Answer:
K1/K2=4
Step-by-step explanation:
The kinetic energy of a rotating sphere is given by:
The moment of inertia of a solid sphere is given by
The initial kinetic energy is therefore
The final kinetic energy is given by
Therefore the relation K1/K2 if R2 = 0.5R1
The text says nothing about the final angular velocity just the collapse of the collapse of the radius
She made 3 sandwiches because 5-2 3/4 = 2 1/4.
2 1/4 as an improper fraction=(4*2)+1=9/4
9/4 / 3/4=3.
Answer:
C. 55°
Step-by-step explanation:
Note the total measurement of angles for a triangle. The total measurement of all angles in a triangle = 180°
Note that m∠C is a right angle (as shown through the square), and that right angles = 90°
Subtract to find the measurement of the unknown angle (∠B)
∠B = 180 - (∠A + ∠C)
∠B = 180 - (35 + 90)
Simplify. Combine like terms. First, add (solve parenthesis), then subtract.
∠B = 180 - (125)
∠B = 55
m∠B = C. 55°
