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

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.

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

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.

Explanation:

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

Answer:

kinetic energy

Explanation:

vinegar and baking soda are composed of atoms which react to each other when mixed therefore they convert the potential energy inti kinetic energy.

Answer:

Amontons's law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas

Answer:

The gravity is pulling the diver downwards but the rotation of the body means gravity cant pull him down as quickly

Explanation:

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.

Answer:

I think it is C

Explanation:

If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.

Answer:

the force that the car’s tires exerted on the road is 2,666.67 N.

Explanation:

Given;

mass of the car, m = 1,200 kg

initial velocity of the car, u = 0

final velocity of the car, v =  10.0 m/s

time of motion, t = 4.50 s

The force the car’s tires exerted on the road is calculated as follows;

[tex]F = ma= \frac{m(v-u)}{t} \\\\F = \frac{1200(10-0)}{4.5} \\\\F = 2,666.67 \ N[/tex]

Therefore, the force that the car’s tires exerted on the road is 2,666.67 N.

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

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.

Explanation:

velocity = wavelength × frequency => v= f1 × λ => f1 = v/ λ

λ = stays the same

v = doubles

2v = f2 × λ

2v/λ = f2

now ,

f2/f1= 2vλ/ vλ = 2

f2 = 2f1

therefore frequency is doubled
