Answer:
Explanation:
angular acceleration α = 6.61 / 8.97 = .737 rad / s²
moment of inertia = 1/3 m L²
= 1/3 x 1.13 x .899²
= .3045 kg m²
torque applied = moment of inertia x angular acceleration
= .737 x .3045 = .2244
If be the force
Torque
= F x .899 = .2244
F = .25 N ,
The student that measured the mass to be 16110g got closest to the known result. She is off by 10 g.
Answer:
the moon has different gravitational force.
Positive - Friction allows us to create heat in a desperate situation, like being lost in the woods. If we didn't have friction, we would probably freeze to death.
Negative - Friction can also cause unwanted fires, such as forest fires. If friction didn't exist, we wouldn't have these.
