To develop this problem we will apply the Archimedes model. As well as the definitions of Weight based on mass and acceleration. The first in turn will be considered under the relationship of Density and Volume. From the values given we have to:
Since it is in equilibrium, the weight of the object will have a reaction from the water, which will cause the sum of forces between the two objects to be zero, therefore
The value of gravity is canceled because it is a constant
The portion of the object that is submerged corresponds to 82%, while the portion that is visible, above the water level will be 18%
Answer:
The Buoyant force is
Explanation:
From the question we are told that
The mass of the block is m = 2 kg
Generally the magnitude of the buoyant is equivalent to the weight of the block
Hence the buoyant force is
=>
=>
Answer:
Explanation:
Given
initial speed
coefficient of kinetic friction
It moves a distance d after that it comes to rest
acceleration offered by table top
Answer:
option 3
Explanation:
work is said to be the ability to move an object from it initial position. therefore, holding a tray is not a work
just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
