An axillary temperature of 100 degrees Fahrenheit taken orally would not register accurately.

Axillary temperature is taken by placing the thermometer under the arm. It is usually slightly lower than oral temperature, as it takes longer for the heat to reach the axilla. On the other hand, oral temperature is taken by placing the thermometer under the tongue, which is closer to the body's core temperature.

Therefore, an axillary temperature of 100 degrees Fahrenheit would be considered a low-grade fever, while an oral temperature of 100 degrees Fahrenheit would be a significant fever.

It is essential to take the temperature accurately, as it can help diagnose and monitor various medical conditions. Depending on the situation, the method of temperature taking may vary. Oral, rectal, and tympanic temperature readings are commonly used in clinical settings, while axillary temperature readings are more commonly used at home.

To find the position on the x-axis where the net gravitational force on a small mass would be zero, we need to consider the gravitational forces exerted by the two spheres.

Let's denote the mass of the small mass as "m", and we want to find the x-position where the net gravitational force on it is zero.

The gravitational force between the small mass and the 21.0 kg sphere is given by Newton's law of universal gravitation:

F₁ = (G * m * M₁) / r₁²

where G is the gravitational constant, M₁ is the mass of the 21.0 kg sphere, and r₁ is the distance between the small mass and the 21.0 kg sphere.

Similarly, the gravitational force between the small mass and the 13.0 kg sphere is:

F₂ = (G * m * M₂) / r₂²

where M₂ is the mass of the 13.0 kg sphere and r₂ is the distance between the small mass and the 13.0 kg sphere.

To have a net gravitational force of zero, the magnitudes of these two forces should be equal:

F₁ = F₂

Substituting the expressions for the forces:

(G * m * M₁) / r₁² = (G * m * M₂) / r₂²

Canceling out the common factors and rearranging the equation:

(M₁ / r₁²) = (M₂ / r₂²)

To find the position on the x-axis, we need to consider the distance between the small mass and each sphere. Let's denote the x-coordinate of the position we're looking for as x.

Therefore, the distances r₁ and r₂ can be calculated as follows:

r₁ = x

r₂ = |x - 20 cm|

Now, we can rewrite the equation:

(M₁ / x²) = (M₂ / (x - 20 cm)²

Substituting the known values:

(21.0 kg / x²) = (13.0 kg / (x - 20 cm)²

Now, we can solve this equation to find the position on the x-axis where the net gravitational force is zero.

By cross-multiplying and simplifying, the equation becomes:

13.0 kg * x² = 21.0 kg * (x - 20 cm)²

Expanding and rearranging the equation:

13.0 kg * x² = 21.0 kg * (x² - 40 cm * x + 400 cm²)

Simplifying further:

13.0 kg * x² = 21.0 kg * x² - 840 kg * x + 8400 kg * cm²

Now we have a quadratic equation. We can bring all terms to one side and solve for x using the quadratic formula:

8.0 kg * x² - 840 kg * x + 8400 kg * cm² = 0

Using the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a)

Here, a = 8.0 kg, b = -840 kg, and c = 8400 kg * cm².

Calculating the values under the square root: √(b² - 4ac) ≈ √((-840 kg)² - 4 * 8.0 kg * 8400 kg * cm²)

Simplifying the square root: √(705600 kg² - 268800 kg² * cm²) ≈ √436800 kg² ≈ 661.83 kg

Using the quadratic formula:

x = (-(-840 kg) ± 661

Answer:

acceleration = 0.013 m/s²

Explanation:

formula for acceleration is

a = (v-u) / t

a= (0.7-0.3) / 30

= 0.013

The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:

\(a=\frac{v-u}{t}\)

v is the final speed = 0.7m/s

u is the initial speed = 0.3m/s

t is the time taken = 30seconds

Substitute the given values into the formula:

\(a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2\)

Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

The correct answer is A. Larger diameter tires because they have more friction so you won't slide off the road.

When a vehicle is moving at high speeds, the centripetal force on the tires can be very high, causing stress on the tires. One way to reduce this stress is by using larger diameter tires. Larger diameter tires have a larger contact area with the road, which increases the amount of friction between the tire and the road. This increased friction helps to prevent the tires from sliding off the road, reducing the stress on the tires. Additionally, larger diameter tires also have a larger circumference, which means that they can cover more distance with each rotation, reducing the number of rotations needed to travel a given distance and thereby reducing the stress on the tires.

