Question 6. B) and c)

Answer:

The graph peaks at 37°C and dips beyond this point.

Explanation:

Imagine that temperature is on the x axis and rate of biological enzyme action is on y axis. Now as the temperature changes it is seen that the rate of biological enzyme action increases and is maximum at body temperature which is 37°C. Increasing the temperature does not change the rate of biological enzyme action. Which means there is no peak beyond 37°C.

In the pursuit of understanding the natural world, scientists engage in a sequence of activities known as the scientific method. This method is foundational to experimenting, observing, and learning in science. The scientific method often includes the following steps:

These steps enable a structured approach to inquiry, ensuring that conclusions are well-supported by empirical evidence. Notably, the scientific method is flexible and can vary to accommodate different scientific disciplines and types of inquiries.

Approximately 4271.9 m is the magnitude of the displacement, and its direction is approximately [tex]\( 56.14^\circ \)[/tex] north of east.

To find the displacement of the plane, we need to consider both the initial velocity of the plane and the acceleration due to the wind. Let's break down the problem into horizontal (east) and vertical (north) components:

1. Horizontal Motion (East):

  - Initial velocity [tex](\(v_{\text{initial}}\))[/tex] = 135 m/s (east)

  - Time (t) = 18.0 s

  - There is no acceleration in the east direction.

2. Vertical Motion (North):

  - Initial velocity [tex](\(v_{\text{initial}}\))[/tex] = 0 m/s (since the wind accelerates the plane only horizontally)

  - Acceleration (a) = 2.18 m/s² (north)

  - Time (t) = 18.0 s

Horizontal Motion (East):

For the horizontal motion, since there is no acceleration, the displacement [tex](\(d_{\text{east}}\))[/tex] is simply:

[tex]\[ d_{\text{east}} = v_{\text{initial}} \times t \][/tex]

[tex]\[ d_{\text{east}} = 135 \, \text{m/s} \times 18.0 \, \text{s} \][/tex]

[tex]\[ d_{\text{east}} = 2430 \, \text{m} \][/tex]

Vertical Motion (North):

For the vertical motion, we can use the equation of motion:

[tex]\[ d_{\text{north}} = v_{\text{initial}} \times t + \frac{1}{2} a t^2 \][/tex]

[tex]\[ d_{\text{north}} = 0 \times 18.0 \, \text{s} + \frac{1}{2} (2.18 \, \text{m/s}^2) \times (18.0 \, \text{s})^2 \][/tex]

[tex]\[ d_{\text{north}} = 0 + \frac{1}{2} \times 2.18 \times 18^2 \][/tex]

[tex]\[ d_{\text{north}} = \frac{1}{2} \times 2.18 \times 324 \][/tex]

[tex]\[ d_{\text{north}} = 3513.6 \, \text{m} \][/tex]

Resultant Displacement:

To find the resultant displacement, we'll use the Pythagorean theorem since the displacement vectors form a right triangle:

[tex]\[ \text{Resultant Displacement} = \sqrt{(d_{\text{east}})^2 + (d_{\text{north}})^2} \][/tex]

[tex]\[ \text{Resultant Displacement} = \sqrt{(2430 \, \text{m})^2 + (3513.6 \, \text{m})^2} \][/tex]

[tex]\[ \text{Resultant Displacement} \approx \sqrt{5904900 \, \text{m}^2 + 12346627.36 \, \text{m}^2} \][/tex]

[tex]\[ \text{Resultant Displacement} \approx \sqrt{18251527.36 \, \text{m}^2} \][/tex]

[tex]\[ \text{Resultant Displacement} \approx 4271.9 \, \text{m} \][/tex]

Direction:

To find the direction, we'll use trigonometry:

[tex]\[ \text{Direction} = \arctan \left( \frac{d_{\text{north}}}{d_{\text{east}}} \right) \][/tex]

[tex]\[ \text{Direction} = \arctan \left( \frac{3513.6 \, \text{m}}{2430 \, \text{m}} \right) \][/tex]

[tex]\[ \text{Direction} = \arctan \left( 1.445 \right) \][/tex]

[tex]\[ \text{Direction} \approx 56.14^\circ \][/tex]

The magnitude of the displacement of the plane is approximately 4271.9 m, and its direction is approximately [tex]\( 56.14^\circ \)[/tex] north of east.

