Answer:
60,000 kgm/s
Explanation:
momentum equation,
momentum = mass × velocity.
mass = 2000kg
velocity = 30m/s
when multipled you get = 60,000 kgm/s

Answer : 2 (two)
For every O ion, two Na ions are needed to balance charges.
Answer:
T = 5.66 s
Explanation:
The system formed by the bar plus ball forms a physical pendulum
w =
the moment of inertia of a rod held at one end is
I = m L²
we substitute
w =
in this case the turning distance and the length of the rod are equal
d = L
w =
angular velocity and period are related
w = 2π / T
2π / T =
T = 2π
let's calculate
T = 2π
T = 5.66 s
