how does narveson incorporate a mathematical ""multiplier"" into his argument?

Red Cell is 300 times larger than the virus.

The discocyte shape of human RBCs is approximately 7.5 to 8.7 μm in diameter and 1.7 to 2.2 μm in thickness.

The mean diameter of blood cells is determined by using the wave length of laser light λ = 632,2nm.

According to Rayleigh's expression (William Strutt) cell diameter d can be written as d = 1.22 λ/ tanθ. By replacing tanθ the equation for erythrocyte diameter d is obtained: d = n·λ·L/r 1.

Answer:

\(F_A =5.625*10^1^6N\)

Explanation:

From the question we are told that

50,000 years ago,

A giant 4.5 107-kg meteor

180-m-deep hole

20,000 m/s

Generally for this problem the energy change is given as

       \(\triangle E=\frac{1}{2} mv^2 +mgd\)

Having the potential and kinetic energy in place

Mathematically  solving for Average force\(F_A\)

       \(\triangle E=F_a*d\)

\(F_A =\frac{1/2* 4.5*10^7(20,000)^2-kg+4.5*10^7*9.81*160}{160}\)

Therefore Average force \(F_A\) is given by

\(F_A =5.625*10^1^6N\)

The resulting changes will be:

1. Pressure head: 88 ft (or 26.82 m)

2. Effective stress: No change, assuming no other factors affect it

3. Fluid pressure: No change

4. Total stress: Decreased by the same amount as the effective stress

To calculate the effective stress in the aquifer, we need to subtract the fluid pressure from the total stress.

Given:

Pressure head in the aquifer = 100 ft (or 30.48 m)

The pressure head in the aquifer is directly proportional to the fluid pressure, which can be calculated using the formula:

Fluid pressure (P) = ρ * g * h

Where:

ρ = density of the fluid (water) = approximately 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = pressure head

Fluid pressure = 1000 kg/m³ * 9.8 m/s² * 30.48 m ≈ 298,440 N/m² (or Pa)

The total stress in the aquifer is the sum of the fluid pressure and the effective stress. Therefore, the effective stress can be calculated by subtracting the fluid pressure from the total stress.

Now, let's consider the changes in the hydraulic head due to pumping:

Change in hydraulic head = -12 ft (or -3.66 m)

The resulting changes in each parameter will be as follows:

1. Pressure head:

The pressure head will be reduced by 12 ft, so the new pressure head will be 100 ft - 12 ft = 88 ft (or 26.82 m).

2. Fluid pressure:

The fluid pressure does not change, as it depends on the density of the fluid and the acceleration due to gravity, which remain constant.

3. Effective stress:

The effective stress can be calculated as the total stress minus the fluid pressure. Since the fluid pressure remains constant, the effective stress will also remain constant unless there are other factors affecting it.

4. Total stress:

The total stress is the sum of the fluid pressure and the effective stress. As mentioned earlier, the fluid pressure remains constant, so the total stress will decrease by the same amount as the effective stress, assuming no other factors affect the total stress.

Therefore, the resulting changes will be:

1. Pressure head: 88 ft (or 26.82 m)

2. Effective stress: No change, assuming no other factors affect it

3. Fluid pressure: No change

4. Total stress: Decreased by the same amount as the effective stress

The weight has no kinetic energy at the top of the lift when it is overhead because it is briefly immobile. Potential energy makes up the entirety of the system's energy. As the weight increases, the kinetic energy will rise.

The potential energy of  system increases by an amount equal to  work done against gravity, which is provided by the product of the weight,  height, and the acceleration due to gravity, when a person lifts a 95 kg weight to a height of 2.13 m. The potential energy gained by the weight in this instance is provided by:

Potential energy = weight x height x gravity

Potential energy = 95 kg x 2.13 m x 9.81 m/s^2

The maximum possible efficiency of an engine operating between the given two temperatures is 10.38%.

Maximum efficiency that is obtained when the heat engine is operating between two temperatures is called Carnot Efficiency.

