Answer:

It can cause an object to accelerate.

It can cause an object to stop moving.

It can cause an object to start moving.

It can cause an object to change directions.

Explanation:

When the velocity of an object is increased in the same direction, the object is said to have positive acceleration. If it increases its velocity in a direction that is opposite to the original direction, it is negative acceleration.

When an object that's already moving is made to stop, it is said to have decelerated. Deceleration is negative acceleration.

When an object at rest is made to move by applying a force, it is said to have accelerated to some final velocity, during its motion for some duration.

An object at rest will remain at rest is said to have no net force acting on it.

Explanation: simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The time interval of each complete vibration is the same. The force responsible for the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. That is, F = −kx, where F is the force, x is the displacement, and k is a constant. This relation is called Hooke’s law.

A specific example of a simple harmonic oscillator is the vibration of a mass attached to a vertical spring, the other end of which is fixed in a ceiling. At the maximum displacement −x, the spring is under its greatest tension, which forces the mass upward. At the maximum displacement +x, the spring reaches its greatest compression, which forces the mass back downward again. At either position of maximum displacement, the force is greatest and is directed toward the equilibrium position, the velocity (v) of the mass is zero, its acceleration is at a maximum, and the mass changes direction. At the equilibrium position, the velocity is at its maximum and the acceleration (a) has fallen to zero. Simple harmonic motion is characterized by this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position. Furthermore, the interval of time for each complete vibration is constant and does not depend on the size of the maximum displacement. In some form, therefore, simple harmonic motion is at the heart of timekeeping.

The maximum velocity is 48π m/s.

The equation: can be used to determine the maximum velocity of a particle in simple harmonic motion.

Vmax = ω * A

Where

The following formula can be used to get the angular frequency:

ω = 2π / T

Where

T is the motion's period.

Given that the period is π/2 seconds (T = π/2) and the amplitude is 12 m (A = 12), we can find the angular frequency:

ω = 2π / (π/2) = 4π rad/s

Now we can calculate the maximum velocity:

Vmax = ω * A = (4π rad/s) * (12 m) = 48π m/s

Therefore, the maximum velocity is 48π m/s.

Explanation:

When you start pushing or pulling a stationary object with a constant force, it starts to move if the force you exert is greater than the net forces resisting the movement, such as friction and gravity. If the object starts to move at some speed, it will acquire kinetic energy. Kinetic energy is the energy an object has because of its motion.

Kinetic energy is the force that moves an object. If we want to accelerate something, we must apply a force.

Energy can take on a variety of shapes. Examples of these include: electric power, sound energy, energy source, nuclear and atomic energy, radiant energy, generate heat, mechanical energy, gravity, and so on. Each form has the ability to shift or transform into the others.

The term "energy" was initially employed in the realm of physics by Thomas Young (1773–1829), but it didn't catch on. Thomas Young later utilized interference experiments to demonstrate that light is a wave.

The work done on an object moving from position (x1, y1) to (x2, y2) under an applied force F is given by the work integral:

W = ∫ F ⋅ dr

where dr is the displacement vector from position (x1, y1) to (x2, y2).

For the given scenario, the applied force is F = (x^2 + y^2)i + (x^2 + y^2)^(1/2)j, and the displacement is from (4,0) to (0,4), which is given by dr = (-4, 4)i + (0, 4)j.

So, the work done is:

W = ∫ F ⋅ dr = ∫ ((x^2 + y^2)i + (x^2 + y^2)^(1/2)j) ⋅ ((-4)i + (4)j)

= ∫ -4x^2 - 4y^2 + 4(x^2 + y^2)^(1/2) dx

Explanation:

Functionalism: According to functionalism, social inequality is necessary for the smooth functioning of society. This means that even if all the world's wealth and assets were equally divided, people's skills, abilities, and efforts would still differ, leading to differences in income and wealth. Moreover, social positions that require more education, training, and skills would still be rewarded more highly than those that require less. Therefore, some people would still be motivated to achieve more than others and occupy higher social positions. Additionally, some people might not want to work hard and would be content with their share, while others might want to invest their share and accumulate more wealth. This would lead to differences in wealth and income over time, leading to the re-emergence of social stratification.

