Answer:

he formula for the gravitational force includes the gravitational constant, which has a value . The unit of the gravitational force is Newtons (N). Fg = gravitational force between two objects ( ) G = gravitational constant ( ) m1 = mass of the first object (kg)

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

$=(n_1-n_2)\times M$

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

$=25.272\times 10^3\ g$

$m=25.272\ kg$

Type the correct answer in the box. Round your answer to the nearest whole number. The mass of Venus is 4.87 × 1024 kilograms, a

The gravitational effect on other bodies determines the weight (or the mass) of a planet. We must somehow measure the strength of its "tug" on another object in order to use gravity to find the mass of a planet. We can harness Newton's equations to deduce what the mass of the planet must be through observing the time it takes for the satellite to orbit its primary planet.

Given:

Mass of Venus = 4.87 x 1024 kg

= 4986.88

Mass of Jupiter = 1.898 x 1024 kg

= 1943.552

Mass of Jupiter compared to mass of Venus

1943.552 / 4986.88

= 0.3897330595482546

= 0.3897330595482546 x 100%

= 38.97%

So, in this problem, <span>the mass of Jupiter is about 0.39 times the mass of Venus.</span>
