Explanation:
From the question we are told that
The initial angular velocity of the spinning top is
The angular velocity after it slow down is
The time for it to slow down is
The rotational inertia due to friction is
Generally the change in the angular momentum is mathematically represented as
substituting values
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity ( )
- For 1 newton force,
F= m* 9.8
or, m= = 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
