Explanation:
CAUSAS:
-El gobierno de chile ha destinado el 2% de sus recursos de salud pública para tratar los problemas de salud mental,lo cual es insuficiente debido a la alta demanda de pacientes que requieren atención especializada. Según la OMS (organización mundial de la salud) , cada gobierno debería destinar al menos el 5% de sus recursos para tratar este tipo de patologías o enfermedades mentales como la depresión,la ansiedad u otros trastornos bipolares
- El personal capacitado para tratar este tipo de enfermedades es muy escaso.
- Muchos de los chilenos que padecen este tipo de enfermedades no buscan ayuda inmediata, algunos recurren al alcohol o a los vicios como el cigarrillo o la marihuana , pensando que lograrán calmar la ansiedad o sus preocupaciones pero en realidad sucede lo contrario, aumentan la depresión y la ansiedad.
-Los problemas sociales, la crisis económica y el aumento de la pobreza así como el limitado acceso que tiene la población pobre chilena a un buen sistema de salud integrado,genera un significativo aumento de problemas de salud mental en especial en la población pobre o más desfavorecida del país.
CONSECUENCIAS:
Debido a los problemas de salud mental las incapacidades laborales han aumentado, afectando la economía del país.
Debido a la falta de tratamiento ,el suicidio y otras enfermedades como la esquizofrenia han aumentado. De igual manera la violencia intrafamiliar se ha incrementado e inclusive hasta los niños están empezando a sufrir este tipo de trastornos o enfermedades mentales,lo cual está afectando su desempeño escolar.
A cannon and a supply of cannonballs are in a sealed system railroad car. The car has a length of 20 meters, and a mass of 2000kg. The cannon fires to the right, the car recoils to the left. Fired cannonballs remain in the car after hitting the wall and land on the floor at the end of the car. The cannonballs have a mass of 15 kg each, and there are ten of them. (neglect mass of cannon) How far will the car move after all ten have been fired
Answer:
The distance the car moves after all ten cannonballs have been fired is 1.5 meters
Explanation:
The parameters given in the question are;
The length of the car = 20 meters
The mass of the of the cannon ball, m₁ = 2,000 kg
The direction the cannon fires = The right
The direction the car recoils = The left
The mass of each cannonball, m₂ = 15 kg
The number of cannonballs = 10
Let v₁ represent the speed of the car and let v₂ represent the speed of the cannonball, where momentum is conserved, we have;
m₁·v₁ = m₂·v₂
2000 × v₁ = 15 × v₂
400·v₁ = 3·v₂
Therefore, when the cannon ball travels 400 meters, the railroad car travels 3 meters
Similarly, when the cannon ball travels 400/20 = 20 meters, the distance the railroad car travels, d = 3/20 meters
We not that the railroad car and the car are brought to a stop each time the cannonball hits the watt
Therefore, the total distance moved by the car after all ten have been fired, [tex]d_{total}[/tex], is given as follows;
[tex]d_{total}[/tex] = d × The number of balls fired
∴ [tex]d_{total}[/tex] = 3/20 meters per ball × 10 balls = 3/2 meters = 1.5 meters
The total distance moved by the car, [tex]d_{total}[/tex] = How far the car moves after all ten have been fired = 1.5 meters.
A machine used 20 J of energy to make a
bicycle start. However, 6 J of energy was
wasted as heat. What is the percentage
efficiency of the machine?
a 30%
b 75%
C 70%
d 60%
Answer:
a. 30%
Explanation:
Given the following data;
Energy as effort, Ee = 20 J
Energy as heat, Eh = 6 J
To find the percentage efficiency (P.E);
P.E = Eh/Ee * 100
Substituting into the formula, we have;
P.E = 6/20 * 100
P.E = 6 * 5
P.E = 30 %
Therefore, the percentage efficiency of the machine is 30 %.

the boat. No one holds on to the boat. It begins to move away from the dock. Jen's legs
split wider and wider. Which law applies?
you tend to push off with the foot still on the boat.
Newtons 3rd law of motion hold that every action has an equal and opposite reaction.
So, the amount of force you use on your back foot to push yourself onto the dock, has an equal end opposite amount of force going the other way from your sole of your foot, which pushes the boat the other way.
The same principle applies when you fire a cannon - in the pirate films, you see the body of the cannon forced back as it is fired.

