Answer:
L= 1.468 m
Explanation:
The moment of inertia of the rod about its center is (1/12)m_RL^2
The moment of inertia of each of the two bodies about the described axes is m_B(L/2)2
Hence, the moment of inertia of three body system is (1/12)m_RL^2+ 2×m_B(L/2)^2 which is given to be equal to I_T
=> L^2[(1/12)m_R+m_B/2] = I_T
=> L2 = IT/(mR/12+ mB/2)
=> L = sqrt( 12I_T/(m_R+6m_B))
now putting the value of m_R= 3.47 kg
m_B= 0.263 kg
I_T = 0.97 kg/m^2
L= 1.468 m is the length of the rod be so that the moment of inertia of the three-body system
Answer:
The area of the gold foil is
Explanation:
Mass of gold foil , m= 27.63 g
Thickness of gold foil ,
Density of gold ,
Let the area of gold foil be A then the total volume of gold foil is given by
=>
=>
Thus the area of the gold foil is
Answer:
Explanation:
As we know that initial angular speed of the tub was zero and then it increases uniformly to 4 rev/s in t = 6.00 s
so we will have
Now when the tub will comes to rest uniformly after opening the lid in time interval of t = 15 s
then we have
Now total angular displacement of the tub is given as
so number of revolutions is given as
