Answer:

Not sure what yours looking for but When a disease is widespread, epidemiological studies investigate what associated factors, such as location, swx, exposure to chemicals and many others, make a population more or less likely to have an illness, condition, or disease thus helping determine its etiology.

Answer:

Some anxiety disorders have different symptoms and it is important to figure out how those symptoms develop. Symptoms may develop from physiological, psychological, or environmental influences. Physiological factors may include heredity, chemical and hormonal imbalances, gender (females are more prone to anxiety than males), and anxiety sensitivity, which has to do with how one’s body reacts to chemical changes. Psychological influences focus on how one’s mind reacts to fearful situations. Environmental factors also influence how individuals deal with fearful situations.  Environmental stress levels, how we think or interpret situations, and our observations of how others react to similar situations all impact how we manage anxiety.

Convert 100°c into Faherenite and kelvin in steps.​

Answers

Answer:

100°c = 373.15 K

100°C=212°F

Explanation:

Given the 100°C

To convert Celsius to Kelvin, we need the following equation.

°C + 273.15 = K

100°C + 273.15 = K

373.15 = K

Therefore, 100°c = 373.15 K

Celsius To Fahrenhite:

F = 9/5C + 32

   =9/5(100)+32

  = (180) + 32

Why does a bowling ball and a feather hit the ground at the same time when they are dropped in a vacuum?

Answers

Answer:

See the explanation below.

Explanation:

This is because the vacuum chamber removes all the air contained and for this reason, there is no force that opposes the movement of the feather when falling. We must remember that the free fall equation of kinematics is not a function of the mass of an object.

[tex]v_{f} =v_{o} +g*t[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity [m/s]

g = gravity acceleration [m/s²]

t = time [s]

As we can see the mass of the object is not included in the equation.

Un auto se mueve con velocidad constante de 20 m/s y la mantiene durante 20 s. Después se le aplica una aceleración constante y aumenta su velocidad a 40 m/s, recorriendo durante el cambio de velocidad una distancia de 200 m ¿Cuál es el tiempo empleado en el recorrido total?

Answers

Answer:

26.67 s

Explanation:

v = Velocidad final = 40 m/s

u = Velocidad inicial = 20 m/s

[tex]t_1[/tex] = Tiempo inicial = 20 s

[tex]t_2[/tex] = Tiempo empleado durante la aceleración

a = Aceleración

s = Desplazamiento del automóvil durante la aceleración = 200 m

De las ecuaciones lineales de movimiento tenemos

[tex]v^2-u^2=2as\\\Rightarrow a=\dfrac{v^2-u^2}{2s}\\\Rightarrow a=\dfrac{40^2-20^2}{2\times 200}\\\Rightarrow a=3\ \text{m/s}^2[/tex]

[tex]v=u+at_2\\\Rightarrow t_2=\dfrac{v-u}{a}\\\Rightarrow t_2=\dfrac{40-20}{3}\\\Rightarrow t_2=6.67\ \text{s}[/tex]

El tiempo necesario para acelerar es 6.67 s

El tiempo total necesario para toda la ruta es [tex]t=t_1+t_2=20+6.67=26.67\ \text{s}[/tex].

Select one:
A. 100 kg at rest
B. 20 kg at 2 m/s
C. 5 kg at 50 m/s
D. 10 kg at 5 m/s​

Answers

Answer: C

Explanation:

A: 100kg*0m/s (obviously not answer)

B: 20kg*2m/s (=40)

C: 5kg*50m/s (=250, safe bet this one is it)

D: 10kg*5m/s (=50)

5 kg at 50 m/s, with a momentum of 250 kg m/s has the most momentum.

Hence, the correct option is C.

To calculate momentum, we use the formula:

Momentum (p) = Mass (m) × Velocity (v)

Let's calculate the momentum for each option:

A. 100 kg at rest

Momentum = 100 kg × 0 m/s = 0 kg m/s

B. 20 kg at 2 m/s

Momentum = 20 kg × 2 m/s = 40 kg m/s

C. 5 kg at 50 m/s

Momentum = 5 kg × 50 m/s = 250 kg m/s

D. 10 kg at 5 m/s

Momentum = 10 kg × 5 m/s = 50 kg m/s

Therefore, 5 kg at 50 m/s, with a momentum of 250 kg m/s has the most momentum.

Hence, the correct option is C.

Answers

Answer: nah

Explanation:

A wet lab experiment for Coulomb's law involves measuring the force between charged objects immersed in a liquid. The experiment is called a "wet" lab because it involves liquid or aqueous solutions.

What is Coulomb's law?

Coulomb's law is an equation that describes the electrostatic force between two charged particles.

It states that "the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."

The equation is given by:

F = k×(q₁ × q₂) / r²

Where

F = the electrostatic force,

k =Coulomb's constant,

q₁ and q₂= the charges of the particles,

r =the distance between the.