Conflict Theory: According to conflict theory, social inequality is the result of the struggle for power and resources between different social groups. Even if all the world's wealth and assets were equally divided, some people or groups would still try to monopolize the resources and accumulate more wealth and power than others. For example, some people might try to control the means of production, such as land, factories, and capital, while others might try to control the distribution of goods and services, such as markets, transportation, and communication. Moreover, some people might have more social and cultural capital, such as education, networks, and prestige, which would give them an advantage in achieving their goals. Therefore, social stratification would still exist, but in different forms and with different justifications.

Interactionism: According to interactionism, social inequality is the result of the symbolic meanings and interpretations that people attach to wealth, status, and power. Even if all the world's wealth and assets were equally divided, people would still have different attitudes, values, and beliefs about them, which would affect their behavior and interactions. For example, some people might feel more entitled to a higher share of the wealth and assets because of their race, gender, religion, or nationality, while others might feel less entitled or even resentful. Moreover, some people might use their wealth and assets as symbols of their identity, status, and prestige, while others might reject them as meaningless or corrupt. Therefore, social stratification would still exist, but in different symbolic forms and meanings.

Response to Post 1:

I agree with your analysis from the perspective of functionalism.

The net force in Newtons of the object is 10N.

Solution:

m1 = 4kg

a = 2.5m/s²

Force m = ma

F = 4 * 2.5 = 10N.

The greater the net force acting on an object the greater its acceleration. Newton's second law of motion summarizes these relationships. We can rewrite the acceleration equation above to find the net force. The net force on an object is the combined effect of all compressive and tensile forces actually acting on the object.

When the forces pushing or pulling an object are unbalanced the object accelerates in the direction of the net force. The net force is the sum of all the individual forces acting on an object.

Answer:

5.67 m/s

Explanation:

The speed of a wave can be calculated as the distance traveled by the wave divided by the time taken:

Speed = Distance/Time

In this case, the distance traveled by the wave is the length of the pool, which is 17 m. The time taken by the wave to travel this distance is 3 seconds.

So, the speed of the wave can be calculated as:

Speed = 17 m/3 s

Speed = 5.67 m/s

Therefore, the speed of the water wave in the 17 m long pool is 5.67 m/s.

Given that two large parallel plates are separated by 0.20 m and that the potential difference is 12V.

(a) Describe the motion of an electron released from rest at a distance "d" from the negative plate.

(b) What distance from the positive plate will the electron have a speed of 1 x 10^6 m/s?

For part (a):

The magnitude of an electric field can be given as  \(||\vec E||=\frac{\Delta V}{d}\), where "ΔV" is the potential difference and "d" is the distance between the plates.

So, \(||\vec E||=\frac{12 \ V}{0.20 \ m} \Longrightarrow \boxed{||\vec E||=60 \ \frac{N}{C} }\)

An electric field is created between the plates pointing from positive towards negative. We know that negative charges accelerate opposite the direction of electrical fields. So the electron placed "d" meters away from the negative plate will accelerate towards the positive plate at a constant rate.

For part (b):

We know that...

- the charge of an electron is \(\bold{-1.602 \times10^{-19} \ C}\).

- the mass of an electron is \(\bold{9.11 \times10^{-31} \ kg}\).

- \(\vec F_e=q\vec E\)

- \(\vec F =m\vec a\)

\(\Longrightarrow \vec F_e=(-1.602 \times10^{-19} \ C)(60 \ \frac{N}{C} }) \Longrightarrow \boxed{\vec F_e= -9.612 \times10^{-18} \ N}\)

\(\Longrightarrow \vec F =m\vec a \Longrightarrow \vec a=\frac{\vec F}{m} \Longrightarrow \vec a=\frac{-9.612 \times10^{-18}}{9.11 \times10^{-31} \ kg} \Longrightarrow \boxed{\vec a=-1.06 \times10^{13} \ m/s^2}\)

Kinematic Equation: \(\vec v_f^2=\vec v_0^2+2\vec a \Delta \vec x\)

\(\Longrightarrow 1 \times10^{12} \ m^2/s^2=-2.11 \times10^{13} \ m/s^2 \Delta \vec x \Longrightarrow \Delta \vec x= \frac{1 \times10^{12} \ m^2/s^2}{-2.12 1\times10^{13} \ m/s^2}\)

\(\Longrightarrow \boxed{\Delta \vec x= -0.047 \ m}\)

The distance from the positive plate we'll call, "D."

