The pressure transmitted in the hydraulic fluid is 4000 Pa and the mass of the load is 40.82 kg.

To determine the pressure transmitted in the hydraulic fluid, we can use the formula:

Pressure = Force / Area

Given that a force of 20 N is applied to the small piston and the cross-sectional area of the small piston is 0.005 m², we can calculate the pressure as follows:

Pressure = 20 N / 0.005 m²

Pressure = 4000 Pa

Therefore, the pressure transmitted in the hydraulic fluid is 4000 Pa.

To determine the mass of the load, we need to consider the equilibrium of forces in the hydraulic system. The force applied to the small piston is transmitted to the larger piston. Since the system is in equilibrium, the force exerted by the larger piston must balance the force applied to the small piston.

Using the formula:

Force = Pressure × Area

The force exerted by the larger piston can be calculated as follows:

Force = Pressure × Area (large piston)

Force = 4000 Pa × 0.1 m²

Force = 400 N

Therefore, the force exerted by the larger piston is 400 N.

Since force is equal to mass multiplied by acceleration (F = m × a), and the acceleration due to gravity is approximately 9.8 m/s², we can calculate the mass of the load:

400 N = mass × 9.8 m/s²

Solving for the mass:

mass = 400 N / 9.8 m/s²

mass ≈ 40.82 kg

Therefore, the mass of the load is approximately 40.82 kg.

The process involves using the Mach angle formula and the Prandtl-Meyer function, along with the isentropic relation for supersonic flow.

To calculate the deflection angle of the corner in a supersonic flow, we can use the Prandtl-Meyer expansion theory.
Given the initial Mach number (m1) of 1.58 and the initial pressure (p1) of 1 atm, we need to find the deflection angle.
First, we can use the Mach angle formula:
Mach angle (θM) = arcsin(1/m1)
Substituting the given Mach number, we have:
θM = arcsin(1/1.58)
Using a calculator, we find that θM is approximately 37.1 degrees.
Next, we can use the Prandtl-Meyer function to find the Mach angle downstream of the corner (θ2). The Prandtl-Meyer function relates the Mach angles before and after the expansion.
The Prandtl-Meyer function is defined as:
ν(M) = √((γ+1)/(γ-1)) * arctan(√((γ-1)/(γ+1)*(M²-1))) - arctan(√(M²-1))
where γ is the ratio of specific heats and M is the Mach number.
To find θ2, we can rearrange the equation and solve for M2 (Mach number downstream of the corner):
M2 = √(1 + (ν2/√((γ+1)/(γ-1))))
Since ν1 = θM and ν2 = θ2, we can rewrite the equation as:
M2 = √(1 + (θ2/√((γ+1)/(γ-1))))
Now, we can find the Mach number downstream of the corner using the given pressure downstream (p2 = 0.1306 atm) and the ratio of specific heats (γ).
Using the isentropic relation for supersonic flow:
(p2/p1) = (1 + ((γ-1)/2)*M2²)^(γ/(γ-1))
Substituting the given values, we have:
(0.1306/1) = (1 + ((γ-1)/2)*M2²)^(γ/(γ-1))
Solving this equation will give us the Mach number downstream of the corner (M2).
Finally, using the equation:
θ2 = ν2 - ν1
we can find the deflection angle (θ2) by subtracting the Mach angle before the corner (θM) from the Mach angle downstream of the corner (θ2).
In conclusion, to calculate the deflection angle of the corner in a supersonic flow, we can use the Prandtl-Meyer expansion theory. By finding the Mach angle before and after the corner, and subtracting them, we can determine the deflection angle. The process involves using the Mach angle formula and the Prandtl-Meyer function, along with the isentropic relation for supersonic flow. By substituting the given values, we can find the Mach number downstream of the corner and calculate the deflection angle.

The earth could not be broken apart by the impactor since it was formed of such light material (mostly gas and liquid).

According to the Giant Impact Hypothesis, which is the most widely accepted theory for how the moon formed, the Earth and a Mars-sized object called Theia collided with each other as they were forming as protoplanets. The moon was created from a large amount of debris. According to this theory, the Moon was created after the Earth collided with a smaller planet that was around Mars' size. The Moon was created when the impact's leftover debris gathered in an orbit around Earth.

