1.) when the distance between the two objects is dubled then the gravitational Force btw them is <u>reduced by 4 times</u> I.e it becomes 1/4 of original due to the <u>inverse square law.</u>
2.) because the distance from the center of earth and pole is less then the distance btw pole and equator that's why due to <u>inverse square law</u> .
the gravitational Force on object at equator is less then the object on poles.
Answer:
The process of crystal forming is called crystallization. Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. In nature, crystals can form when liquid rock, called magma, cools.

Ummm It is given that,
Mass of bumper car, m₁ = 202 kg
Initial speed of the bumper car, u₁ = 8.5 m/s
Mass of the other car, m₂ = 355 kg
Initial velocity of the other car is 0 as it at rest, u₂ = 0
Final velocity of the other car after collision, v₂ = 5.8 m/s
Let p₁ is momentum of of 202 kg car, p₁ = m₁v₁
Using the conservation of linear momentum as :
p₁ = m₁v₁ = -342 kg-m/s
So, the momentum of the 202 kg car afterwards is 342 kg-m/s. Hence, this is the required solution.
