A flywheel spins at a constant rate of 2,410 rpm. If the flywheel radius is 6.10 cm, what is the centripetal acceleration of a point on the edge of the flywheel in m/s^2? A flywheel starts at rest and reaches the angular velocity 31.5 rad/s in 5.6 s. What is the angular acceleration of the flywheel in rad/s^2?

A solid cylinder has a mass of 34.0 kg and radius 1.22 m. What is the moment of inertia of the cylinder about its central axis in kg m^2?

A solid sphere has a mass of 12.0 kg and radius 1.14 m. What is the moment of inertia of the sphere about an axis running through its center in kg m^2?

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

god i hope this !

false
