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

If you are in a spaceship that is sitting on the surface of a planet, you feel your weight. How does this compare to the weight
nordsb [41]

Answer:

You will feel more weight if it is accelerating out of the planet.

You will feel less weight if it is accelerating towards the planet.

Explanation:

The weight that you are observing or feeling is basically due to the change in acceleration of your fall or rising up in the spaceship. When the acceleration is stationary on the surface, you experience your normal weight due to the gravitational acceleration of that planet.

When the spaceship accelerates above or out of the planet you experience acceleration more than the acceleration of gravity hence more weight.

When the spaceship accelerates towards the planet you experience acceleration less than the acceleration of gravity hence less weight.

If the spaceship is free falling at the gravitational acceleration you experience a zero weight

If the labor force of 155 million people is growing by 1.0 percent per year, how many new jobs have to be created each month to
dybincka [34]

First let us compute for the total growth in population.

Growth = 155 million * 0.01

Growth = 1.55 million

 

Since there are 12 months in a year, therefore the new jobs every month should be:

new jobs per month = 1.55 million / 12

<span>new jobs per month = 0.129 million = 129,167 </span>