Answer:

Explanation:

density is defined as the measure of the mass of a matter per unit volume. it describes the sopace occupied by a substance relative to its volume.

Density = mass ÷ volume

ρ = m ÷ v

Volume = length × width × height

Volume of lead bar = l ×  w × h

V = 25 × 1.55 × 0.5

V = 19.375cm³

mass of bar = 218.9g

ρ = 218.9 ÷ 19.375

ρ = 11.2980g/cm³

ρ = 11g/cm³

If a physician believes that foul play may have been involved in a patient's death, they would typically request a medical-legal autopsy.

If a physician believes that foul play may have been involved in a patient's death, they would typically request a medical-legal autopsy. This type of autopsy is performed to investigate the cause and manner of death, with a focus on documenting any forensic evidence that could be relevant to a legal investigation. Medical-legal autopsies differ from regular medical autopsies because they involve more detailed examination and documentation to determine if any crimes were committed.

Essentially, denman is an island.  11,000 feet is the maximum altitude of Denman Orchard.

An orchard is indeed a planned planting of shrubs or trees that is kept up for the purpose of producing food. Trees that produce fruit or nuts are often cultivated in orchards for commercial purposes.

Large gardens may include orchards as a feature, where they serve both a decorative and functional function. Although it is situated on a smaller, non-commercial scale or may emphasis berry bushes rather than fruit trees, a fruit garden and an orchard are typically interchangeable terms.

Denman Orchard reaches an altitude of about 200 yards in a fictional context, while the tallest real tree in Canada mentioned is 314 feet tall.

The maximum altitude of the fictional location known as Denman Orchard, described in a fantastical passage, is approximately 200 yards above the level plateau mentioned. This is part of an imaginative narrative and not a real-world geographical feature.

In contrast, a real-world example is provided by Randy's search for a tall tree on Vancouver Island. The tree's reported height is 314 feet, which, if accurate, would make it the tallest tree in Canada.

Explanation:

The kinetic energy (K) to rest energy (mc2) ratio for an electron traveling at 99.5% of the speed of light is approximately 150%. This is determined using the full relativistic formula, as classical mechanics significantly underestimates the required energy.

When an electron is accelerated to a speed that is 99.5% of the speed of light, relativistic effects become significant. The rest mass energy of an electron is 0.511 MeV, and at this high velocity, the kinetic energy is no longer accurately described by classical physics, and the full relativistic energy formula must be utilized. The relativistic kinetic energy of the electron is significantly greater than the classical value. If the classical kinetic energy is denoted as KEclass and the relativistic kinetic energy is denoted as KErel, the ratio KErel/KEclass is approximately 12.4. This highlights the substantial energy needed to accelerate a mass close to the speed of light, much more than classical physics would predict.

The ratio of the kinetic energy (K) to the rest energy (mc2) can be calculated using the relativistic energy equation E2 = (pc)2 + (mc2)2, where E is the total energy and p is the momentum. For an electron at 99.5% of the speed of light, this ratio is approximately 150%, meaning the kinetic energy is about one and a half times the rest mass energy. Therefore, for an electron moving at such high velocities, enormously high energies are required as indicated by currents accelerators like SLAC.

Answer:

Part a)

[tex]KE = 135.3 J[/tex]

Part b)

Factor by which KE is changed is f = 0.33

Explanation:

As we know that kinetic energy of the ball is given as

[tex]KE = \frac{1}{2} mv^2[/tex]

in order to find kinetic energy in Joule unit we need to plug in all data in SI units

so here we have

[tex]m = 5.19 oz = 0.147 kg[/tex]

now the speed of the ball is

[tex]v = 96.0 mi/h[/tex]

[tex]v = 96.0 \times \frac{1609 m}{3600 s} = 42.9 m/s[/tex]

so we will have

[tex]KE = \frac{1}{2}(0.147)(42.9)^2[/tex]

[tex]KE = 135.3 J[/tex]

Now if the speed of the ball is 55 mph

so it is

[tex]v = 55 \times \frac{1609}{3600}[/tex]

[tex]v = 24.6 m/s[/tex]

so new kinetic energy is given as

[tex]KE_2 = \frac{1}{2}(0.147)(24.6)^2[/tex]

[tex]KE_2 = 44.4 J[/tex]

So the factor by which KE is changed is given as

[tex]f = \frac{44.4}{135.3}[/tex]

[tex]f = 0.33[/tex]
