To solve this problem we need to use the proportional relationships between density, mass and volume, together with Newton's second law.
The force can be described as
Where,
m = Mass
g = Gravitational acceleration
At the same time the Density can be defined as
Where,
m = mass
V = Volume
Replacing the value of the mass at the equation of Force we have,
Since the difference between the two forces gives us the total Force then we have to
Where
Force of the water
= Force of plastic
Therefore with the values for this force we have,
Therefore the tension in the thread is 16.412N
Answer:
Explanation:
Given
magnitude of vector=8.7 m/s
Direction
Therefore vector x component is
=-2.104
i.e. it is acting in negative x axis
vector y component
Therefore it lies in negative y axis
Judging vector x and y component
It lies in third quadrant
