Answer:

personality disorder

Explanation:

Certain family dynamics, such as abusive parenting, can increase the susceptibility of someone developing a(n) personality disorder.

A disorder is diagnosed when these personality traits are significantly “deviated” from others and are very inflexible, impairing a person's adaptation to everyday situations and causing distress and discomfort in their personal relationships and other areas of life.

Personality disorders are generally pervasive and persistent patterns of thinking, perceiving, reacting, and relating that cause significant distress or functional impairment.

Answer:

 α= 1.3 10-5 ºC⁻¹

Explanation:

La dilatación termica de los cuerpos esta dada por la relación  

      ΔL = L₀ α ( T -T₀)

en este caso nos piden el coeficiente de dilatación térmica

     α =DL/L₀ DT

calculemos

      α = (  100,13 -100)/[100 (100 – 0)]

       α = 1,3 10-5 ºC⁻¹

Traduction

The thermal expansion of bodies is given by the relationship

       ΔL = L₀ α (T -T₀)

in this case they ask us for the coefficient of thermal expansion

        α = ΔL / L₀ ΔT

    let's calculate

        α = (100,13 -100) / [100 (100 - 0)]

        α= 1.3 10-5 ºC⁻¹

Answer:

22.2 m/s or 80 km/h

Explanation:

Given that

Distance travelled by the car, d = 240 km

Time taken by the car, t = 3 hours.

Speed of the car, v = ? m/s

for easy calculations, we will be converting the units to meters and seconds respectively.

240 km to meters would be

240 * 1000 m = 240000 m

3 hrs to seconds would be

3 * 60 mins * 60 seconds = 10800 s

now, we have our distance and time to be

d = 240000 m

t = 10800 s

speed is defined as the ratio of distance with respect to time taken, effectively,

Speed = distance/time

speed, v= 240000 / 10800

v = 22.2 m/s

therefore, the speed of the car during the time is 22.2 m/s, or if the speed is needed in km/h, we can convert it

22.2 * 3600/1000 =

80 km/h

The work was done by the force on the block of 2 kg with an acceleration gravity of  9.81 \(m/s^2\) and at an angle of \(29^o\) 42.83 J.

When an object is moved over a distance by an external force, at least some of that force must be applied in the direction of the displacement. This is known as work in physics. Work may be estimated if the force acting along the path is constant by multiplying the length of the path by the component of the force acting along the path.

To express this formally, the work W is equal to the force f times the length d, or W = fd. The work is W = fd cos if the force is applied at an angle to the displacement.

Given:

The mass, m = 2 kg,

The acceleration, g = 9.81 \(m/s^2\),

θ = angle between block and surface kinetic friction = μ

Calculate the work done by the formula given below,

\(W_{fy}\) = F sinθ

\(W_{fy}\) =  (\(mgsin\)θ)/ (sinθ -  μ * cosθ)

Substitute the values

\(W_{fy}\)  = \((2*9.81 sin29^{o} )/sin29^o - 0.30cos29^o\)

\(W_{fy}\)  = 42.83 J

Therefore, the work done by the force on the block of 2 kg with an acceleration gravity of  9.81 \(m/s^2\), and at an angle of \(29^o\) is 42.83 J.

Summary: a) The expression for the momentum of the particle can be found by the conservation of energy law. The energy gained by the particle as a result of the potential difference is the potential energy.

By conservation of energy, this energy should be equal to the kinetic energy of the particle gained by acceleration from rest. Conservation of energy implies that the initial and final total energies are equal, thus we can write:

Potential energy (U) = Kinetic energy (K) OrqV=qKqV=12mv2In this expression, q and m represent the charge and mass of the particle, respectively. v is the final velocity of the particle and V is the potential difference applied. Rearranging the above expression we get: v=2qV/m.

By using the classical momentum definition, p=mv, and replacing v in terms of q, m, and V, we get:

p=2qV.

b) The De Broglie wavelength of the particle can be obtained using the momentum expression found in part (a). Recall that the De Broglie wavelength is given by the expression: λ=h/pwhere h is the Planck constant. Replacing p with its expression we obtained in part (a), we get: λ=h/2qV

c) Since the wavelength of the particle is inversely proportional to its momentum, the particle with greater momentum will have the shorter wavelength. From the momentum expression derived above, we can see that the momentum is directly proportional to the charge of the particle. Thus, the proton which has a greater charge than the electron will have the shorter wavelength.

Answer:

2 m/s

Explanation:

Given that,

Mass of a man, m₁ = 75 kg

Mass of object, m₂ = 5 kg

Velocity of the object, v₂ = 30 m/s

We need to find the recoil velocity of the man. Let it is v₁. In the whole process, the momentum of the system will remain conserved such that,

\(m_1v_1=m_2v_2\\\\v_1=\dfrac{m_2v_2}{m_1}\\\\v_1=\dfrac{5\times 30}{75}\\\\v_1=2\ m/s\)

So, the recoil velocity of the man is 2 m/s

Answer:

C

Explanation:

The statement that best summarizes the law of conservation of energy before and after a change in a system is C. PE (initial) = PE (final) and KE (initial) = KE (final).

