state the following, 1.the principal of moment, 2.the principal of flotation, 3.Archimedes principle

1.

Explanation:

1.The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point.

2.When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation” where a floating object displaces a weight of fluid equal to its own weight.

3.a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.

it should be -8.6 cm hope this out