\(D=0.20+\Delta \vec x\)

\(\Longrightarrow D=0.20+\Delta \vec x \Longrightarrow D=0.20 \ m+(-0.047 \ m) \Longrightarrow \boxed{D=0.153 \ m} \therefore Sol.\)

Explanation:

We want to calculate the acceleration of the car. Acceleration is the change in velocity over the change in time.

\(a= \frac{ \Delta v}{\Delta t}\)

The change in velocity is the difference between the final velocity and the initial velocity.

\(a= \frac{v_f-v_i}{\Delta t}\)

The car speeds up from 80 meters per second to 90 meters per second. Therefore,

Substitute these values into the formula.

\(a= \frac {90 \ m/s - 80 \ m/s}{2 \ s}\)

Solve the numerator and subtract.

\(a= \frac{10 \ m/s}{2 \ s}\)

Divide.

\(a= 5 \ m/s/s\)

\(a= 5 \ m/s^2\)

The acceleration of the car is 5 meters per second squared.

The coefficient of static friction places a limit of approximately 3.42 seconds on the minimum time required for the car to accelerate from rest to 60.0 mph (26.8 m/s).

To find the limit that the coefficient of static friction places on the minimum time required for a car to accelerate from rest to 60.0 mph (26.8 m/s), we need to consider the maximum acceleration the car can achieve due to the friction between the rear tires and the pavement.

The maximum acceleration can be determined using the formula:

a_max = μs * g

where μs is the coefficient of static friction and g is the acceleration due to gravity (approximately 9.8 m/s²).

In this case, since the car's engine only turns the two rear wheels, the maximum acceleration is limited by the friction force between the rear tires and the pavement.

Now, to calculate the minimum time required to accelerate to 60.0 mph (26.8 m/s), we can use the following kinematic equation:

v = u + a * t

where v is the final velocity (26.8 m/s), u is the initial velocity (0 m/s), a is the acceleration, and t is the time.

Rearranging the equation, we have:

t = (v - u) / a

Plugging in the values, we get:

t = (26.8 m/s - 0 m/s) / a_max

t = 26.8 m/s / (μs * g)

Substituting the given value for the coefficient of static friction (μs ≈ 0.800) and the acceleration due to gravity (g ≈ 9.8 m/s²), we can solve for the minimum time required:

t = 26.8 m/s / (0.800 * 9.8 m/s²)

t ≈ 3.42 seconds

Therefore, the coefficient of static friction places a limit of approximately 3.42 seconds on the minimum time required for the car to accelerate from rest to 60.0 mph (26.8 m/s).

The width of the central bright band is approximately 0.21578 radians. The width of the central bright band can be determined by using the formula for the angular position of the mth order maximum θ = λ / w

To determine the width of the central bright band when light at 410 nm shines through a slit with a width of 3.8 × 10^−6, we can apply the principles of diffraction and interference.

The width of the central bright band can be determined by using the formula for the angular position of the mth order maximum:

θ = λ / w

where θ is the angular position, λ is the wavelength of the light, and w is the width of the slit.

Given:

Wavelength of the light, λ = 410 nm = 410 × 10^−9 m

Width of the slit, w = 3.8 × 10^−6 m

Substituting the values into the formula, we have:

θ = (410 × 10^−9 m) / (3.8 × 10^−6 m)

θ = 0.10789 radians

To find the width of the central bright band, we can use the relationship:

Width of the central bright band = 2θ

Width of the central bright band = 2 × 0.10789 radians

Width of the central bright band = 0.21578 radians