The efficiency of heat engines generally increases with the operating temperature. Advanced structural materials that helps engines to operate at higher temperatures is an active area of research.

The efficiency of Carnot engine = 1

No engine has 100 % efficiency as per the Kelvin Planck statement. Sink temperature is always  less than the source temperature, therefore  of Carnot cycle efficiency becomes less than 100 %.

Given T1 = 35°C , T2= 3°C

Efficiency =( (T1 - T2)/T1) × 100

T1= 35+273 = 308 K

T2 = 3 +273= 276 K

Efficiency = ( 308 - 276)/308×100

When in total lunar eclipse, the moon shows a reddish color because only the red light from the Sun is deflected onto it by the Earth's atmosphere.

Hence, the correct option is B.

During a total lunar eclipse, the Earth comes between the Sun and the Moon, casting a shadow on the Moon. However, even when in the shadow, the Moon does not become completely dark. Instead, it takes on a reddish hue. This occurs due to a phenomenon called atmospheric scattering.

When sunlight passes through the Earth's atmosphere, it undergoes scattering, with shorter wavelengths (blue and green light) being scattered more than longer wavelengths (red and orange light). As the Earth's atmosphere refracts or bends the sunlight, it directs the longer red wavelengths toward the Moon.

This red light is then deflected onto the Moon's surface during a lunar eclipse, giving it a reddish appearance. Essentially, the Earth's atmosphere acts as a lens that filters out most of the other colors of light, allowing predominantly red light to reach the Moon and be observed during the eclipse.

Therefore, the correct explanation for the Moon's reddish color during a total lunar eclipse is that only the red light from the Sun is deflected onto it by the Earth's atmosphere.

Hence, the correct option is B.

Answer: 121.2 m/s

Explanation:

Here we will use the conservation of energy.

We can write the total energy of an object as:

E = K + U

For this particular case we have:

K = kinetic energy = (m/2)*v^2

U = potential energy = m*g*h

where:

m = mass of the object.

g = gravitational acceleration = 9.8m/s^2

h = height at which the object is dropped, in this case 750m

v = velocity of the object.

Right when the packet is dropped, it's velocity is equal to zero, this means that there is no kinetic energy and only potential energy, then we have:

Ei = Ui = m*9.8m/s^2*750m = m*(7350m^2/s^2)

And when the object is about to hit the ground, h will be almost equal to zero, this will mean that we will have only kinetic energy, and because of the conservation of energy, this final energy must be the same as the initial energy, then we will have

Ei = Ef

m*(7350m^2/s^2) = Ef = Kf

m*(7350m^2/s^2) = (m/2)*v^2

We can divide by m in both sides to get:

(7350m^2/s^2) = (1/2)*v^2

√( 2*(7350m^2/s^2)) = v = 121.2 m/s

Then the velocity of the packet when it reaches the ground is 121.2 m/s

Answer:

The car moving with speed 50 mph

Explanation:

We are given that

Distance, s=280 feet=85.3 m

1 feet=0.3048 m

Coefficient of kinetic friction=\(\mu_s=0.3\)

1 m/s=2.237 mph

We have to find the speed of car moving.

Speed, v=\(\sqrt{2\mu_s gs}\)

Where \(g=9.8ms^{-2}\)

Using the formula

Speed of the car,v=\(\sqrt{2\times 0.3\times 9.8\times 85.3}\)

Speed of the car,v=22.4 m/s

Speed of the car, v=\(22.4\times 2.237\approx 50 mph\)

Hence, the car moving with speed 50 mph

The average translational kinetic energy of one of the molecules of the given ideal gas is 4,651.683 J

The temperature of the gas = 100°C

So the temperature of the gas in terms of kelvin = 373 K

The average translational kinetic energy can be found using the formula,

                 K = 3/2 RT

where K is the average translational kinetic energy

           R is the gas constant

           T is the temperature in kelvin

Let us substitute the known values in the above equation, we get

              K = 3/2 x 8.314 x 373

                 = 9,303.366 / 2
