If Anya decides to make the star twice as massive, and not change the length of any crossbar or the location of any object, what

does she have to do with the mass of the smiley face to keep the mobile in perfect balance? Note that she may have to change masses of other objects to keep the entire structure balanced

13–82. the 8-kg sack slides down the smooth ramp. if it has a speed of 1.5 m> s when y = 0.2 m, determine the normal reaction
Softa [3030]
The second question necessitates a figure to provide an answer. For the initial question
The acceleration of the sack is
1.5² - 0² = 2a(0.2)
a = 5.63 m/s²
The ramp's reaction force is
F = 8 kg (5.63 m/s²)
F = 45 N
Differentiate the kinematic equation with respect to time to find the velocity's rate of increase.

Softa [3030]

Esta pregunta está incompleta, la pregunta completa es;

La figura muestra un recipiente sellado en la parte superior por un pistón móvil. Dentro del recipiente hay un gas ideal a 1.00 atm. 20.0°C y 1.00 L.

"¿Cuál será la presión dentro del recipiente si el pistón se mueve hasta la marca de 1.60 L mientras se mantiene constante la temperatura del gas?"

Answer:

la presión dentro del recipiente será 0.625 atm si el pistón se mueve hasta la marca de 1.60 L manteniendo constante la temperatura del gas

Explicación:

Dado que;

P₁ = 1.00 atm

P₂ =?

V₁ = 1 L

V₂ = 1.60 L

la temperatura del gas se mantiene constante

sabemos que;

P₁V₁ = P₂V₂

por lo que hacemos la sustitución

1 × 1 = P₂ × 1.60

P₂ = 1 / 1.60

P₂ = 0.625 atm

Por lo tanto, la presión dentro del recipiente será 0.625 atm si el pistón se mueve hasta la marca de 1.60 L mientras la temperatura del gas se mantiene constante

We have two equal size boxes, A and B. Each box contains gas that behaves as an ideal gas. We insert a thermometer into each box
Yuliya22 [3333]

Response:

d) In container A, the average kinetic energy per molecule exceeds that of container B.

e) Molecules in A exhibit a higher speed than those in B.

Reasoning:

Both containers are of identical size.

This indicates that the volume of each container is equal to V.

Temperature in container A is 50°C, which equals 323 K.

Temperature in container B is 10°C, equating to 283 K.

According to the ideal gas law:

P V = m R T

The quantities of gas mass are unspecified, making it impossible to determine which has a higher temperature or a greater number of molecules.

However, it is known that the average kinetic energy is directly related to the absolute temperature of a gas; thus, the kinetic energy in container A is greater due to its higher temperature. A higher kinetic energy implies increased molecular velocity.

Consequently, options d and e are accurate.

d) In container A, the average kinetic energy per molecule exceeds that of container B.

e) Molecules in A exhibit a higher speed than those in B.
