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

Examine the system of equations.
MakcuM [25]

Answer:

\boxed{\boxed{\sf x=-3}}

Step-by-step explanation:

\sf y = -3x - 2

\sf y=7

We'll substitute y into the equation:

\sf 7 = -3x - 2

Switch sides:

\sf -3x-2=7

Add 2 to both sides

\sf -3x-2+2=7+2

\sf -3x=9

Divide both sides by -3:

\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}

\sf x=-3

Therefore, the value of x/solution is -3

Find a of this angle.
Mice21 [21]

In a triangle, the total angle is 180 degrees. A straight line is always 180 degrees. With this in mind, the following can be obtained:

a + 2x + {57}^{o}   =  {180}^{o}  \\ 5x + a =  {180}^{o}

These are simultaneous equations.

a + 2x +  {57}^{o}  = 5x + a \\ 3x =  {57}^{o}  \\ x =  {19}^{o}  \\ 5x + a =  {180}^{o} \\ 5( {19}^{o}  ) + a =  {180}^{o}  \\ a =  {85}^{o}
