An ice skater has a moment of inertia of 5. 0 kg∙m2 when her arms are outstretched. At this time she is spinning at 3. 0 revolut
Sindrei [870]

Answer:

2440.24 J

Explanation:

Moment of inertia, I1 = 5 kg m^2

frequency, f1 = 3 rps

ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s

Moment of inertia, I2 = 2 kg m^2

Let the new frequency is f2.

ω2 = 2 x π x f2

here no external torque is applied, so the angular momentum remains constant.

I1 x ω1 = I2 x ω2

5 x 6 π = 2 x 2 x π x f2

f2 = 7.5 rps

ω2 = 2 x π x 7.5 = 15 π

Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J

Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J

Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J

C=59(F−32)The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in de
Rama09 [41]

Answer:

D

Explanation:

Our answer choices are:

- A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 5/9 degrees Celsius.

- A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.

- A temperature increase of 59 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.

Let's try the first one. We can just choose any temperature and then use the number 1 larger than it; let's do F = 10:

C = (5/9) * (10 - 32) = (5/9) * (-22) ≈ -12.2

When F = 10 + 1 = 11:

C = (5/9) * (11 - 32) = (5/9) * (-21) ≈ -11.7

We see that indeed, -11.7 - (-12.2) ≈ 0.56 ≈ 5/9, so the first is correct.

For the second, let's see what happens when C = 10 and when C = 11:

10 = (5/9) * (F - 32)

F = 50

11 = (5/9) * (F - 32)

F = 51.8

Again we see that indeed 51.8 - 50 = 1.8

So, the second choice is also correct.

Thus, the answer is D.
