The equivalent of Newton's second law for rotational objects is given by:
where
is the net torque acting on the object
is its moment of inertia
is its angular acceleration
For a hoop rotating around its perpendicular axis, the moment of inertia is
where m is the mass and r the radius. By using the data of the wheel, m=0.750 kg and r=33.0 cm=0.33 m, we find
and since the torque is
, the angular acceleration of the wheel is
Answer:
b
Explanation:
I believe its B and I'm pretty positive it is
The answer is True since thats what usually goes on
How many km go into mm? Also how many cm go into km?
1km = 1000m = 1000 x 1000 mm.
1000,000 mm go into 1 km.
0.000,001 km into 1mm
---
1km = 1000m = 1000 x 100 cm.
100,000 cm go into 1 km.
0.000,01 km into 1cm
