Answer:
When adding more force to it.
Explanation:
First, we assume this as an ideal gas so we use the equation PV=nRT. Then, we use the conditions at STP that would be 1 atm and 273.15 K. We calculate as follows:
PV= nRT
PV= mRT/MM
1 atm (.245 L) =1.30(0.08206)(273.15) / MM
MM = 118.94 g/mol <--- ANSWER
A. 1/9
Explanation:
The gravitational force between two objects is given by
where
G is the gravitational constant
m1 and m2 are the two masses
r is the distance between the two masses
From the formula, we see that the magnitude of the force is inversely proportional to the square of the distance: therefore, if the distance is tripled (increased by a factor 3), the magnitude of the force changes by a factor
Answer:
50 arcsec.
Explanation:
Diameter of the Jupiter is 139822 km.
Minimum distance of the Jupiter from the earth is,
Now angular diameter of the Jupiter from the Earth can be calculate as,
Here, D is the diameter, and S is the minimum distance from the observing planet.
Now,
We know that,
Therefore,
Therefore, the angular diameter of planet Jupiter is 49.07 arcsec which is quite close to the 50 arcsec which is given in options.
