To answer this problem, we must remember that momentum is
conserved. Therefore,
Initial momentum = Final momentum
In this case we use angular momentum which it is defined
as:
Momentum =0.5 m ω^2
So finding for final angular velocity, ωf:
mi * ωi^2
= mf * ωf^2
120 kg * (0.5 rev / s)^2 = (120 kg + 22 kg) * ωf^2
ωf^2
= 0.2113
ω<span>f = 0.46 rev/s</span>
-- reduce the length of a wire to 1/2 . . . cut the resistance in half
-- reduce the diameter to 1/4 . . . reduce the cross-section area by (1/4²) . . . increase the resistance by 16x .
-- R2 = (R1) · (1/2) · (16) = 8 · R1
<em>-- R2 / R1 = 8</em>

Answer:
What is it called when the right side of a design is reflected across a central axis and mirrored on the left side of the design?
The correct answer to this question is this one: B. 5.89 feet
<span>The area of a circular trampoline is 108.94 square feet. The radius of the trampoline is 5.89 feet.
</span>
For a circle,
A = (pi)r^2
108.94 ft^2 = (pi)r^2
r^2 = (108.94 ft^2)/(pi)
r = sqrt(108.94/pi) ft
r = 5. 89 ft