En una feria, se gana una jirafa de peluche lanzando una moneda a un platito, el cual está sobre una repisa más arriba del punto en que la moneda sale de la mano y a una distancia horizontal de 2.1 m desde ese punto (figura 3.41). Si lanza la moneda con velocidad de 6.4 m>s, a un ángulo de 60° sobre la horizontal, la moneda caerá en el platito. Ignore la resistencia del aire. A) ¿A qué altura está la repisa sobre el punto donde se lanza la moneda? B) ¿Qué componente vertical tiene la velocidad de la moneda justo antes de caer en el platito?
Answer:
A) La altura de la repisa sobre el punto donde se lanza la moneda es de aproximadamente 0,42 m
B) La velocidad de la moneda justo antes de que golpee el platillo es de aproximadamente 0,895 m/s hacia abajo
Explanation:
A) Los parámetros dados son;
La distancia horizontal del plato desde donde se lanza la moneda = 2,1 m
La velocidad con la que se lanza la moneda, u = 6,4 m / s
El ángulo al que se lanza la moneda, θ = 60 °
La componente horizontal de la velocidad, vₓ = 6.4 m / s × cos (60°) = 3.2 m/s
El tiempo que tarda la moneda en recorrer una distancia horizontal de 2,1 m, 't' se calcula de la siguiente manera;
t = 2,1 m/(3,2 m/s) = 0,65625 segundos
Por tanto, la altura de la moneda a 0,65625 segundos se da de la siguiente manera;
y = u × sin (θ) × t - (1/2) × g × t²
En t = 0,65625 segundos, obtenemos;
y = 6,4 × sin (60°) × 0,65625 - (1/2) × 9,81 × (0,65625) = 0,41840044589
La altura de la repisa sobre el punto donde se lanza la moneda, y ≈ 0.42 m
B) La velocidad vertical de la moneda justo antes de que golpee el platillo, [tex]v_y[/tex], se da como sigue;
[tex]v_y[/tex] = u × sin(θ) - g·t
∴ [tex]v_y[/tex] = 6.4 × sin(60°) - 9.81 × 0.65625 ≈ -0.895
La velocidad de la moneda justo antes de golpear el platillo, [tex]v_y[/tex] ≈ 0.895 m/s (hacia abajo)

please explain application of Stephan boltzmann law
Answer:
This law is used to find the luminosity (the rate of energy released), for an object given its surface temperature. This law assumes the body acts as a black-body radiator (an object that emits energy from the entire EM spectrum)
For a given object with a constant surface area, the Stefan-Boltzmann law says that luminosity is proportional to the temperature raised to the fourth power.

Answer:
They both involve wave interactions.
Explanation:
Diffraction is defined as the bending of waves around obstacles. Refraction can be defined as the bending of the light when it transfers from one substance to another. The main similarity between the diffraction and refraction is that both involves the interaction of the waves with the substance and also causes the waves to bend and change their direction. Hence, they both involve wave interaction is the correct option.
What diffraction and refraction have in common is that they both involve wave interactions. This is further explained below.

A rigid body of moment of inertia 0.5 kg.M^2 rotates with 2 RPM. How much torque is needed to increase the rotation to 10 RPM in 5 seconds.
Answer:
T = 0.084 Nm
Explanation:
First, we will calculate the angular acceleration:
[tex]\alpha = \frac{\omega_f - \omega_i}{t}[/tex]
where,
α = angular acceleration = ?
ωf = final angular speed = (10 RPM)(2π rad/1 rev)(1 min/60 s) = 1.05 rad/s
ωi = initial angular speed = (2 RPM)(2π rad/1 rev)(1 min/60 s) = 0.21 rad/s
t = time = 5 s
Therefore,
[tex]\alpha = \frac{1.05\rad/s - 0.21\ rad/s}{5\ s}\\\\\alpha = 0.168\ rad/s^2[/tex]
Now, for the torque:
[tex]T = I\alpha[/tex]
where,
T = torque = ?
I = moment of inertia = 0.5 kg.m²
Therefore,
[tex]T = (0.5\ kg.m^2)(0.168\ rad/s^2)\\[/tex]
T = 0.084 Nm
