Answer: A scalar quantity has magnitude but no particular direction and a vector quantity has magnitude and acts in a particular direction.
Explanation:
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
This doesn’t makes sense at all yes the sheer is ,383
