Assume that the pressure in a room remains constant at 1.01

Ray Of Light [21]

Answer:

Explanation:

Given

Pressure $P_1=1.01\times 10^5 Pa$

Volume of air $V=60 m^3$

Initial Temperature $T_1=289 K$

$T_2=302 K$

Initial moles is given by

$PV=nRT$

$n_1=\frac{P_1V_1}{RT_1}$

$n_1=\frac{1.01\times 10^5\times 60}{R\cdot 289}$

when some gas escape out

no of moles is equal to

$n_2=\frac{P_2\times V_2}{R\cdot T_2}$

$n_2=\frac{1.01\times 10^5\times 60}{R\cdot 302}$

remaining no of moles $=n_1-n_2$

$=\frac{1.01\times 10^5\times 60}{R\cdot 289}-\frac{1.01\times 10^5\times 60}{R\cdot 302}$

$=\frac{1.01\times 10^5\times 60}{R}(\frac{1}{289}-\frac{1}{302})$

Mass of air escape out

$=(n_1-n_2)\times M$

$=(\frac{1.01\times 10^5\times 60}{R}(\frac{1}{289}-\frac{1}{302}))\times 28$

$=25.272\times 10^3\ g$

$m=25.272\ kg$

Does the rankine degree represent a larger or smaller temperature unit than the kelvin degree

zvonat [6]

The best and most correct answer among the choices provided by the question is the first choice, larger.

Rankine is Fahrenheit + 460 , while Kelvin is Celsius + 273. We all know that Fahrenheit has larger number compared to kelvin , thus rankine is much larger.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

ECONOMICS !!!!

gulaghasi [49]

Answer:

Explanation:

Absolute advantage is the capability of a commercial entity to produce goods using fewer resources compared to rivals. Using the same inputs, an entity with an absolute advantage produces a larger output compared to competitors. It means the firm has a lower marginal cost of production. Therefore, its products will have the lowest prices in the market.

(a) a fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerte

Musya8 [376]

The dimension of force, F is ML/T².

<h3>What is force?</h3>

Force is a push o push agent which causes a change in the state of rest or motion of an object.

From a fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass.

Mathematically; acceleration ∝ F/m

F = ma

dimension of Mass = M

dimension of acceleration = L/T²

dimension of force, F = ML/T²

In conclusion, the dimension of force is obtained from the dimensions of mass and acceleration.

A 600kg car is at rest , and then accelerates to 5n/s what is the original kinetic energy?

lubasha [3.4K]

M = 600 kg
u = 0 (as the car was at rest initially)
v = 5 m/s
Initial kinetic energy = ½mu²
= ½×600×0
= 0
Final kinetic energy = ½mv²
= ½×600×25
= 7500 J