The larger body may have caught the iron core of the striking object.

5. At 3 inches from the speaker: Intensity ≈ 1.59 x 10^(-6) watts.

10. At 1 meter from the speaker: Intensity ≈ 9.25 x 10^(-9) watts, dB level ≈ 37.58 dB.

To calculate the intensity of the sound in watts and the dB level at different distances from the speaker, we can use the inverse square law for sound propagation. The inverse square law states that the intensity of sound decreases with the square of the distance from the source.

Given:

First, let's calculate the intensity (I1) in watts at a distance of 3 inches (0.0762 meters) from the speaker:

I1 = 10^((dB - 120) / 10)

= 10^((62 - 120) / 10)

= 10^(-5.8)

≈ 1.59 x 10^(-6) watts

Now, let's proceed to the next part of the question:

Distance from the speaker (D2) = 1 meter

We need to find the intensity (I2) and the dB level at this distance.

Using the inverse square law, we can calculate the intensity (I2) at a distance of 1 meter:

I2 = I1 * (D1 / D2)^2

= (1.59 x 10^(-6) watts) * ((0.0762 meters / 1 meter)^2)

= (1.59 x 10^(-6)) * (0.0762^2)

≈ 9.25 x 10^(-9) watts

To find the dB level at a distance of 1 meter, we can use the formula:

dB = 10 * log10(I / I0)

where I is the intensity and I0 is the reference intensity (usually taken as 10^(-12) watts).

dB2 = 10 * log10(I2 / I0)

= 10 * log10((9.25 x 10^(-9)) / (10^(-12)))

= 10 * log10(9.25 x 10^3)

≈ 37.58 dB

Therefore, the answers to the given questions are:

(5) The intensity of the sound at a distance of 3 inches from the speaker is approximately 1.59 x 10^(-6) watts.

(10) The intensity of the sound at a distance of 1 meter from the speaker is approximately 9.25 x 10^(-9) watts, and the corresponding dB level is approximately 37.58 dB.

When a beam of 11 keV X-rays illuminates a sample, the angles that will produce diffraction maxima of the first, second, and third order can be calculated using Bragg's law, which states that nλ = 2d sin(θ), where n is the order of diffraction, λ is the wavelength of the X-rays, d is the spacing between crystal lattice planes, and θ is the angle of incidence.

Bragg's law can be used to calculate the angles for diffraction maxima. For the first-order maximum (n = 1), we have λ = 2d sin(θ₁). Rearranging the equation, we get sin(θ₁) = λ / (2d). Substituting the values, with λ representing the wavelength of 11 keV X-rays (which can be converted to the corresponding wavelength), and the known spacing between lattice planes, we can solve for θ₁.

For the second-order maximum (n = 2), the equation becomes λ = 2d sin(θ₂). Solving for sin(θ₂) and substituting the values, we can find θ₂.

Similarly, for the third-order maximum (n = 3), we use λ = 2d sin(θ₃) to determine sin(θ₃) and find θ₃ by substituting the values.

The source of protons that are pumped out of the mitochondrial matrix in Stage 1 of oxidative phosphorylation is NADH (A).

During Stage 1, electrons from NADH are passed through the electron transport chain (ETC) and this process results in the pumping of protons across the inner mitochondrial membrane from the matrix to the intermembrane space. This proton gradient is then used by ATP synthase to generate ATP during Stage 2 of oxidative phosphorylation.

FADH can also donate electrons to the ETC, but it does not contribute as many protons to the gradient as NADH. H₂O and H₂S are not involved in the electron transport chain or the proton pumping process during oxidative phosphorylation.

My answer to research question one is a car with a higher mass has more inertia than a car with a lower mass. A car with a higher mass needs more force to move than a car with a lower mass. The advantage of a car with greater mass is that it takes less impact when crash happens and has more protection.

The advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.

The disadvantage of a race car with large mass is that it will be difficult to get it start moving.

The Newton's first law of motion states that, an object in a state of rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This first law is also known as law of inertia because it depends on mass of the object.

Inertia is reluctance of an object to move or stop moving once it is in motion.

Thus, the advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.
