Answer : F = 9800 N

Explanation :

It is given that,

The spring constant  for the industrial scale at the junkyard, k = 39,200 N/m

Displacement of spring, x = 25 cm = 0.25 m

According to Hooke's law, the force applied on spring is given by the following relation :

F = -k x

Negative sign shows the force is applied in opposite direction.

[tex]F = -39,200\ N/m\times 0.25\ m[/tex]

So, [tex]F=-9800\ N[/tex]

[tex]|F|=9800\ N[/tex]

Hence, this is the required solution.

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

Basically Randy made a hypothesis by which he thinks that he has an idea but he is not sure about that.

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.

5.09 m/s.

Correct On EDG

If the rock has a mass of 1 kg then the speed of the rock would have been 19.6 m / s after it has fallen for two seconds.

There are three equations of motion given by  Newton ,

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem If the rock has a mass of 1 kg , we have to find out  which is the speed of the rock after it has fallen for two seconds

By using the second equation of the motion for the vertical direction,

v = u + gt

v = 0 + 9.8 × 2

v = 19.6 m / s

Thus , If the rock has a mass of 1 kg then the speed of the rock would have been 19.6 m / s after it has fallen for two seconds.

Answer:

Explanation: Increasing friction between surface have so many good reasons such as - generating more heat between surfaces, avoiding slippage from smooth surfaces, reducing speed of vehicles. Friction force is the force automatically acting in opposite direction of motion. Friction can be dry friction force and fluid friction force depending upon the medium of motion of object.

Using the principles of projectile motion, we calculate the horizontal distance travelled by Adam using his initial velocity, launch angle, and the constant for gravitational acceleration.

To calculate the distance Adam lands from his initial position, we need to use the principles of physics, specifically those of projectile motion. The horizontal distance (range) in a projectile motion can be calculated using the formula R = (v²sin(2θ))/g, where v is the initial velocity, θ is the launch angle, and g is the gravitational acceleration (9.8 m/s²).

Substituting the given values, we get R = ((30 m/sec)²sin(2*25))/9.8 m/s². This should give you the horizontal distance Adam travels in meters.

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.

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.
