Answer: 5 faces step by step explanation:
<span>1.5 rev/s
Since angular momentum is conserved, the product of the moment of inertia and the rotational rate will remain a constant. So, assuming X as the desired rate of rotation we have:
X * 2.9 = 4.8 * 0.90
Now solve for X
X * 2.9 = 4.8 * 0.90
X * 2.9 = 4.32
X = 1.489655172
So when her arms and one leg go outward, her rotation slows to 1.489 rev/s. Rounding to 2 significant figures, gives 1.5 rev/s.</span>
T( 1.50+ 1.25) + 10.00 < 20.00
2.75t + 10.00 < 20.00
2.75t < 10.00
T < 3.63
Partial bulbs and puts can't be bought, so Anika cannot spent the full $20.00.
Therefore, t < 3 if t can be a whole number.
