A una temperatura de 329°K una placa de aluminio tiene un área de 15 m2, si su temperatura disminuye hasta 288°K; ¿Cuál es el valor de su área final?

Answers

Answer:

El área final de la placa de aluminio es 14.971 metros cuadrados.

Explanation:

Para pequeñas deformaciones, la expresión para la dilatación de área es la siguiente:

[tex]A_{f} = A_{o} \cdot [1+2\cdot \alpha \cdot (T_{f}-T_{o})][/tex] (1)

Donde:

[tex]A_{o}[/tex], [tex]A_{f}[/tex] - Áreas inicial y final de la placa, medidas en metros cuadrados.

[tex]\alpha[/tex] - Coeficiente de expansión lineal, medido en [tex]\frac{1}{K}[/tex].

[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Temperaturas inicial y final de la placa, medidas en Kelvin.

Si sabemos que [tex]A_{o} = 15\,m^{2}[/tex], [tex]\alpha = 23\times 10^{-6}\,\frac{1}{K}[/tex], [tex]T_{o} = 329\,K[/tex] y [tex]T_{f} = 288\,K[/tex], entonces el área final de la placa es:

[tex]A_{f} = (15\,m^{2})\cdot \left[1+2\cdot \left(23\times 10^{-6}\,\frac{1}{K} \right)\cdot (288\,K-329\,K)\right][/tex]

[tex]A_{f} = 14.971\,m^{2}[/tex]

El área final de la placa de aluminio es 14.971 metros cuadrados.

The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.

A. The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.

B. The gravitational potential energy decreases and the kinetic energy increases.As soon as the ball starts moving it no longer has gravitational potential energy; it has only kinetic energy.

C. The kinetic energy and and gravitational potential energy both decrease. Both forms of energy are used up as the ball moves and are not transformed into any other form of energy.

D. The gravitational potential energy and the kinetic energy both stay the same. One form of energy cannot be transformed into a different form of energy.

From the question given above, the following data were obtained:

Power input = 600 MW

Power output = 540 MW

I. Determination of the efficiency.

Power input = 600 MW

Power output = 540 MW

Efficiency =?

Efficiency = output / input × 100

Efficiency = 540 / 600 × 100

Efficiency = 90%

II. Determination of the power wasted by the pump.

Power input = 600 MW

Power output = 540 MW

Power wasted =?

Power wasted = Power input – Power output

Power wasted = 600 – 540

Power wasted = 60 MW

A 50 kg bumper car with a 40 kg child and it is at rest when a 60 kg child in her own bumper car slams into it the collision last point1 seconds and the rubber bumpers are perfectly bouncy with no heating from the collision what is the force experienced by the first car

Answers

Answer:

F = 99 v₂₀

v₂₀ = 1 m / s, F = 99 N

Explanation:

In this exercise it is asked to find the force during the collision, for this we use the relationship between the momentum and the momentum of car 1

I = Δp

F t = p_f- p₀

F t = m (v_f -v₀) (1)

We must find the final speed of car 1, for this we define a system formed by the two cars, in this case the forces during the collision are internal and the moment is conserved

initial instant. Before the crash

p₀ = 0 + m₂ v₂₀

final instant. After the crash

p_f = m₁ v₁ + m₂ v_{2f}

the moment is preserved

p₀ = p_f

m₂ v₂₀ = m₁ v_{1f} + m₂ v_{2f} (2)

m₂ (v₂₀ - v_2f}) = m₁ v_{1f}

as the collision is elastic the kinetic energy is also conserved

K₀ = K_f

½ m₂ v₂₀² = ½ m₁ v_{1f}² + ½ m₂ v_{2f}²

m₂ (v₂₀² -v_{2f}²) = m₁ v_{1f}²

let's write our system of equations, using

a² - b² = (a + b) (a-b)

m₂ (v₂₀ - v_{2f}) = m₁ v_{1f}

m₂ (v₂₀ -v_{2f}) (v₂₀ + v_{2f}) = m₁ v_{1f}²

to solve we divide the equations

v₂₀ + v_{2f} = v_{1f}

with this we substitute in equation 2 and find the speed of each car, in this case we need the speed of car 1

m₂ v₂₀ = m₁ v_{1f} + m₂ (v_{1f}-v₂₀)

2m₂ v₂₀ = (m₁ + m₂) v_{1f}

v_{1f} = [tex]\frac{2m_2}{m_1+m_2} v_{2o}[/tex]

We substitute in the drive ratio of car 1

F t = m (v_f -v₀)

F = m₁ (\frac{2m_2}{m_1+m_2} v_{2o} - 0) / t

F = [tex]\frac{2m_1 m_2 }{m_1+m_2} \ \frac{v_{2o}}{t}[/tex]

the mass of each car is the mass of the car plus the mass of the boy

m₁ = 50 +40 = 90 kg

m₂ = 50 +60 = 110 kg

time is t = 1

we substitute the values

F = [tex]\frac{ 2\ 90 \ 110}{90+110} \ \frac{v_{2o}}{1}[/tex]2 90 100/90 + 110 vo2 / 1

F = 99 v₂₀

The value of the initial velocity of car 2 is not indicated in the problem, if this velocity is known it can be included and the force value is obtained, suppose that the initial velocity v₂₀ = 1 m / s

F = 99 N
