A 5kg object is moving downward at a speed of 12m/s. If it is currently 2.6m above the ground, what is its kinetic energy?
Answer:
360J
Explanation:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
Cuales podrian ser las causas y consecuencias del aumento de problemas de salud mental en la población chilena
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.

If the battery has a voltage of 24 Volts, Find the current when switch is closed.
Answer:
6amps
Explanation:
The question is not complete
Given data
voltage= 24volts
Say we have a resistance of 4 ohms
We can then find the current using the formula
V= IR
substitute
24= I*4
I= 24/4
I= 6 amps
Hence the current when the voltage is 24volt and a resistance of 4 ohms is
6amps
According to Newton’s second law, the mass of an object is 120kg and it is accelerating at a rate of 5m/s2 . The object’s force would be
Answer:
F = 600 N
Explanation:
The second law is F = m * a
The mass (m) is in kg = 120
The acceleration in in m/s^2 = 5
The force is in Newtons.
m and a do not require any conversions. They are in the correct units.
F = 120 * 5
F = 600 N

Consider 2 steel rods, A and B, B has three times the area and twice the length of A, so young modulus of B will be what factor times young modulus of A?
Answer:
[tex]\frac{Y}{Y_o}[/tex] = 2/3
Explanation:
The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain
Y = [tex]\frac{ \frac{F}{A} }{\frac{\Delta L}{L_o} }[/tex]
let's use the subscript "o" for rod A
I = [tex]\frac{ \frac{F}{A_o} }{ \frac{\Delta L}{L_o} }[/tex]
tells us that rod B has
A = 3 A₀
L = 2 L₀
we substitute
Y = [tex]\frac{ \frac{F}{A} }{ \frac{\Delta L}{L} }[/tex]
Y = [tex]\frac{ \frac{F}{3A_o} }{ \frac{\Delta L}{ 2L_o} }[/tex]
y = ⅔ [tex]\frac{ \frac{F}{A_o}}{ \frac{\Delta }{L_o} }[/tex]
substituting the value of Y₀
Y = ⅔ Y₀
[tex]\frac{Y}{Y_o}[/tex] = 2/3

While traveling along a highway a driver slows from 31 m/s to 15 m/s in 8 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down or deceleration.)
Answer:
The automobile's acceleration in that time interval is -2 m/s^2
Explanation:
The acceleration is defined as the rate of change of the velocity.
The average acceleration in a given lapse of time is calculated as:
A = (final velocity - initial velocity)/time.
In this case, we have:
initial velocity = 31 m/s
final velocity = 15 m/s
time = 8 seconds.
Then the average acceleration is:
A = (15m/s - 31m/s)/8s = -2 m/s^2
any tips for an ollie ?
Answer:
skateboard mid-ollie is being actively steered. This is exactly what makes doing an ollie so hard. It's not enough to get the skateboard up into the air - you also have to steer it while it's in the air. You should keep your hands up in the hair a bit to help with balance, scrunch your legs a bit down to have a proper and effective jump. wear nee pads incase you dont fix the landing. Practice jumping on ur skate board tho, if u jump at it without knowing much youll just get hurt.

What is the temperature increase of 4.0 kg of water when it is heated by an 8.0 ^102 W immersion heater for exactly 10.0 min? (cp = 4186 J/kg·°C)
Answer:
ΔT = 28.667°C is the answer.
Explanation:
Given,
Mass of water = 4.0 kg
Water is heated by = 8 × 10² W = 800 W
Time = 10 min = 10 × 60 = 600 s
Now,
using the equation of specific heat,
Q = mcΔT
where c is the specific heat capacity of water = 4186 J/kg°C
Q = Pt
Substituting,
Pt = mcΔT
800 × 600 = 4 × 4186 × ΔT
480000 = 16744 × ΔT
ΔT = 28.667
∴Temperature increased, ΔT = 28.667°C
Which one of the following statements is true: The reactive power is the power dissipated in the form of heat by the network. The reactive power is the power delivered to a load without considering the effects of the power-factor angle of the load. The apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load. The real power is the power associated with reactive elements that provides a measure of the energy associated with setting up the magnetic and electric fields.
Answer:
The apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load
Explanation:
If I and V are the current and voltage across the load, the apparent power, = IV
Since,
apparent power = active power + reactive power
active power = IVcosФ
reactive power = IVsinФ
So, IV = IVcosФ + IVsinФ
where I = current, V = voltage and Ф = power factor angle.
We see that the apparent power is the product of the current, I and the Voltage, V without considering the power factor angle of the load.
So, the apparent power is the power delivered to a load without considering the effects of the power-factor angle of the load.

Calcula la cantidad de calor que hay que darle a 0,01 l de mercurio para que su temperatura pase de 10 ºC a 25 ºC. Datos: rho=13,6 g/cm3 ; Ar(Hg)=200,6; C=28,1 J/(mol∙K).
Respuesta:
286 J
Explicación:
Paso 1: Convertir 0,01 L de Hg a cm³
Usaremos los siguientes factores de conversion.
1 L = 1000 mL
1 mL = 1 cm³
0,01 L × 1000 mL/1 L × 1 cm³/1 mL = 10 cm³
Paso 2: Calcular la masa (m) correspondiente a 10 cm³ de Hg
La densidad de Hg es 13,6 g/cm³.
10 cm³ × 13,6 g/cm³ = 136 g
Paso 3: Calcular los moles(n) correspondientes a 136 g de Hg
La masa molar de Hg es 200,6 g/mol.
136 g × 1 mol/200,6 g = 0,678 mol
Paso 4: Calcular la cantidad de calor requerido (Q)
Usaremos la siguiente fórmula.
Q = c × n × (T₂ - T₁)
donde,
c: calor específico del Hg (28,1 J/mol.K = 28,1 J/mol.K)
T₂ y T₁: temperaturas final e inicial, respectivamente
Q = (28,1 J/mol.°C) × 0,678 mol × (25°C - 10 °C) = 286 J