In this question,

In the experiment, two conductive objects are charged with opposite charges using a high-voltage power supply, which can be controlled to vary the magnitude of the charges.

The two objects are then immersed in a non-conductive liquid, such as oil or water, and positioned a fixed distance apart.

Using a force sensor or a balance, the force between the two objects is measured as they move toward each other. By measuring the force at different distances, the experiment can verify Coulomb's law, which predicts that the force between two charged objects is proportional to the product of their charges and inversely proportional to the square of their separation distance.

The experiment can be performed with different pairs of charged objects with different magnitudes of charge and separation distances, allowing the relationship between the force and these variables to be investigated. This provides insight into the electrostatic interaction between charged objects in a liquid, which has applications in various fields, including electrochemistry, material science, and biophysics.

Therefore, in a wet lab experiment on Coulomb's law, we have to immerse the apparatus in aqueous solutions.

A man drops a penny V=0 off the top of the Golden Gate Bridge how fast will the penny be moving when it hits the ground? The golden hat bridge is 275 meters tall

Answers

Answer:

Vf = 73.4 m/s

Explanation:

This is the case of vertical motion where we have to find the final velocity of the penny when it hits the ground. We can use 3rd equation of motion to find the final velocity:

2gh = Vf² - Vi²

where,

g = 9.8 m/s²

h = height = 275 m

Vf = Final Velocity = ?

Vi = Initial Velocity = 0 m/s

Therefore,

2(9.8 m/s²)(275 m) = Vf² - (0 m/s)²

Vf = √5390 m²/s²

Vf = 73.4 m/s

The speed with penny dropped from the Golden Gate Bridge hits the ground is 73.4m/s.

Given the data in the question;

Since the penny was at rest before it was dropped

Initial velocity; [tex]u = 0[/tex]Height or distance of the golden hat bridge; [tex]s = 275m[/tex]

Final velocity; [tex]v = \ ?[/tex]

To determine the speed with which the penny hits the ground, we use the Third Equation of Motion:

[tex]v^2 = u^2 + 2as[/tex]

Where v is the final velocity, u is the initial velocity, s is the height of the bridge and a is acceleration due to gravity ( since its under gravity; [tex]a = g = 9.8m/s^2[/tex] )

We substitute our values into the equation

[tex]v^2 = 0 + [ 2\ *\ 9.8m/s^2\ *\ 275m]\\\\v^2 = 5390m^2/s^2\\\\v = \sqrt{5390m^2/s^2}\\\\v = 73.4 m/s[/tex]

Therefore, the speed with penny dropped from the Golden Gate Bridge hits the ground is 73.4m/s.

Explanation:

A planet similar to the Earth has a radius 5 × 106 m and has an acceleration of gravity of 10 m/s 2 on the planet's surface. The planet rotates about its axis with a period of 25 h. Imagine that the rotational speed can be increased. If an object at the equator is to have zero apparent weight, what is the new period? Answer in units of h.

Answers

Answer:

The new period is approximately 3.93 × 10⁻⁷ h

Explanation:

The radius of the planet = 5 × 10⁶ m

The acceleration due to gravity on the planet, a = 10 m/s²

The period of the planet = 25 h

The centripetal force, [tex]F_c[/tex], is given by the following equation;

[tex]F_c = \dfrac{m \cdot v^2}{r}[/tex]

Where;

v = The linear speed

r = The radius

Therefore, for the apparent weight, W, of an object to be zero, we have;

The weight of the object = The centripetal force of the object

W = Mass, m × Acceleration due to gravity, a

∴ W = [tex]F_c[/tex]

Which gives;

[tex]m \times a = \dfrac{m \cdot v^2}{r}[/tex]

[tex]a = \dfrac{v^2}{r}[/tex]

∵ r = The radius of the planet

We have;

[tex]10 = \dfrac{v^2}{5 \times 10^6}[/tex]

v² = 10 × 5 × 10⁶

v = √(10 × 5 × 10⁶) ≈ 7071.07 m/s

The new frequency = Radius of the planet/(Linear speed component of rotation)

∴ The new frequency = 5 × 10⁶/(7071.07) = 707.107 revolutions per second

The new frequency = 707.107 × 60 × 60 = 2545585.2 revolutions per second

The new period = 1/Frequency ≈ 3.93 × 10⁻⁷ hour.

What is psychosocial development?

The term "psychosocial development" refers to how a human's personality changes during childhood and adulthood, as well as how social skills are acquired. The eight phases of psychosocial development were first described by psychologist Erik Erikson in the 1950s. According to Erikson, each stage is marked by a "psychosocial crisis" that can either have a good or negative impact on a person's personality.

Erikson asserts that a person's personality and social abilities change over the course of eight stages that span the entirety of their life. A person encounters a psychosocial crisis—critical issues—at each level, which must be overcome.

The way a person handles each of these crises has an impact on their personality. If people respond favorably, they acquire virtue (moral behavior).