To calculate the expected fixed manufacturing costs, we need to know the fixed manufacturing costs per unit produced.

The formula for calculating the fixed manufacturing cost per unit is the Fixed manufacturing cost per unit = Total fixed manufacturing cost / Total units produced. So if we have this information, we can use the above formula to calculate the fixed manufacturing cost per unit, and then multiply it by the number of units produced and sold to get the expected fixed manufacturing costs. Let's assume we have the following information: Total fixed manufacturing cost = $60,000Total units produced = 12,000Using the formula above, we can calculate the fixed manufacturing cost per unit: Fixed manufacturing cost per unit = $60,000 / 12,000 units= $5 per unit. To find the expected fixed manufacturing costs if 18,000 units are produced and sold, we can simply multiply the fixed manufacturing cost per unit by 18,000:Expected fixed manufacturing costs = Fixed manufacturing cost per unit x Total units produced and soldExpected fixed manufacturing costs = $5 per unit x 18,000 units. Expected fixed manufacturing costs = $90,000Therefore, the expected fixed manufacturing costs will be $90,000 if 18,000 units are produced and sold.

The decay rate of the 12.0-g sample of carbon from living matter, containing radioactive 1144C, will be approximately 147 decays/minute after 1000 years and approximately 2 decays/minute after 50,000 years.

Radioactive decay follows an exponential decay model, where the decay rate decreases over time. In this case, the decay rate of the sample can be determined using the half-life of carbon-14, which is approximately 5730 years.

Step 1: Determine the decay constant (λ)

The decay constant (λ) is calculated by dividing the natural logarithm of 2 by the half-life (t½) of carbon-14:

λ = ln(2) / t½

λ = ln(2) / 5730 years

λ ≈ 0.00012097 years⁻¹

Step 2: Calculate the decay rate after 1000 years

Using the decay constant (λ), we can calculate the decay rate (R) after a given time (t) using the exponential decay formula:

R = R₀ * e^(-λ * t)

R₀ = 184 decays/minute (initial decay rate)

t = 1000 years

Substituting the values:

R = 184 * e^(-0.00012097 * 1000)

R ≈ 147 decays/minute

Step 3: Calculate the decay rate after 50,000 years

Using the same formula:

R = 184 * e^(-0.00012097 * 50000)

R ≈ 2 decays/minute

Radioactive decay is a process by which unstable atoms undergo spontaneous disintegration, emitting radiation in the process. The rate at which this decay occurs is characterized by the decay constant (λ) and is expressed as the number of decays per unit time. The half-life (t½) of a radioactive substance is the time required for half of the initial amount to decay.

The decay rate decreases over time because as radioactive atoms decay, there are fewer of them left to undergo further decay. This reduction follows an exponential pattern, where the decay rate decreases exponentially with time.

The half-life of carbon-14, used in radiocarbon dating, is approximately 5730 years. After each half-life, half of the remaining radioactive atoms decay. Therefore, in 5730 years, the initial decay rate of 184 decays/minute would reduce to approximately 92 decays/minute. After 1000 years, the decay rate would be further reduced to around 147 decays/minute, and after 50,000 years, it would decrease to approximately 2 decays/minute.

The pressure 550 feet deep behind the Glen Canyon Dam is the same as the pressure in the pipe at the level of 34th street.

The pressure at a given depth in a fluid is determined by the height of the fluid column above that point. In both cases, the water depth is 550 feet, which means the height of the fluid column is the same. Therefore, the pressure at a depth of 550 feet behind the Glen Canyon Dam is equal to the pressure at the level of 34th street in the water pipe.

This can be understood using Pascal's principle, which states that the pressure in a fluid is transmitted equally in all directions.

The statement that a negative feedback will not necessarily completely negate an initial change; it might just reduce the impact is true.

Negative feedback is a regulatory mechanism in which the output of a system counteracts a change in the input, leading to a stabilization of the system.

However, negative feedback does not necessarily completely negate an initial change. Instead, it can reduce the impact of the change and bring the system closer to its set point or desired state.

This is because negative feedback works to oppose the initial change, but it may not have enough strength to completely reverse it. In some cases, the initial change may be so large that the negative feedback can only reduce the impact, rather than completely negate it.

Overall, negative feedback is an important mechanism for maintaining stability in many biological, physical, and engineering systems.
