Answer:
D. the masses of the objects and the distance between them
Explanation:
Gravitation is a force, a force doesn't care about the shape or density of objects, only about their masses... and distances.
And you can get it using the following equation:
Where :
G is the universal gravitational constant : G = 6.6726 x 10-11N-m2/kg2
m represent the mass of each of the two objects
d is the distance between the centers of the objects.
Answer:
4x
Explanation:
Use to do the question.
For first instance,
-------------------( 1 )
for second instance,
-----------------( 2 )
So by (1) and (2),
s = 4x
Complete question:
A 5-m³ container is filled with 900 kg of granite (density of 2400 kg/m3). The rest of the volume is air, with density equal to 1.15 kg/m³. Find the mass of air and the overall (average) specific volume.
Answer:
The mass of the air is 5.32 kg
The specific volume is 5.52 x 10⁻³ m³/kg
Explanation:
Given;
total volume of the container, = 5 m³
mass of granite, = 900 kg
density of granite, = 2,400 kg/m³
density of air, = 1.15 kg/m³
The volume of the granite is calculated as;
The volume of air is calculated as;
The mass of the air is calculated as;
The specific volume is calculated as;
