Answer:
17.71 kgm²s⁻¹
Explanation:
<em>Angular momentum </em>is the rotational momentum , which is quite similar to linear momentum.main difference is that here we consider a rotational motion.
*The total angular momentum of a closed system remains constant.
by definition ,
angular momentum = moment of inertia (I) × angular velocity (ω)
where
<em>ω = 2π × frequency (f)</em> = 2π × 6
<em>angular momentum = 0.47 × 12π = 17.71 kgm²s⁻¹</em>
Answer:
A biased person favors one side or issue over another.
Explanation:
For example say there is a soccer game going on Blue Team VS Red Team,
and the ref wants the Blue Team to win, so he helps the Blue Team win the calling fouls for them or not calling foals for the Red Team.
He is being biased.
To solve this problem it is necessary to apply the equations related to the conservation of momentum.
This definition can be expressed as
Where
= Mass of each object
= Initial Velocity of each object
= Final velocity
Rearranging the equation to find the final velocity we have,
Our values are given as
Replacing we have,
Therefore the final velocity is 6.5m/s
Answer:
Explanation:
The gravitational force between two corpses is given by the following equation:
Where F is the force, G is the gravitational constant
(), M and m are the masses of the corpses and d is the distance between them.
So we have that:
