Answer:
9.64g/mL
Explanation:
Given parameters:
Mass of the metal = 106g
Volume of cylinder = 50mL
Volume difference = 31mL - 20mL = 11mL
Unknown:
Density of the metal = ?
Solution:
To find the density of the metal, we use;
Density =
Density = = 9.64g/mL
Answer: The gravitational pull on Moon B is greater than on Moon A because Moon B is closer to the new planet than Moon A.
Explanation:
The gravitational force exerted by the two objects on each other is inversely proportional to the square of the distance between the objects.
F = gravitational force or pull
G = gravitational constant on that planet
M = mass of the object-1
m = mass of object-2(Mass of Moon-A or Moon-B)
r = distance between two objects
With decease in distance 'r' the force between the object increases or vice versa.So, from this we can say that the gravitational pull on Moon-B is more than the gravitational pull on Moon-A because the Moon B is closer than the Moon-A from the new planet.
