1. En un diagrama PV trace las trayectorias para cada uno de los siguientes procesos que ocurren en forma sucesiva en un sistema

cerrado consistente en 2 moles de aire a condiciones estándar de presión y temperatura.
Proceso 1: isobárico hasta duplicar la temperatura inicial
Proceso 2: isotérmico hasta triplicar el volumen del estado inicial
Proceso 3: isocórico hasta reducir la temperatura al valor del estado inicial
Proceso 4: isotérmico hasta reducir el volumen al valor inicial.

Usando la ecuación PV = nRT 
n = 2
P = 101.3kPa / 1 atm 
T = 0 grados centígrados 
1. en el primer proceso hay un sistema isobárico y eso nos dice que la presión no cambia asi que la trayectoria va a ser una línea horizontal. 
2. en un proceso isotérmico la temperatura no cambia asi que la trayectoria va a ser una función exponencial. Aquí el volumen aumenta así que la función va a empezar de el lado izquierdo a el derecho.  
3. en un isocórico el volumen no cambia entonces la trayectoria es una linea vertical 
4. la trayectoria se ve igual que la del proceso 2 pero va de derecha a izquierda.

The final velocity of the ice is 82.0 m/s

Explanation:

The chuck of ice in this problem is in free fall, so we can use the following suvat equation for uniformly accelerated motion:

v^2-u^2=2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

In this problem, we have:

u = 0 is the initial velocity of the chuck of ice

a=g=9.8 m/s^2 is the acceleration of gravity (we choose downward as positive direction)

s = 343 m is the vertical displacement (the height of the tower)

Solving for v, we find the final velocity of the object:

v=\sqrt{u^2+2as}=\sqrt{0+2(9.8)(343)}=82.0 m/s

What is the action force of a bug hitting a windshield?
nalin [4]

Answer:

In the interaction between the bus and the bug, we can call the force "bus pushes bug" the action force. Then the force "bug pushes bus" is the reaction force. Since these forces are a Newton's Third Law action/reaction force pair, they are exactly the same size.

Explain why blocks with the same mass do not have the same density.
Pani-rosa [81]

Answer:

Density is equal to m/v where m is mass and v is volume. Even though the blocks have the same mass, they may have different volumes and therefore they will not have the same density.

An ideal heat engine absorbs heat at 100°C and exhausts heat at 0°C. What is its percent efficiency?
vampirchik [111]

Answer:

26.8 %

Explanation:

TH = 100°C = 100 + 273 = 373 K

Tc = 0°C = 273 K

The efficiency of the heat engine is given by

\eta = 1-\frac{T_{c}}{T_{H}}

\eta = 1-\frac{273}{373}

η = 0.268

η = 26.8 %

Thus, the efficiency of the heat engine is 26.8 %.
