The question does not have enough information to find out the power gain.

The value of the power gain in dB for the circuit can be found using the formula:

Power Gain (dB) = 10 log (Output Power/Input Power)

Here, the output power is given as 20 W and the input voltage is given as 2 V. Since power is directly proportional to the square of the voltage, we can calculate the input power using the formula:

Input Power = (Input Voltage)^2/R, where R is the input resistance of the amplifier.

Without information about the input resistance, we cannot calculate the exact value of the power gain in dB. Therefore, the answer is "not enough information given".

The final temperature of the two cups of water being mixed together, given that one cup has a temperature of 30 °C and the other has 75 °C, is  58.13 °C

To obtain the final temperature of the two cups of water, we must obtain the equilibrium temperature of the two cups of water mixture. Details below:

Heat loss by cup 2 = Heat gain by cup 1

MᵥᵥC(Tᵥᵥ - Tₑ) = MC(Tₑ - T)

250 × 4186 (75 - Tₑ) = 150 × 4186(Tₑ - 30)

1046500(75 - Tₑ) = 627900(Tₑ - 30)

Clear bracket

78487500 - 1046500Tₑ = 627900Tₑ - 18837000

Collect like terms

78487500 + 18837000 = 627900Tₑ + 1046500Tₑ

97324500 = 1674400Tₑ

Divide both side by 1674400

Tₑ = 97324500 / 1674400

Tₑ = 58.13 °C

From the above calculation, the equilibrium temperature is 58.13 °C.

Thus, we can conclude that the final temperature of the two cups of water is 58.13 °C

double the force constant

Explanation:

For this exercise we see that the unit mass to the spring executes a simple harmonic motion, the maximum mechanical energy is

             Em = ½ k A²

where A is the range of motion

To double the energy we must increase the amplitude or the spring constant

Therefore, to double the total energy we must increase the amplitude by an amount √2

or we can increase the spring constant to double

The correct answer is to double the force constant

The electrostatic charge on particle 3 is 2uc * sqrt(5).

To find the electrostatic charge on particle 3, we need to consider the forces between particles. Given that the net electrostatic force on particle 2 is zero, we can conclude that the magnitudes of the forces between particle 2 and particle 1, and between particle 2 and particle 3, are equal.The electrostatic force between two charged particles is given by Coulomb's law: F = k * (|Q1| * |Q2|) / r^2, where F is the force, k is the electrostatic constant, |Q1| and |Q2| are the magnitudes of the charges, and r is the separation distance between the charges.

Let's assume that the separation between particle 2 and particle 1 is r1, and the separation between particle 2 and particle 3 is r2.Since the forces between particle 2 and particle 1, and between particle 2 and particle 3, are equal, we have:

k * (|Q2| * |Q1|) / r1^2 = k * (|Q2| * |Q3|) / r2^2

Given that |Q1| = 10uc and |Q2| = 50uc, we can rewrite the equation as:

50 * 10 / r1^2 = 50 * |Q3| / r2^2

Simplifying, we have:

r2^2 / r1^2 = 1/5

Taking the square root of both sides, we get:

r2 / r1 = 1/sqrt(5)

Since the separation distances are directly proportional to the magnitudes of the charges, we can say that |Q3| / |Q1| = r2 / r1 = 1/sqrt(5).

Substituting |Q1| = 10uc, we find:

|Q3| = (1/sqrt(5)) * 10uc = 2uc * sqrt(5)

PE = m*g*h

m = mass

g = 9.81m/s², acceleration of gravity

h = height

So m and g stay the same but the height can change so the higher you go the higher the Gravitational potential energy.

Placing a soccer ball on the top shelf increases the Gravitational potential energy

In a gravitational field the energy possessed by an object due to a change in its position called as gravitational potential energy, it is an energy that is related to gravitational force or to gravity.

When a mass of the body  (m) is moved from infinity to a point inside the gravitational influence of a source mass (M) in absence of acceleration and the amount of work done in displacing it into the source field is stored in the form of potential energy denoted with the symbol Ug.

when external force is applied, then the  position of the body changes potential energy is equal to the amount of work done on the body by the forces.

