Question 1

In the figure below, a hoop (radius R = 1.0 m, mass = 2.0 kg) having four spokes of negligible mass is suspended from a pivot a distance d = .25 m above its center of mass. The angular frequency (in rad/s) for small oscillations is approximately



◦
4.0

◦
2.5

◦
1.5

◦
1.0

◦
0.5


Question 2

John says that the value of the function cos[ω(t + T) + ϕ], obtained one period T after time t, is greater than cos(ωt + ϕ) by 2π. Larry says that it is greater by the addition of 1.00 to cos(ωt + ϕ). Which one, if either, is correct?

◦
John, because ωT = 2π.

◦
John, because ωT = 1 radian.

◦
Larry, because ωT = 2π.

◦
Larry, because ωT = 1 radian.

◦
Neither, because cos(θ + 2π) = cosθ.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
