)

x = 36.55 m

Thus, the x-component of the vector is 36.55 m.

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]

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

The correct answer is Potential energy from intermolecular forces.

Potential energy from intermolecular forces is part of the internal energy of a substance, therefore the correct option is D.

It is the total energy of the substance that is contained in the system which is the sum of all the kinetic energy and potential energy of the molecules and the atoms contained in it.

The potential energy of the intermolecular forces is also part of the internal energy of the substance.

Standards provide people and organizations with a basis for mutual understanding, and are used as tools to facilitate communication, measurement, commerce and manufacturing. Standards are everywhere and play an important role in the economy, by: facilitating business interaction.

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.

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.

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.

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]

So, the correct option is (B).

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
