Answer:

A) one

Explanation:

for anyone else who looks for this question, the answer is one. stated in the book itself, "a conversion factor is a ratio that has a value of one."

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]

The gravitational force between two planets would increase by a factor of nine if the masses of both planets are tripled, while the distance between them stays the same.

The student is asking about the effect on gravitational force when the masses of two planets are tripled but the distance between them remains constant. According to Newton's law of gravity, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

If both masses are tripled, the gravitational force becomes 3  imes 3 times larger because the force depends on the product of the two masses. Since the distance does not change, the ratio of the gravitational force after tripling the masses would be 9:1 when compared to the initial force (3 imes 3 = 9). Therefore, the gravitational force increases by a factor of nine

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.

The relationship between frequency and wavelength of light is given by:

[tex]f=\frac{c}{\lambda}[/tex]

where

f is the frequency

c is the speed of the light

[tex]\lambda[/tex] is the wavelength

Therefore, from this equation we see that frequency is inversely proportional to wavelength: the longer the wavelength, the smaller the frequency, and the shorter the wavelength, the higher the frequency.

The wavelength and frequency of light are inversely proportional to each other. The higher the frequency of light, the shorter its wavelength. Also, high-frequency waves carry more energy than lower-frequency waves.

The wavelength and frequency of light are inversely proportional to each other. This means if the wavelength of light increases, its frequency decreases, and vice versa. This relationship can be expressed as λf = c, where λ represents wavelength, f represents frequency, and c is the speed of light. For instance, the different colors of visible light have specific frequencies and wavelengths associated with them. Radio waves, which have longer wavelengths, have lower frequencies, while visible light with shorter wavelengths have higher frequencies. This relationship remains constant irrespective of the moving source or observer.

In a given medium under fixed conditions, the higher the frequency, the smaller the wavelength. Also, waves with higher frequencies carry more energy than lower-frequency waves. This energy is delivered as elementary particles called photons. Therefore, higher-frequency waves deliver more energetic photons compared to lower-frequency waves.

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.

Final answer:

The friction force impeding the box's motion is 4.24 N. The coefficient of friction is 0.106.

Explanation:

To find the friction force impeding the motion of the box, we need to use the equation:

Ffriction = μmgcosθ

Where Ffriction is the friction force, μ is the coefficient of friction, m is the mass of the box, g is the acceleration due to gravity, and θ is the angle of the incline.

Using the given values, we can substitute them into the equation:

Ffriction = (0.0300)(18.0 kg)(9.8 m/s²)cos(34.0°) = 4.24 N

So, the friction force impeding the motion of the box is 4.24 N. To find the coefficient of friction, we need to rearrange the equation:

μ = Ffriction / (mgcosθ)

Substituting the known values:

μ = 4.24 N / (18.0 kg)(9.8 m/s²)cos(34.0°) = 0.106

Therefore, the coefficient of friction is 0.106.