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This means that the total amount of energy in a closed system remains constant over time.

In statement C, the potential energy (PE) and kinetic energy (KE) of the system are conserved separately. This means that the initial potential energy is equal to the final potential energy, and the initial kinetic energy is equal to the final kinetic energy.

Statement A is incorrect because it implies that the total energy of the system changes, which violates the law of conservation of energy. Statement B is also incorrect because it implies that the potential energy and kinetic energy are equal at both the initial and final states, which may not be true in all cases. Statement D is incorrect because it combines the initial and final energies in a way that does not conserve the total energy of the system.

We can use the principle of superposition and consider the contributions from individual charges within the distribution.

Let's assume that the charge distribution consists of multiple charges q1, q2, q3, and so on. Each charge will contribute to the electric field at the desired point on the positive x-axis.

The electric field produced by a point charge (q) at a distance (r) from the charge is given by Coulomb's law:

E = k * q / r^2

Where E is the electric field, k is the electrostatic constant (k = 9 × 10^9 Nm^2/C^2), q is the charge, and r is the distance.

To calculate the y-component of the electric field at the desired point, we need to consider the y-components of each individual charge's electric field and sum them up.

The y-component of the electric field produced by each individual charge is given by:

E_y = E * sin(θ)

Where E is the electric field magnitude and θ is the angle between the line connecting the charge to the point and the positive x-axis.

By considering the contributions from all the charges in the distribution and summing up their y-components, we can determine the total y-component of the electric field at the desired point on the positive x-axis where x > a.

The statement : Compare and contrast light independent and light dependent reactions is true.

Light-independent reactions, also known as the Calvin cycle or the dark reactions, occur in the stroma of chloroplasts. They do not require light energy directly and can occur in the absence of light.

These reactions utilize the products of the light-dependent reactions, such as ATP and NADPH, to convert carbon dioxide into glucose through a series of enzyme-catalyzed reactions. The light-independent reactions are responsible for the synthesis of carbohydrates and other organic compounds.

On the other hand, light-dependent reactions occur in the thylakoid membrane of chloroplasts and require light energy. They involve the absorption of light by chlorophyll and other pigments, which excite electrons and create an electron transport chain. The energy from the excited electrons is used to generate ATP and NADPH, which are utilized in the light-independent reactions. Additionally, light-dependent reactions produce oxygen as a byproduct through the splitting of water molecules.

In summary, light-dependent reactions capture light energy and convert it into chemical energy (ATP and NADPH), while light-independent reactions utilize that chemical energy to fix carbon dioxide and synthesize carbohydrates.

Hi there!

We can use the equation:

∑F = net force (N)

m = mass (kg)

a = acceleration (m/s²)

Rearrange in terms of acceleration:

∑F/m = a

Plug in the given values:

44.5/52 = 0.856 m/s²

For the least amount of work, the exerting a force angle from horizontal is 76 degree.

Fcosθ−μN=maFcos⁡θ−μN=ma

N+Fsinθ−mg=0N+Fsin⁡θ−mg=0

(Unless Fsin>mgFsin>mg)

The angle is measured from the horizontal, and N is the upward normal force to the surface.

Work is defined as force times distance in the direction of motion... or a shift in energy. You want the man to do the work... guess: whole work. So attempt to accelerate the box (madmad) and against friction (NdNd).

So, how about this:

Minimizing force reduces effort for the same distance. As a result, we want the vertical component of force to be equal to and opposite to the weight. Any higher, and there is extra work propelling the box upwards.

This entirely removes friction, leaving only madness.

θ=sin−1[mg/F]

θ=sin−1⁡[mg/F]

Answer:The answer is circular orbits I hope this helps

Explanation:

The speed of Matt is 10 mph.

Doug runs 2 miles an hour faster than Matt, so let Matt’s speed equal x miles per hour. Then Doug’s speed equals x + 2 miles per hour. Each lap is one-quarter of a mile, so Doug runs 1.5 miles in the time it takes Matt to run 1.25 miles.

Rate of Matt is x

Rate of Dough is (x + 2)

Time taken by Matt is 1.25/x

Time taken by Dough is 1.25/(x + 2)

Distance covered by Matt is 1.25

Distance covered by Dough is 1.5

Dough and  Matt  took the same amount of time from the time Doug started, so make an equation by setting the two times in the chart equal to each other, and then solve for x:

            \(\frac{1.5}{(x + 2)}\) = \(\frac{1.25}{x}\)

              1.5x = 1.25(x + 2)

              1.5x = 1.25x + 2.5

           0.25x = 2.5

                   x = 10

So Matt ran at 10 miles per hour.
