Deciliter = 1/10 of a liter
Milliliter = 1/1000 of a liter
So, there are 100 milliliters in one deciliter
Determined the displacement of a plane is 66 m:s
In vacuum and empty space, it's 299,792,458 meters per second
(186,282.4 miles per second).
In any material stuff, it's somewhat less. How much less depends on
what stuff it is ... it's different in each material "medium".
Answer:
The final angular velocity is
Explanation:
From the question we are told that
The mass of the first disk is m
The radius of the first disk is r
The mass of second disk is M
The radius of second disk is R
The speed of rotation is w
The moment of inertia of second disk is
Since the first disk is at rest initially
The initial angular momentum would be due to the second disk and this is mathematically represented as
Now when the first disk is then dropped the angular momentum of the whole system now becomes
This above is because the formula for moment of inertia is the same for every disk
According to the law conservation of angular momentum
=>
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
