Apotter's wheel, with rotational inertia 46 kg · m2, is spinning freely at 40 rpm. the potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. if the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay?

mass of clay = 8 kg

Explanation:

Rotational inertia of wheel =

Angular speed of wheel =ω₁ = 40 rpm = 4.188 rad/sec

Clay drops on wheel from distance = r= 1.2 m

Angular speed of clay and wheel = ω₂ = 32 rpm = 3.35 rad/sec

To find:

Mass of clay = M =?

Angular momentum before clay drop =

After collision, angular momentum =  

Using concept of conservation of angular momentum

                                             L₁ = L₂

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
