Asmall blob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius r and moment of inertia i0 that is rotating freely with angular speed ω0 about its vertical fixed-symmetry axis. (use any variable or symbol stated above as necessary.) what is the postcollision angular speed of the turntable-putty system?

Explanation:

Mass = m

Radius of turn table = R

Initial moment off inertia of table = Io

Initial angular velocity is =ωo

As we know that if there is no any external torque on the system then its angular momentum will remain conserve .

So initial angular momentum of table = Io x ωo

Now lets take speed of the mass and turn table system will become ω

Final inertia of system is I

Final linear momentum

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
