A spinning giant star of initial radius R1 and angular speed ω1 suddenly collapses radially inward reaching a new radius R2 = 0.
tiny-mole [99]

Answer:

K1/K2=4

Step-by-step explanation:

The kinetic energy of a rotating sphere is given by:

K=\frac{I*\omega^{2} }{2}

The moment of inertia of a solid sphere is given by

I=\frac{2MR^{2} }{5}

The initial kinetic energy is therefore

K_1=\frac{2MR^{2}*\omega^{2} }{10}

K_1=\frac{MR_1^{2}*\omega^{2} }{5}

The final kinetic energy is given by

K_2=\frac{MR_2^{2}*\omega^{2} }{5}

Therefore the relation K1/K2 if R2 = 0.5R1

\frac{K_1}{K_2} =\frac{5M(R_1)^{2}*\omega^{2} }{5*M(0.5R_1)^{2} \omega^{2}}

The text says nothing about the final angular velocity just the collapse of the collapse of the radius

\frac{K_1}{K_2} =\frac{1 }{(0.5)^{2} }=4

Have the conditions for inference been met?
alekssr [168]

Answer: the answer is A

Step-by-step explanation: because the original question does not state that the swimmer “randomly selected” the members. It only says the swimmer “selects” 10 members. Therefore, it is A (The sample is not random)

youre welcome