The gravitational influence on a body at infinity is zero, then the  potential energy is zero, PE = m*g*h where m = mass, g = 9.81m/s², acceleration of gravity, h = height

   The value of the acceleration of the earth toward it when it accelerates toward the earth with 9.8m/s² is a = 7.35×10-²³m/s².

  Acceleration is defined as the second derivative of displacement or the derivative of velocity:

a = d/dt(dS/dt) = dV/st.

   It is the rate of change of velocity, it generates a constant change over time.

   Forces are the definition of Newton's second law, which is stated under the relation:

∑ Force = mass × acceleration.

  In other words, force is the origin of motion since it generates acceleration in a system.

   In this case we must complete the statement:

"A student with mass 45 kg jumps off a high diving board. Using 6. 0×1024 kg for the mass of the earth, what is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9. 8 m/s2 ? assume that the net force on the earth is the force of gravity she exerts on it."

  We determine the Force of the student:

F = ma

F = 45kg * 9.8m/s².

F = 441N

  Now we go to the acceleration of the earth:

a = F/m

Someone pressed the "Hold" button. If you press it again, the multimeter should work correctly.

When the "Hold" button is pressed on a multimeter, it temporarily freezes the measurement value displayed on the screen, even if the voltage being measured changes. This can be useful if you want to take note of a specific reading without having to continually look at the screen. If the value stays at 0.00 V and an "H" is displayed, it is likely that the "Hold" button has been pressed, and pressing it again should release it and allow the multimeter to display accurate voltage readings.

According to Snell's law, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant when light passes through a boundary between two media.

This constant is known as the refractive index of the second medium, in this case, polystyrene.

The formula for Snell's law is:\(n1sin(theta1) = n2sin(theta2)\), where n1 and n2 are the refractive indices of the two media, and theta1 and theta2 are the angles of incidence and refraction, respectively, measured from the normal to the surface.

Assuming the refractive index of air is 1 (which is very close to the actual value), and the refractive index of polystyrene is 1.59, we can use Snell's law to find the angle of refraction:

sin(theta2) = (n1/n2)*sin(theta1) = (1/1.59)*sin(40) ≈ 0.393

Taking the inverse sine of both sides gives:

theta2 ≈ 23.4 degrees

Therefore, the refracted ray makes an angle of approximately 23.4 degrees with the plane of the surface.

Explanation:

The tension in the string is 48000 N.

The tension along the string is a constant and is equal to the strength of the forces exerted by the string's ends if there are no bends in the string, as there can be with vibrations or pulleys. These are the identical forces that the objects to which the string's ends are attached are applying to the ends of the string, according to Newton's third law.

V = v/2l is the fundamental frequency (n = 1). Higher frequencies are multiples of the fundamental frequency and are referred to as harmonics or overtones. The fundamental is commonly referred to as the first harmonic, followed by the second harmonic or first overtone at n = 2 and so on.

Length of the string = 0.25m

Mass of the string = 0.03 kg

Frequency = 400 Hz

L = \(\frac{1}{2} \lamda\) λ

λ = 2L

Here,

\(v = f \lambda\\\\v = f (2L)\)

Then,

\(v = \sqrt[]{} \frac{T}{\mu}\)

\(v^2 = \frac{T}{\mu}\)

\(T = v^2\mu\)

\(T = (f2L)^2\frac{m}{L\\}\\ \\T = f^24Lm\\\\T = (400)^2*4*0.25*0.30\\\\ T = 48000 N\)

When setting up the sixth harmonic, its resonant wavelength will be longer than that of the seventh harmonic.

This is because as the harmonic number increases, the wavelength decreases and the frequency increases. Therefore, the seventh harmonic has a higher frequency and shorter wavelength than the sixth harmonic.

How does wavelength change with harmonics?

For the first harmonic, the length of the string is equivalent to one-half of a wavelength. If the string is 1.2 meters long, then one-half of a wavelength is 1.2 meters long. The full wavelength is 2.4 meters long. For the second harmonic, the length of the string is equivalent to a full wavelength.
