(6) Given that,
Force in east direction = 67 N
Force in west direction = 82 N
Solution,
According to the given figure,
Two forces are acting in opposite direction. Maximum force is acting in west direction. It means the net force is acting in west direction.
Net force = 82-67
= 15 N (Due west)
The forces are unbalanced. It is because the magnitude of force in west is more than in east.
Net force = 15 N, Direction of motion = West and the forces are unbalanced.
Answer:
a) Total mass form, density and axis of rotation location are True
b) I = m r²
Explanation:
a) The moment of inertia is the inertia of the rotational movement is defined as
I = ∫ r² dm
Where r is the distance from the pivot point and m the difference in body mass
In general, mass is expressed through density
ρ = m / V
dm = ρ dV
From these two equations we can see that the moment of inertia depends on mass, density and distance
Let's examine the statements, the moment of inertia depends on
- Linear speed False
- Acceleration angular False
- Total mass form True
- density True
- axis of rotation location True
b) we calculate the moment of inertia of a particle
For a particle the mass is at a point whereby the integral is immediate, where the moment of inertia is
I = m r²
Answer:
Atomic name is your answer.
