Answer:
The angular momentum of a cylinder, when it is rotating with constant angular velocity is Lini =Iωi
. When two cylinders are added to the rotating cylinder, which are identical in their dimensions, the moment of inertia of the entire system increases (since mass increases). The final moment of inertia will be 3I
Since friction exist, all the cylinders start rotating with same angular velocity, the new angular velocity can be calculated using conservation of angular momentum
Thus, Iωi =3Iωf ⟹ωf =ωi/3 = 0.33ωi
Answer:
4NaBr + 2CaF2 ---------- 4 NaF + 2CaBrz
Explanation:
Full outer shell of electrons, they are colorless and odorless ,their melting and boiling points are close together which gives them very narrow liquid range
Mass of the system is 25.2 kg
Calculation:
F=ma
m = F/a where a = m/t^2
a=2.3/(1.3)^2 = 1.36 m/s^2
m=34.3/1.36
m=25.2 Kg
