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:
Evolutionary
Explanation:
Because our ancestors were afraid of these poisonous spiders and snakes which lead to them to telling their kids of these dangers. Their kids will fear them without even encountering any and this will also be passed on to their future generations.
If magnification is less than one it means the image is the same exact size as the object.
Answer:
d
Explanation:
this is just common sense, why did you even need to ask?
Work is force times distance
pressure is force over area
hence pressure times volume will give us force times distance aka work
1.1 atm is 111.458 kPa
si units
111.458 kPa times 2.3 L equals 256.35 J
