The angular momentum of a rotation object is the product of its moment of inertia and its angular velocity:
L = Iω
L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
Apply the conservation of angular momentum. The total angular momentum before disks A and B are joined is:
L_{before} = (3.3)(6.6) + B(-9.3)
L_{before} = -9.3B+21.78
where B is the moment of inertia of disk B.
The total angular momentum after the disks are joined is:
L_{after} = (3.3+B)(-2.1)
L_{after} = -2.1B-6.93
L_{before} = L_{after}
-9.3B + 21.78 = -2.1B - 6.93
B = 4.0kg·m²
The moment of inertia of disk B is 4.0kg·m²
Plants produce food for themselves so they begin the food chain
Explanation :
In Interspecific competition, different individuals of different species fight for the same resource in an ecosystem. The resources can be food or living space.
Birds belong to the group of<em> aves</em>, squirrels and chipmunks are from the family of <em>Sciuridae</em>.
All three are from different species. They are on the same ecosystem i.e. tree. They form the interspecific competitions.
Answer:
s = 50.4 m
Hence, the point C is 50.4 m towards east from point B
Explanation:
Since, the motorcyclist travels at a constant speed in straight line towards east after point B. Therefore, we can use the following equation in this case:
s = vt
where,
s = distance covered = position of point C = ?
v = uniform speed of motorcyclist = 18 m/s
t = time interval = 2.8 s
Therefore,
s = (18 m/s)(2.8 s)
<u>s = 50.4 m</u>
<u>Hence, the point C is 50.4 m towards east from point B</u>
