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

What is the equation of the given line in standard form? Use integer coefficients (no decimals or fractions!). y = 3 over 5x - 3
Mazyrski [523]

Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis So we have one point Now since the slope is comprised of the "rise" over the "run" this means Also, because the slope is , this means: which shows us that the rise is 3 and the run is 5.
